(30 points worth, pls help) Use the function f(x) to answer the questions. f(x) = −16x2 + 60x + 16 Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)

Step-by-step explanation:

x intercept y=0

0 = 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)

x intercept y=0

0

= 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)

Step-by-step explanation:

0  = 16x^2 - 60x -16

0 = 16x^2 + 4x - 64x - 16

0 = 4x (4x + 1) - 16 (4x + 1)

0 = (4x - 16) (4x + 1)

4x - 16 = 0 or 4x +1 = 0

4x = 16 or 4x = -1

x = 4 or x = -1/4

(4,0) and ( -1/4,0)

there will be 35 boys in each team. : )

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
