1 answer:
Answer:
The domain is [1,∞)
Step-by-step explanation:
The given functions are:

and

We want to find the domain of

Simplify to get:

Answer:
1:×4
m×4=(8+2n)×4
4m=32+8n
now,
1:×4 - 2:
4m-4m = 32+8n -4+4n
0=(32-4) +(8n-4n)
0=28+4n
28=-4n
n= -7
n=-7. 1:,
m=8+2n
m=8+2×(-7)
m=8-14
m=-6
9 x ≥ 117
Divide both sides by 9 :
9 x / 9 ≥ 117 / 9
x = 117 / 9
x ≥ 13

Answer:
Maggie is 5 years old
Step-by-step explanation:
3M-4+M=16
