Answer:
-62
Step-by-step explanation:
Plug 27 into the equation
a27=-10+(27-1)(-2)
27-1=26
26 times -2 = -52
-52-10=-62
50 + 0.50m = 0.70m
50 = 0.70m - 0.50m
50 = 0.20m
50 / 0.20 = m
250 = m......the plans will cost the same at 250 miles <==
50 + 0.50(250) = 50 + 125 = 175
0.70(250) = 175
and they would both cost $ 175 <==
Answer:
y - 14.95 = 18.075(x-1)
Step-by-step explanation:
If an internet company charges $14.95 per month and a setup fee, then we can say
1 month = $14.95
If the total cost for 9 months is $159.55
Then we can write both cases as a coordinate (1, 14.95) and (9,159.55)
The equation of a line in point slope form is expresses as
y-y0 = m(x-x0)
Find the slope m
m = 159.55-14.95/9-1
m = 144.6/8
m = 18.075
Substitute m = 18.075 and any of the coordinate in the equation to have;
Using the coordinate (1, 14.95)
y - 14.95 = 18.075(x-1)
Hence a linear equation in point-slope form that model the situation is y - 14.95 = 18.075(x-1)
