Hello,
Do you mean
h(x)=2x+5
g(x)=8-3x
h(g(x))=h(8-3x)=2(8-3x)+5=16-6x+5=21-6x
h(g(1.5))=h(g(3/2))=21-6*3/2=21-9=12
Square roots are rational and it equals 5 and 5 is rational
Answer:
See below.
Step-by-step explanation:
So we know that a gym membership costs $25 plus $14 each month.
In other words, the one-time cost is $25 and there will be a cost of $14 each month.
We can write this as:

Where f(x) equals the total cost given the number of months x.
For 6 months, the total cost will be:

Melanie:
Amount after 5 years = 4000(1 + 0.04)⁵ = $4867
Gina:
Amount after 5 years = 4000 + 5(0.045 x 4000) = $4900
Answer: Gina has the greater balance and her balance is $4900.
Answer:
7 millimeters
Step-by-step explanation:
Volume is the area of the base times it's length.
140/10 is 14
so the area of the triangle is 14
the formula for area of a triangle is base times height divided by 2
so
d x 4/ 2 = 14
multiply both sides by 2
d x 4 = 28
divide both sides by 4
d=7
