Answer:

-3

Step-by-step explanation:

To solve you replace the -z with 2 because the -2=z not -z. With the z in parenthesis being negative it basically means invers so you would put the invers or opposite of -2 in the parentheses.

-1-(2)

-1+-2

=-3

What is the complete square of y=x^2-16x+17

aliina [53]

Y = x^2 - 16x + 17
-16/2 = (-8)
(-8)^2 = 64
Add 64 and subtract 64
y = x^2 - 16x + 64 + 17 - 64
y = (x - 8)^2 - 47

Guys, please help me out. Thanks.

Answer:

w = 13

Step-by-step explanation:

Using the method of cross- multiplying

• $\frac{a}{b}$ = $\frac{c}{d}$ ⇒ ad = bc, thus

42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides

42w + 462 = 28w + 644 ( subtract 28w from both sides )

14w + 462 = 644 ( subtract 462 from both sides )

14w = 182 ( divide both sides by 14 )

w = 13
