Answer:
y(x) = -2x -8
Step-by-step explanation:
using the hint, insert the points (x,y) in the equation:
-2 = -3m + b eq1
2 = -5m + b eq2
eq2 - eq1 :
4 = -2m ==> m = -2
insert m in eq1:
-2 = -3*(-2) +b ==> b = -8
Answer:
The answer is C. a = -4,000 m
Step-by-step explanation:
If you subtracted 31,000 from 35,000, you would get 4,000 in a minute. Do the same for the rest, you would also get 4,000 m in a minute, so the answer would be a = -4,000 m
Answer:
1. y = -3x + 5
2. y = 1/4x - 2
Step-by-step explanation:
y=mx+b
1. 5 = -3(0) + b, so b = 5
y = -3x + 5
2. (-2-(-1))/(0-4) = -1/-4 = 1/4
-2 = 1/4(0) + b, so b = -2
y = 1/4x - 2
Answer:
$121.5
Step-by-step explanation:
Given data
costs of phone = $150
discount= 25%
tax= 6%
amount of discount
= 25/100*150
=0.25*150
=$37.5
amount of tax
= 6/100*150
=0.06*150
=$9
amount payable
=150-37.5+9
=$121.5
Hence he will pay $121.5
