Answer:
4
Step-by-step explanation:
The cost for plan 1 will be ...
p1 = 10 +5x
The cost for plan 2 will be ...
p2 = 30
These costs are equal when ...
p1 = p2
10 +5x = 30
5x = 20 . . . . . . . . subtract 10
x = 4 . . . . . . . . . . . divide by 5
The two plans will cost the same if a customer borrows 4 DVDs in a month.
In order to have average 80 score from 5 tests, student needs to have 400 points (80%*500=0.8*500=400)
So far he has 63+72+88+91= 314
400-314=86
He needs to get 86 points from the last test.
Since he is obviously getting better at tests, i think he'll manage :)
Answer:
y=-1/3x-5
Step-by-step explanation:
y=mx+b is equation of line where m is slope and b is y-intercept.
From question statement, we observe that
m= -1/3 , b= -5
put above values in equation of line, we get
y= -1/3x-5.
Answer:
-5
Step-by-step explanation:
As, x = - 1
So 2(-1)-3 = - 2 - 3 = - 5
So y = - 5
