Answer:
5 is the answer.
Step-by-step explanation:
y= 4x-1
taking derivative with respect to x ,we get
Using distance formula
we have points
at x =-3 the value of y = 4(-3)-1= -12-1 = -13
at x =2 the value of y = 4(2)-1 =7
points are ( -3,-13) and (2,7)
distance formula =
=
=
=
=5
Answer:
yes
Step-by-step explanation:
Answer: 133 minutes
Step-by-step explanation:
Hi, to answer this question we have to write an equation for the cost of each company:
The cost is equal to the fixed fee (40) plus the product of the cost per minute talking on the phone (0.25) and the minutes spent talking in the phone in the month (m)
40 + 0.25 m
The cost is equal to the fixed fee (60) plus the product of the cost per minute talking on the phone (0.10) and the minutes spent talking on the phone in the month (m)
60+ 0.10m
- Since both costs must be equal:
40 + 0.25 m = 60+ 0.10m
Solving for m:
0.25m-0.10m = 60-40
0.15m = 20
m = 20/0.15
m= 133.34 minutes
= 133 minutes (rounded)
Answer:
the slope is 11 and the y intercept is 6 m=11 b=6
15 cause u will multiple then divide from each to get a good answer
