Answer:
y = 3
Step-by-step explanation:
3x - 4y = 12
3(8) - 4y = 12
24 - 4y = 12
- 4y + 24 = 12
- 4y + 24 - 24 = 12 - 24
- 4y = - 12
- 4y ÷ - 4 = - 12 ÷ - 4
y = 3
<em><u>Slope</u></em><em><u>:</u></em> 
<em><u>y - intercept</u></em><em><u>:</u></em> (0, - 3)
Answer:
y = 2/3x - 1
Step-by-step explanation:
Find the slope:
2y = 3x - 5
2/2y = 3/2x - 5/2
y = 3/2x - 5/2
Slope is 3/2
In order for a line to be perpendicular the slope in the equation should be flipped. 3/2 becomes 2/3.
Perpendicular equation:
y = 2/3x + b
b is going to be equal to the y intercept of the point they gave us, so -1.
Answer: y = 2/3x - 1

Answer:
3 days= $105, 6 days= $90, 10 days= $70
Step-by-step explanation:
You can rewrite this equation as y=120-5x
x is the amount of days passed
plug in 3 for x and you get 15. 120-15=105
plug in 6 for x and you get 30. 120-30=90
plug in 10 for x you get 50. 120-50=70
Hope this helps!
