F(x) = - 55x + 330
The domain is the set of possible input-values, i.e. x-values.
You know that f(x) cannot bebigger than 330 not lower than zero, then construct the inequality:
0 ≤ f(x) ≤ 330
0 ≤ - 55x + 330 ≤ 330
Multilply by - 1 and change the inequality signs:
0 ≥ 55x - 330 ≥ -330
Add 330 to all the members
330 ≥ 55x ≥ 0
Divide by 55
6 ≥ x ≥ 0 => 0 ≤ x ≤ 6
The the possible x-values (practical domain) is all the real numbers between 0 and 6 inclusive.
0.3 miles per minute
1.5 miles in 5 minutes
60 minutes per hour
18 divided by 60 = 0.3
0.3 multiplied by 5 is 1.5
Answer:
1/6 or 1 out of 6
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Given</u>
<u>Find</u> a₁
Use the nth term equation of AP
Apply to the given case and solve for a₁
- - 2 = a₁ + 6(- 1)
- - 2 = a₁ - 6
- a₁ = 6 - 2
- a₁ = 4
