Let 's' be the allowed speed.
If the maximum speed is 70 and the minimum is 40, we know 's' is between these two values inclusively, i.e. 40 ≤ s ≤ 70
*Remember for inequality symbols, whether strict or inclusive, the term on narrow side is "less than" the term on the broad side
The correct answer is <u>D) P = 2 · 12 + 2 · 7</u>

This is the concept of arithmetic:
Given that Carol ran a total 1 3/4 miles for 5 days last week, the total distance covered was:
Total distance=(distance per day)×(total number of days)
=1 3/4×5
=7/4×5
=35/4
=8 3/4 miles
Total distance ran this week is:
Total distance=(2 1/4×4)
=9/4x4
=9 miles
therefore we conclude that the distance covered this week was greater than the distance covered last week.
b] this distance was greater by:
difference=(distance covered this week)-(distance covered last week)
=9-35/4
=(36-35)/4
=1/4
the answer is 1/4 miles
The y-intercept is (0,-11), which is option C.
Answer:
26x-67-x²
Step-by-step explanation:
We are given
Expanding (x-8)²=x²-16x+64
10x-3-(x²-16x+64)
10x-3-x²+16x-64
26x-67-x²
