- h(x) = f(x) + g(x) =

- h(x) = g(x) – f(x) =

- h(x) = 4g(x) =

<u>Step-by-step explanation:</u>
Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or
.
10. Find h(x) = f(x) + g(x).
⇒ 
⇒ 
⇒ 
⇒ 
11. Find h(x) = g(x) – f(x).
⇒ 
⇒ 
⇒ 
⇒ 
12. Find h(x) = 4g(x).
⇒ 
⇒ 
⇒ 
Because 1 minute is 60 seconds, and it takes 12 seconds to download 8 apps, the first thing we need to do is find out how many "sets" of 12 seconds can go in 60 seconds:
60 / 12 = 5
Now, all we have to do is multiply the number of apps by 5, and we get our answer:
8 · 5 = 40
So, it would take Deandre 1 minute to download 40 apps.
Answer:
11 squared - X squared. That would be your answer.
Step-by-step explanation:
I just happened to notice that 32 is incorrect, it should be A
33. (21x+14)/5y+4y*5y/7(3x+2)
((21x+14)*5y)/((9y*7(3x+2)
((5(21x+14)/63(3x+2)
35(3x+2)/63(3x+2)
5/9 is the answer
37. |-3--7|+|-7--3|
|-3+7|+|-7+3|
|4|+|-4|
4+4=8
8 is the correct answer
38. 99999/1 you can 99999
Answer:
x=2
Step-by-step explanation:
If 3x + y = 7, then y= 7 - 3x.
Substitute in x - 2y = 0
So:
x - 2(7-3x)=0
x-14+6x=0
7x=14
x=2
