Ok so your original equation was y=4(x-2)²-1
Therefore we need to expand the bracket to find the original equation.
To do this we need to find (x-2)²=x²-4x+4
Now we multiply this by 4 and subtract 1
4x²-16x+15 Therefore B is the answer

Y = 4(x - 2)² - 1
y = 4(x² - 4x + 4) - 1 
y = 4x² - 16x + 16 - 1
y = 4x² - 16x + 15

<u>y = B(y)</u>

Find x<br><br> 5x-7+8x-55<br><br> 13 POINTS <br><br> Show work please
Law Incorporation [45]

Combine like terms. The 5x is grouped to the 8x and the -7 isgrouped with the -55.

This means 5x + 8x = 13x and -7 - 55 = -62

The new expression is 13x - 62. We can't find the exact value of x because the expression wasn't set equal to anything.

I need help! I forgot how to do this!! Please help!
Dovator [93]

First change the mixed fraction into an improper fraction

7 1/2 = 15/2

Next, change multiply 2 to both numerator and denominator

15 x 2 = 30

2 x 2 = 4

30/4

Each piece needs 3/4 of an inch. Divide 30 with 3

30/3 = 10

c) 10 pieces is your answer

hope this helps
