Researchers collected data from a group of people who completed 30 minutes of moderate exercise based on their age, The table and
scatterplot show each person's age and the maximum heart rate in
beats per minute (bpm) each person reached while exercising,

A. h(x)=2.9x-250
B. h(x)=4.2x-276
C. h(x)=-2.9x+250
D. h(x)=-4.2x+276

I think its C h(x)=-2.9x+250

Step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
