Write an equation to match this graph.
Answer:
y = x + 7
Step-by-step explanation:
This is a linear equation graph because the line is straight and it is going at a constant rate. You can just either add or subtract the dependent event or the y variable. So I use the linear equation y = mx + b.
Use the y2 - y1 / x2 - x1 to find the slope. The slope is basically m. You can use any coordinate for this.
I will use (2, 9) and (3,10) as the coordinates for an example.
So y2 = 10
y1 = 9
x2 = 3
x1 = 2
10 - 9 / 3 - 2 = 1/1 = 1
1 is the same thing as x.
So the slope is x.
Now in order to find b(or the whole number on the far right), you use one of the x and y coordinates.
For an example I will use (5, 12)
Now all I do is use the formula y = mx + b
y = 12
x = 5
m = 1. M is the same thing as slope.
b is what I must find out.
So I write 12 = 1(5) + b
12 = 5 + b
Then you subtract 5 from 12
and you will get 7.
12 - 5 = 7
The b or the y intercept equals 7.
So the equation for this graph is y = x + 7

The equation for the line is y=x+7
What is the solution to a linear equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
Given here, the points on the line are (2,9) , (3,10) , (4,11) , (5,12) , (6,13)
Let's assume the the equation of the line is y=x+7 then putting on the points on the equation we get
(2,9) 9=2+7
(3,10) 10=3+7
Similarly the equation holds good for all the points in the graph.
Hence, The equation for the line is y=x+7

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)

Answer: 15
Step-by-step explanation:
Write 12% as a fraction: 12/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have: 12/100 of 125.
12/100 × 125
If you are using a calculator, enter 12÷100×125 which will give you 15 as the answer.
A composite figure is shown.
A five-sided figure with two parallel sides. The shorter one is 16 feet. The height of the figure is 22 feet. The portion from the vertex to the perpendicular height is 6 feet. The portion from a point to a vertical line created by two vertices is 6 feet.
Which of the following represents the total area of the figure?
968 ft2
616 ft2
484 ft2
352 ft2
Option (C) 484 ft²
Step-by-step explanation:The Five Sided figure can be divided into 2 Triangles and 1 Rectangle.
The Dimensions of the Triangle that is on the Left are as follows:Length of the triangle = 22 Feet
Breadth of the triangle = 8 Feet
Area of the triangle = (Length * Breadth) / 2
= (22 * 8) / 2
= 176/2
= 88 ft²
The Dimensions of the Triangle that is on the Right are as follows:Length of the triangle = 22 Feet
Breadth of the triangle = 4 Feet
Area of the triangle = (Length * Breadth) / 2
= (22 * 4) / 2
= 88/2
= 44 ft²
The Dimensions of the Rectangle are as follows:Length of the rectangle = 22 Feet
Breadth of the rectangle = 16 Feet
Area of the triangle = (Length * Breadth)
= (22 * 16)
= 352 ft²
The Total Area of the Five Sided figure can be found by summing up the areas of the Triangles and the Rectangle.
The Total Area of the figure is 88 + 44 + 352 = 484 ft²
So, the total area of the figure is 484 ft².

Answer: 36 inches (in.)
Step-by-step explanation:
The first thing you need to do is form a right triangle from the starting point to the hole to the corner where the ball is at. Right triangles have a hypotenuse (the longest side), and two legs (the shorter sides).
We are told next to the drawing that it’s 39 feet from the staring point to the hole (given a straight line). This is the length of our hypotenuse. We are also given the length of one of the legs, with it being 36 feet.
We need to find the length of the last leg, the length from the ball to the hole. To do this, we can use the Pythagorean Theorem. The Pythagorean Theorem states that the square of each of the legs equals the square of the hypotenuse. The formula for the Pythagorean Theorem is \(a^{2} +b^{2} =c^{2}\), with \(a\) and \(b\) being the legs, and \(c\) representing the hypotenuse.
Input the given values into the formula and you get the following:
\(a^{2} +b^{2} =c^{2}\)
\(36^{2} + x^{2} =39^{2}\)
\(\sqrt{36^{2} } +\sqrt{x^2} =\sqrt{39^2}\)
\(36 +x =39\)
\(x=3\)
Therefore, the length from the ball to the hole is 3 feet (ft.).
BUT WAIT
The question asks us to provide our answer in inches (in.), and 1 foot equals 12 inches.
Therefore, the distance from the ball to the hole is 36 inches (in.).
Norma has a credit card that uses the adjusted balance method. For the first
10 days of one of her 30-day billing cycles, her balance was $1850. She then
made a purchase for $160, so her balance jumped to $2010, and it remained
that amount for the next 10 days. Norma then made a payment of $930, so
her balance for the last 10 days of the billing cycle was $1080. If her credit
card's APR is 29%, which of these expressions could be used to calculate the
amount Norma was charged in interest for the billing cycle?
The solution is : The amount Pearl was charged in interest for billing cycle = $19.8
What is interest?Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
here, we have,
Starting balance of Pearl for first 10 days of her 30 days billing cycle =$1120
Purchase made = $ 340
Total Balance after purchase made = $1120 + $340
= $1460
Payment made after 10 days = $580
Balance for last 10 days = $1460 - $580
= $880
Credit Card APR = 27% Annually
Credit Card APR = 2.25% monthly.
Amount charged as an interest for billing cycle = 880 × 2.25%
= 880 × 0.0225
= $19.8
Hence, The amount Pearl was charged in interest for billing cycle = $19.8

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

To solve:
First we have to move 3 units right. This means that we have to increase the x axis, because we move left and right on the x axis. This gets you to the coordinates (4, -3).
Now, to move six units up, add 6 to -3. Instead of counting, using the mathematical way makes it easier to calculate. This gets us a y axis point of 3, since the y axis runs from up to down. When we read the final point out loud, this gives us the answer of ...

Given the points A(3, 1), B(6, y) and C(12, -2) find the value(s) of y if…
(a) The distance AB is 5
(b) The lines AB and BC are perpendicular
[Level - GCSE]
Worth 20 points
I’ll give brainliest if I figure out to use it.
The value of y the distance AB is 5 is -3.
We are given that;
The three points A(3, 1), B(6, y) and C(12, -2)
Now,
We can use the distance formula to find the value of y when the distance AB is 5:
AB = sqrt((6-3)^2 + (y-1)^2) = 5
Simplifying this equation gives:
(y-1)^2 = 16
Taking the square root of both sides gives:
y-1 = ±4
Therefore, the possible values of y are:
y = 1 + 4 = 5 or y = 1 - 4 = -3
To find the value(s) of y when lines AB and BC are perpendicular, we can use the slope formula to find the slopes of AB and BC:
slope AB = (y-1)/(6-3) = (y-1)/3 slope BC = (-2-y)/(12-6) = (-2-y)/6
Since AB and BC are perpendicular, their slopes are negative reciprocals of each other. Therefore:
(slope AB) * (slope BC) = -1
Substituting the slopes into this equation gives:
(y-1)/3 * (-2-y)/6 = -1
(y-1)(y+4) = -18
y^2 + 3y - 4 = -18
y^2 + 3y + 14 = 0
Therefore, by distance the answer will be -3.
