Part 1
Plug in x = 8 and simplify
h(x) = -2x-10
h(8) = -2(8)-10
h(8) = -16-10
<h3>h(8) = -26</h3>
================================
Part 2
Replace h(x) with 14. Follow PEMDAS in reverse to solve for x.
h(x) = -2x-10
14 = -2x-10
14+10 = -2x
24 = -2x
24/(-2) = x
-12 = x
<h3>x = -12</h3>
If x = -12, then h(x) = 14
In other words, h(-12) = 14
------
Check:
h(x) = -2x-10
h(-12) = -2(-12)-20
h(-12) = 24-20
h(-12) = 14
Answer:
x=10 and scale factor is 15/9 or 1 2/3
Step-by-step explanation:
FIrst, find scale factor. 9 to 15. Times by 15/9 or 1 2/3.
Find x. 6*1 2/3 = 10
Answer:
5
Step-by-step explanation:
12+12+12= 36
36-7= 29
3+3+3=9
29-9=20
