Answer:
Market price $400
Cost price $300
Step-by-step explanation:
MP: market price
CP: cost price
1. (MP x 0.9) - CP = 60
CP = 0.9MP - 60
2. MP - CP = 100
CP = MP - 100
0.9MP - 60 = MP - 100
MP - 0.9MP = 100 - 60
0.1MP = 40
MP = 400
Cost price = MP - 100 = 400 - 100 = 300
Answer:
y = 2x + 0 or y = 2x
Step-by-step explanation:
use slope-intercept form
12 - 10 = 2
6 - 5 = 1
m value = 2/1 = 2
y=2x+b
to find b plug one of the points in for x and y
Example: 10 = 2(5) + b
solve equation
10 = 10 + b
subtract 10 from both sides
0 = b
Equation of line equals y=2x+0 or simply just y=2x
Answer:
option D or y = 7x + 2 is the answer
HA + bA = 2
A(h+b) = 2
A = 2/h+b
