Answer:
m=10
Step-by-step explanation:
Use elimination method - I am eliminaing the y-variable.
1(5x + 8y = 16) → 5x + 8y = 16
4(6x - 2y = 54) → 24x - 8y = 216
Add equations: 29x = 232
Divide by 29: x = 8
Answer: x = 8
Answer:
1) 0.75
2) y = 
x - 3
3) (4, 0); (0, -3)
Step-by-step explanation:
Convert to slope-intercept form (y = mx + b) by solving:
y = x - 3
m is the slope, so or you can write as 0.75.
To find the x and y intercepts, set the y value to zero and solve (x-intercept), and b is the y-intercept.

since your finding retail price u need to do 10×.7 and that would be 7 then and the 7 to 10
Answer:
-2
Step-by-step explanation:
- 5x + 8 = 18
Take + 8 to the right hand side, it turns negative i.e -8
-5x = 18 - 8
-5x = 10
Divide both sides by the coefficient of x which is -5
-5x/5 = 10/-5
x = -2
