F(x) = X^2 - 11x - 60
Two terms that multiply to -60 and add to -11 so...
F(x) = (X - 15) (x + 4)
Your x-intercepts would be 15 and -4.
Answer:
x = 3
Step-by-step explanation:
Set up as proportion and cross multiply to solve:
3/4 = 2.25/x
x = 3
Answer:
46
Step-by-step explanation:
11 = -3k - 22 - 8k....combine like terms on the right side
11 = -11k - 22 ...add 22 to both sides
11 + 22 = -11k
33 = -11k....divide both sides by -11
-33/11 = k
-3 = k <===
