Answer:
82 m should be correct i hope
Step-by-step explanation:
The equation for point-slope is y-yi=m(x-xi).
In your given problems, you would use the given coordinate and plug in the x for xi and the y coordinate for yi. The y and x are left alone ( this is how you solve for y=mx+b).
Ex. #1: (2,2) m=-3
Equation: y-yi = m(x-xi)
y-2 ( y coordinate) = -3(x-2)(the x coordinate).
Simplify y-2 = -3x+6 —> y=-3x+8
First, we want to find the difference in monthly fee and per minute costs.
20 - 15 = 5
0.25 - 0.05 = 0.20
So basically we now know that we need to make up for 5 dollars of monthly cost difference, and for every minute we talk with the two plans at the same time, it's different by 0.20.
Now, we just can divide 5 dollars by the difference of 0.20, which you would get 25 minutes from.
So you would have to talk for 25 minutes for the two plans to be the same cost.
Assuming that you used them at the same time, not just used B or A.
Answer:
what is the rest of your qustion
Step-by-step explanation:
Answer:
Its is a linear y= -2
Step-by-step explanation:
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be
0 or 1 for each of its variables. In this case, the degree of variable y is 1
