Answer: 3.5 Miles
Step-by-step explanation: It would take her 8.5 min to run one mile because 51/6 is 8.5. Then I divided 30 by 8.5 to get 3.52, which is rounded to 3.5 miles in 30 min
Hope this helps :)

To find this you first have to find the f(x) values for x = 5 and x = 8
x = 5
f(x) = 5^2 + 6(5) + 11
f(x) = 25 + 30 + 11
f(x) = 66
x = 8
f(x) = 8^2 + 6(8) + 11
f(x) = 64 + 48 + 11
f(x) = 123
Then you subtract the two from each other to see how much it has changed in those 3 numbers.
123 - 66 = 57.
Then you take that answer and divide it by the change in x (which is 3)
57/3 = 19
Answer:
y=3x+15
Step-by-step explanation:
y2-y1 6 - 3 3
_____= _______= ______= 3
x2- x1 -3 + 4 1
y - y1 = m(x - x1)
= y -6 = 3( x + 3)
= y -6 = 3x + 9
= y = 3x + 15
