Answer:
35$
Step-by-step explanation:
1/4 of 60 is = 15 and 1/4 of 80 is = 20
Add 20 and 15 = 35$
When it tells you to find h(2), that means you plug in 2 for x.
If 2x^3 (to the third power)
2(2)^3-3
1. PEMDAS, exponents first
2^3=8
2. multiply
8x2=16
3. subtract
16-3=13
Hope this helps!
I think if I do this correctly, the answer is x<-1
The ratio 21:28 in it's simplest form is 3:4
Domain:

As we see in a numerator we have a square, so

is always 0 or more. Now, there are two possibilities:
1.

We divide two numbers, and first one is positive, so the result will be also positive (it canot be 0 in this case) when

. So:

2.

In this case the result wil be 0 (we have ≥ 0 in our inequality, so it will be a solution).

So the solution to this inequality is:
