Answer:
Domain { 0 ≤ r≤ 18}
Range = {0≤ c ≤ 31.5}
Step-by-step explanation:
The domain is the values that r can take
He can goes on each ride up to 1 time
R can be from 0 rides to 18 rides since there are only 18 rides
Domain { 0 ≤ r≤ 18}
The range is the output
If r = 0 then he spends no money
if r =18 then 1.75*18 =31.5
Range = {0≤ C(r) ≤ 31.5}
Answer:
-1.4 and 3.4
Step-by-step explanation:
The solutions of a quadratic are the x values of the x-intercepts where the function crosses the x-axis.
Type in your equation to graph. Then zoom in on the x-axis and find where the function crosses.

Answer:
420
Step-by-step explanation:
Assuming this is the problem:
At a school, 147 students play at least one sport. This is 35% of the students at the school. How many students are at the school?
147/35 = x/100
35x=147*100
35x=14,700
x=420
Answer:
x = √149 km
Step-by-step explanation:
Pythagorean theorem
x^2 = 10^2 + 7^2
x^2 = 100 + 49
x^2 = 149
x = √149
