Answer:

y= -13-3x÷7

Step-by-step explanation:

1st Subtract 3x from both sides: 3x-7y-3x=13-3x

2nd Simplify: -7y=13-3x

3rd Divide both sides by -7: -7y÷-7=13÷-7-3x÷-7

4th Simplify: -13-3x÷7

MARK YOU BRAILIST PLEASE ANSWER CORRECTLY AND SHOW YOUR WORK Which process was used to obtain the equation shown in Step 2?

KonstantinChe [14]

Answer:

Step-by-step explanation:

Multiply by 12 on both sides.

Start with step one

y/3 - 1/4 = 5 Multiply both sides by 12

12(y/3 - 1/4) = 5*12

12*y/3 - 12 * 1/4 = 60

3 goes into 12 four times

4 goes into 12 three times. In both cases you are cancelling.

4y - 3 = 60

In the xy-plane, the graph of function f(x) has zeros at −5, −2, and 2. Write the polynomial function.

Alona [7]

Answer:

$f(x) = x^3 +5x^2-4x-20$

Step-by-step explanation:

Given

$Zeros: -5,-2,2$

Required

The polynomial function

If a function has a, b and c as its zeros, the function is:

$f(x) = (x - a)(x - b)(x - c)$

So, we have:

$Zeros: -5,-2,2$

$f(x) = (x - (-5))(x - (-2))(x - 2)$

Open the inner brackets

$f(x) = (x +5)(x +2)(x - 2)$

Expand the difference of two squares

$f(x) = (x +5)(x^2 - 4)$

Expand

$f(x) = x^3 +5x^2-4x-20$
