Answer:
C is the answer i did this before!
Step-by-step explanation:
Answer:
f(x) = 2x^2 - 6x - 20.
Step-by-step explanation:
(-2, 0) and (5, 0) are 2 zeroes of the function so we can write the function as
f(x) = a(x + 2)(x - 5) where a is a constant.
Now as (4, -12) is a point on the graph:
-12 = a(4 + 2)(4 - 5)
-12 = a * 6 * -1
-6a = -12
a = 2.
So f(x) = 2(x + 2)(x - 5)
f(x) = 2x^2 - 6x - 20.
Answer:
1) m<BFD is a triangle
2) AC is a line segment
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
Assuming you mean 60 + 6b = 48
subtract 60 from both sides: 6b = 48 - 60 = -12
Now divide both sides by 6 to solve for b: b = -12/6 = -2
