Question 13 I don’t know how to do it
Gekata [30.6K]

Answer:

y = - \frac{1}{4} (x - 1)²(x + 2)(x + 6)

Step-by-step explanation:

The roots from the graph are

x = - 6 , then factor is (x + 6)

x = - 2 , then factor is (x + 2)

x = 1 ( multiplicity 2 ) , then factor is (x - 1)² then

y = a(x - 1)²(x + 2)(x + 6) ← a is a multiplier

To find a substitute any point on the graph into the equation

Using (0, - 3 ), then

- 3 = a(- 1)²(2)(6) = 12a ( divide both sides by 12 )

- \frac{1}{4} = a

Then

y = - \frac{1}{4} (x - 1)²(x + 2)(x + 6)

If 8y - 8=24 find the value of 2y ​
Mariulka [41]

Answer:

2y =8

Step-by-step explanation:

8y - 8 = 24

First let's find the value of y

Collect like terms and simplify ;

8y = 24 + 8 \\ 8y = 32

Divide both sides of the equation by 8

\frac{8y}{8}  =  \frac{32}{8}

Simplify

y = 4

Substitute 4 for y into 2y

2y \\  = 2(4) \\  = 4 \times 2 = 8
