Answer:
B
Step-by-step explanation:
This is the correct parabola:)
Method 1
we have to calculate the ratio (r) between number of miles ran by Jason, and the number of miles run byMegan.
r=1 mile / (1+1/4) miles
r=1 mile / [(4+1)/4 miles]
r=1 mile / 5/4 miles
r=4/5
Therefore, if Jasen ran 6 miles, we suggest this equation:
6/x=4/5
6*5=4*x
30=4x
4x=30
x=30/4=7.5.
answer: 7.5 miles.
Method 2
f(x)=number of miles ran by Megan.
x=number of miles ran by Jason.
we suggest this function:
f(x)=x+x/4
f(x)=(4x+x)/4
f(x)=5x/4
Then ; if Jason ran 6 miles.
x=6
f(6)=(5*6) /4=30/4=7.5
Answer: 7.5 miles.
Answer:
1) (8,24)
2) (2,6); it represents how she walks 2 steps in 6 feet.
8,160.. but rounding would be 8170 sooo both increased by 5 and 9 percent would be 1270 and 1507 !
