Answer:
The answer is 639.
Step-by-step explanation:
42.6 × 15
639
F(x) = 2x + 1 and g(x) = -5x + 2
f(g(x)) = 2(-5x + 2) + 1 = -10x + 4 + 1 = -10x + 5
f(g(3)) = -10(3) + 5 = -30 + 5 = -25
Answer:
a.x=4
b.x=4
c.(b)
Step-by-step explanation:
We are given that

a. First we adding x on both sides we get


Now, subtract 5 on both sides we get


b.
We are subtracting 9 from both sides we get



We can solve equation both approach a and b
But I prefer (b) because in approach (b)
There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .
Hence, I prefer approach (b)
Answer:
a=-79/2=-391/2=-39.5
Step-by-step explanation:
a+45=11/2 subtract 45 from both sides
a=11/2-45 convert 45 to fraction 90/2
a=11-90/2 subtract 90 from 11 to get -79
I think you have to divide 984 and 41 which gets you 24
