Answer:
6k-5
Step-by-step explanation:
8k-(5+2k) write the equation out

Answer:
44
Step-by-step explanation:
The equation is of the form a
x
²+bx +c = 0 where
a = 5, b= -2, c= -2
The Discriminant is given by:
Δ=
b²−
4 * a * c
= (−2²)− (
4 * 5 * (
− 2
)
)
= 4
+ 40
= 44
Answer:
-15
Step-by-step explanation:
start from the inside and go out.
So first plug in -3 into g(x)
g(-3) = -3 - 7 = -10
then plug in -10 into f(x)
f(-10) = 2(-10) + 5 = -15
so f(g(x)) = -15
