Answer: Ethan will have to spend 2 hours reading if 14 pages are left to read
Step-by-step explanation:
Given the equation
P=-30h+74
where p =number of pages left to read and
h= the number of hours he has spent reading
Therefore , if Ethan has 14 pages left to read, then the number of hours Ethan will have to read will be
P=-30h+74
14= -30h + 74
30h= 74-14
30h= 60
h = 60/30
h =2 hours
Ethan will have to spend 2 hours reading if 14 pages are left to read
Answer:
undefined
0
Step-by-step explanation:
The formula for slope is
m = (y2-y1)/ (x2-x1)
We have points
(-7,2) (-7,-7)
m = (-7-2) /(-7--7)
= -9/(-7+7)
= -9/0
This is undefined
We have points
(-8,-3) (6,-3)
m = (-3--3) /(6--8)
= (-3+3/(6+8)
= 0/14
