12. Correct, B
13. Correct, E
14. A
15. B
You can eliminate fractions by multiplying the whole thing by 7.
... -x +28 ≥ 21x
Now, add x to get all x-terms on the right. Then, divide by the coefficient of x.
... 28 ≥ 22x
... 28/22 ≥ x
This fraction can be reduced, so we have ...
... A. x ≤ 14/11
The answer is D because you have to sneer what is in the parentheses first
You just have to find the formula of each figure you can search it in internet or whatever then you have to solve those numbers in the formula
Answer:
B
Step-by-step explanation:
To evaluate (f ○ g)(- 4), first evaluate g(- 4) then substitute this value into f(x)
g(- 4) = 3(- 4) - 5 = - 12 - 5 = - 17, then
f(- 17) = 4(- 17) + 7 = - 68 + 7 = - 61 → B
