Answer:

Step-by-step explanation:

As given, we have here, an original equation: f(x) = 3x + 2.

To work out f(a - 4), we substitute x = a - 4 into original equation.

f(a - 4) = 3(a - 4) + 2

We apply the distributive property to keep going.

f(a - 4) = 3a - 3*4 + 2

We perform the multiplication of 3 and 4.

f(a - 4) = 3a - 12 + 2

We perform the addition of (-12) and 2 to finalize the answer.

f(a - 4) = 3a - 10

This is the final answer

I hope this helps!

12345 [234]

Answer:

Point (2, 20) does not lie on the given curve.

Step-by-step explanation:

Let us see explanation:

$f(x) = 2. \: {5}^{x} \\ \\ \therefore \: f(x) \: at \: x = 2 \\ f(2) = 2. {5}^{2} = 2.25 = 50 \\ \\ hence \: at \: x = 2 \: \: f(x) = 50 \\ \therefore \:point (2 \: \: 20) \: does \: not \: lie \: on \: the \: \\ \: \: \: \: \: curve.$

Select the three equations that pass through the points (-4, -16) and (5,2).

dezoksy [38]

Answer:

The equation of the line is $y-2 = 2(x - 5)$ , that passes through points $(-4, -16)\ and\ (5,2)$

Step-by-step explanation:

Given points are $(-4, -16)\ and\ (5,2)$

We need to write the equation of the line that passes through these points

First, we will find slope of this line

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-(-16)}{5-(-4)}\\\\m=\frac{2+16}{5+4}\\\\m=\frac{18}{9}=2$

So, our slope is $2$ . Now, we will plug the point $(5,2)$ in the equation below.

$(y-y_1)=m(x-x_1)\\y-2=2(x-5)\\$

So, the equation of the line is $y-2 = 2(x - 5)$ .

The O! Natural Company is trying to get schools in the state to sell their juice product.

Phoenix [80]

For a. divide 125 by 300 then multiply by 100

The answer for a. is 41.66%

For b. convert percentage to decimal divide by 100 then multiply 0.15 by 2.25 to get 0.3375‬. Round it off to 0.34 and subtract that from 2.25 to get

The answer for b. is $1.91

For c. you have to figure out the difference first. 2.50 minus 2.00 is 0.50

So then what percent of 2.00 is 0.50

Divide 2.00 by 0.50 to get 4.

The answer for c. is 4%

Honestly this was kinda rushed because I'm in the middle of a quiz so yea hope this helps you.
