All the second numbers. {0, 2, 6, 7}.
Answer:
The inequality is 
Step-by-step explanation:
Total time:
The total time to complete the test is the sum of the number of multiple-choice questions multiplied by the time it takes to solve each and the number of short-answer questions multiply by the time it takes to solve each.
In this question:
Same number(n) of both.
Multiple-choice takes 2 minutes, short-answer takes 3.5 minutes. The total time is given by:

Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.?
This means that:

So

The inequality is 
You take $18.80 divide by 2 =$9.40 then $18.80+$9.40=$28.20
$28.20 x's 5.5=$$155.10
$18.80 x's 40=$752.00
<span>then add 752.00+155.10=$907.10</span>
The answer is c because scales are usually 2x smaller
slope = m = (y2 - y1)/(x2 - x1)
(y2 - y1)/(x2 - x1) = m
(-1 - 1)/(-1 - x) = 2/7
-2/(-1 - x) = 2/7
2/(x + 1) = 2/7
1/(x + 1) = 1/7
x + 1 = 7
x = 6
Answer: x = 6
