Answer:

Maya spends $22,500 in those 5 year and Darrel spent $22,000 in all. So, Maya spent more than Darrel by $500. If Darrel were to sell his car, he would have gained $8,500 and then have $13,500 gained from after the car payment, but after getting a new one, he would have spent $35,000. So, I think Maya would be better off. (I don't really know the meaning, sorry if it's wrong.)

Answer:

\( \frac{3x}{3 - 2x} \)

Step-by-step explanation:

Here,

f(x) = y

\(y = \frac{3x}{2x + 3} \)

or , swapping x with y

\(x = \frac{3y}{2y + 3} \)

now to solve for y we get

\(y = \frac{3x}{3 - 2x} \)

now we put f inverse x instead of y

\( {f}^{ - 1} (x) = \frac{3x}{3 - 2x} \)

I am done.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Challenge 1

We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.

If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.

Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).

Remember that b cannot be negative.

===========================================

Challenge 2

In the general template provided, enter x = 0.

y = a(b)^x

y = a(b)^0

y = a(1) (1)

y = a

When x = 0 is plugged in, the result is y = a.

The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.

Answer:

The conclusion that can be determined from the dot plot is that:

The number of observations is 15, as there are 5+6+3+1=15 dots in total.

The median of the data set is 10, as it is the middle value when the data is arranged in order.

The mean of the data set cannot be determined from the dot plot.

The range of the data set is 12, as it is the difference between the highest value (12) and the lowest value (9) in the data set.

Answer:

0.2x + 5 > 2

Step-by-step explanation:

The arrow is pointing to the right so immediately you know that the sign will be greater than (>). So we can eliminate the choices, 0.3x + 8 < 3 and 0.4x +7 < 1.

Now looking at the two options that are left, we can simply solve them.

         0.2x + 5 > 2

Subtract 5 on both sides

         0.2x > -3

Then divide 0.2 on both sides and you're left with:

         x > -15

We don't need to solve the other inequality because we know that the arrow is pointing to the right, suggesting that x is greater than -15.

What makes a NUMBER rational is the ability to have a perfect square root, cube root, or have these components: Perfect square/cube, whole number, repeating (pattern) decimal, termination decimal, and I think one more that I can't remember.

The properties of the rational exponents are given and a rational equation is of the form b = aˣ

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the rational exponent equation be A

Now , the properties of the exponent equations are

mᵃ×mᵇ = mᵃ⁺ᵇ

The powers of the exponents are added together

mᵃ / mᵇ = mᵃ⁻ᵇ

The powers of the exponents are subtracted together

( mᵃ )ᵇ = mᵃᵇ

The powers of the exponents are multiplied together

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

Any number raised to the power of 0 is 1

m⁻ᵃ = ( 1 / mᵃ )

Hence , the exponents are solved

Answer:The lengths of AB and EF are 10 and 2 respectively

If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;

AB/DE = BC/EF

5x/4 = 5/x

5x² = 20

x² = 20/5

x² = 4

x = 2

Since the value of x is 2, length of AB is 5x = 5(2) = 10

Since EF = x, hence EF = 2

The lengths of AB and EF are 10 and 2 respectively

\(\frac{1}{w^{6} }\) i hope this helps!!

Answer:

The simplified expression is 1/w^6.

Step-by-step explanation:

Using the product of powers exponent rule, we have

w^3 * w^(-9) = w^(3 + (-9)) = w^(-6).

However, the problem says to write the expression using only positive exponents. Here's an example of how to interpret negative exponents as positive exponents:

3^2 = 9

3^1 = 3

3^0 = 1

3^(-1) = 1/3

(and keeps on dividing by three onward)

Here, we see that 3^(-1) = 1/3^1.

Applying the same logic here, we have

w^(-6) = 1/w^6.

Answer:

Answer:

26.67m/s²

Step-by-step explanation:

From the question we are given

Final velocity = 30m/s = v

Initial velocity = 10m/s = u

We were not given time but we were given distance = 15m

Therefore we would be using the formula:

Acceleration = v² - u²/ 2s

Where S = distance

v = final velocity

u = initial velocity

Acceleration (a) = 30² - 10²/ 2 × 15

a = 900 - 100/ 30

a = 200/30

a = 26.666666667m/s²

a = 26.67m/s²

Less than 4

add 5 to both sides and u get the equation 14x<-1 then divide both sides by 14 to get x alone. that leaves you with x< -1/14 wich is then less than 4
