2 answers:

7 0

Sum of 54: X + Y = 54
Difference is 4: X - Y = 4

Solve for one variable first.

X = 4 + y (rewritten from second equation)

Now plug into the first equation for x

4 + y + y = 54
4 + 2y = 54 (subtract 4)
2y = 50 (divide by 2)
Y = 25

Now use Y to solve for X

X - 25 = 4 (add 25 on each side)
X = 29

Rewrite the function f(x)=-4(x-3)^2+16 in the form f(x)=ax^2+bx+c

elena55 [62]

Answer:

f(x) = - 4x² + 24x - 20

Step-by-step explanation:

Given

f(x) = - 4(x - 3)² + 16 ← expand the factor using FOIL

= - 4(x² - 6x + 9) + 16 ← distribute parenthesis by - 4

= - 4x² + 24x - 36 + 16 ← collect like terms

= - 4x² + 24x - 20
