Answer:
what is this
Step-by-step explanation:
Step-by-step explanation:
g(x)=3x+5
g(-3)=3(-3)+5
=-9+5
=-4
We have similar triangles so
12/x = (12+78)/(x+13)
We can skip some algebra by doing the ratio on the pieces. We'll show it works at the end.
12/x = 78/13
x = 12(13)/78 = 2
We check
12/2 = 6
(12+78)/(2+13) = 90/15 = 6, good
Answer: x=2
Answer:
C
Step-by-step explanation:
The numerator being bigger would make it an improper fraction, making it larger than one.
H(f(x))=3(x^2+2)
h(f(x))=3x^2+6
g(h(f(x)))=(3x^2+6)^3+2
g(h(f(-1)))=(3(-1)^2+6)^2+2
g(h(f(-1)))=(3+6)^2+2
g(h(f(-1)))=81+2
g(h(f(-1)))=83
