One system of quadratic equations that has solutions of (-3, -3) and (3, -3) is:

x^2 + y^2 = 18

x + y = 0

You can check that for x = -3 and y = -3, the left-hand side of both equations is equal to the right-hand side, and the same is true for x = 3 and y = -3.

Answer: The answer is 1

Step-by-step explanation: The distance between -7 and -3 is 4 then half the distance in between -7 and -3 is going to be -5 because we just clarified that the distance between -7 and -3 is 4 so we did 4/2 and got 2 so we can figure out whats the distance between each point. Now that we figured that out we can determine what value the blue dot is if the value between each point is 2 then we can make out what the rest of the points on the line. If we from -3 to the blue point that would be 1.

Answer:

-11

Step-by-step explanation:

Notice how

\(f(x)=x^{2} +8x+1\)

So when we have

\(f(-6)=(-6)^{2} +8(-6)+1= 36-48+1=-11\)

The answer is:

f(-6) = -11

Step-by-step explanation:

Plug in -6 for x:

\(\sf{f(x)=x^2+8x+1}\)

\(\sf{f(-6)=(-6)^2+8(-6)+1}\)

Simplify this:

\(\sf{f(-6)=36-48+1}\)

\(\sf{f(-6)=-12+1}\)

\(\sf{f(-6)=-11}\)

Step-by-step explanation:

1) 12, 14

This is the answer because each increasing number was increased by 2, so if you add 2 to 10, you'd get 12. If you add 2 to 12, you would get 14.

2) 50, 54

Same explanation as above but for the number 4.

3) 68, 50

Same explanation as 1, but with subtracting the number 6.

4) 67, 69

Same as number 1

5) 103, 101

Answer:

Volume≈29.32

Step-by-step explanation:

To find the volume of the prism we just multiply all the measures

The volume is 24 cm³

If the sugar cubes have 1 cm³ of volume, to find how much sugar cubes fit in the box we must divide the volume of the box by the volume of the sugar cubes

Therefore we can fit 24 sugar cubes

Using a system of equations, the potter made 5 bowls and 10 planter pots.

A system of equations, which is also known as simultaneous equations, is two or more equations solved simultaneously.

There are four methods for solving simultaneous equations: graphical, elimination, substitution, and matrix methods.

Bowl            Planter Pot

8 hours       18 hours

2 pounds    14 pound

Total hours worked in summer = 220 hours

Total pounds of clay available = 150 pounds

Let b = bowl and p = planter pot

Equation 1: 8b + 18p = 220

Equation 2: 2b + 14p = 150

Equation 3 from Equation 2: b = 75 - 7p

Substitute b in Equation 1 with the value of b in Equation 3:

8(75 -7p) + 18p = 220

600 - 56p + 18p = 220

-38p = -380

p = 10

In Equation 3:

b = 75 - 7(10)

b = 5

Thus, by setting and solving simultaneous equations, we can conclude that the potter made 5 bowls and 10 planter pots during the summer with 150 pounds of clay, working for 220 hours.

The vertices of the feasible region are (0 , 15/2) , (21/11 , 19/11) and (6 , 0)

Given, the constraints of a problem

2x+3y≥12

x ≥ 0

y ≥ 0​

On solving the equations, we get

( 2x + 3y ≥ 12 ) × 2

( 5x + 2y ≥ 15 ) × 3

4x + 6y ≥ 24

15x + 6y ≥ 45

On subtracting, we get

Bernie drove 1.125 times as fast as Janelle.

To determine who drove faster, we can calculate the average speed (in km/h) of each driver using the formula:

average speed = distance / time

For Janelle:

average speed = 60 km / (5/6 hours) = (60 km) x (6/5 hours) = 72 km/h

For Bernie:

average speed = 54 km / (2/3 hours) = (54 km) x (3/2 hours) = 81 km/h

Therefore, Bernie drove faster than Janelle. To determine how many times as fast, we can divide Bernie's average speed by Janelle's average speed:

81 km/h / 72 km/h = 1.125

Subtracting decimals, just like adding decimals, is similar to subtracting whole numbers. Just like adding decimals, the only difference is that we line up according to the decimal point instead of the last digit

One type of number that has a whole number and a fractional component separated by a decimal point is a decimal. The decimal point is the dot that appears between the parts of a whole number and a fraction. An example of a decimal number is 34.5.

Comparable to subtracting whole numbers is the operation of adding and subtracting decimals. The only difference between adding decimals and doing so is that we line up according to the decimal point rather than the last digit.

Answer:

Step-by-step explanation:

The vector function that represents the curve of intersection is: r(t) = [x(t), y(t), z(t)] =\([t, 4t^2, 5t^2 + 32t^4]\)

To find a vector function that represents the curve of intersection between the paraboloid and the cylinder, we need to express the coordinates (x, y, z) in terms of a parameter t.

Let's start by expressing the cylinder equation in terms of x and y:

y =  \(4x^2\):

We can rewrite this as:

y - 4x^2 = 0

Now, we'll substitute this expression for y in the equation of the paraboloid:

z =\(5x^2 + 2y^2\)

Replacing y with \(4x^2\):

\(z = 5x^2 + 2(4x^2)^2\\z = 5x^2 + 32x^4\)

Now we have the equations for x and z in terms of t:

x = t

z = 5t^2 + 32t^4

To obtain the y-coordinate, we substitute the x value into the equation of the cylinder:

y =  \(4x^2\):

y =\(4t^2\)

Therefore, the vector function that represents the curve of intersection is: r(t) = [x(t), y(t), z(t)] =\([t, 4t^2, 5t^2 + 32t^4]\)

Here says the reason for  ∠1 = ∠4 and ∠2 = ∠3 is same.

We have to find the reason;

So,

From the figure,

∠1 = ∠4 ; Alternate Interior Angles are ≅

∠2 = ∠3 ; Alternate Interior Angles are ≅

Alternate Interior Angles

When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.
