Answer:
1) On the x-axis, the arm span is plotted. On the y-axis, the height is plotted. It is chosen to be that way because the numbers on that have been assigned on the x-axis increase and decrease in a small amount, while the numbers on the y-axis increase and decrease in a huge amount.
2) (lolz i cant show u my work but i will try my best with explanations even tho ian allat.) So, Using the slope formula, I got a the equation y=x+15. The equation was determined with the formula m=y2-y1/x2-x1. The points that were used included (37,40) and (47,50). After finding the slope, I did the best guess for the y-intercept, which is known as b in y=mx+b.
3) The slope of the line represents the time it takes for the arm span and the height. The y-intercept represents the height that the arm span starts developing or gets bigger.
4) It fits perfectly
5) The data is pretty inconsistent.
6) About 68-69 inches tall
7)About 71-72 inches wide
yeo u had my brain work after this

the answer is x >0 hope this helped
Answer:
for the second space add a zero then multiply 5x5 and 5x2 add that and move the decimal 2 places to the left its infront of your addition answer.
Step-by-step explanation:
The class is made up of male and female students.
"A drama class has a total of 26 students"
f + m = 26
"The number of females is 16 less than the number of males"
f = m - 16
Substitute the second equation into the first.
m - 16 + m = 26
- combine like terms -
2m - 16 = 26
- add 16 to both sides -
2m = 42
- divide by 2 -
m = 21
Now substitute that answer into either equation
f + 21 = 26
- subtract both sides by 21 -
f = 5
Remember that whatever you do to one side, you have to do to the other
