Answer:
The sandals cost before tax $25.
Step-by-step explanation:
Let us assume that the sandals cost before tax $x.
So, after giving an 8% tax the price will be 
.
If the $15 gift certificate on that after tax price and the final cost of the sandals becomes $12, then
1.08x - 15 = 12
⇒ 1.08x = 27
⇒ x = $25
Hence, the sandals cost before tax $25. (Answer)
Your answer is going to y = lx + 4l + 2
Answer: 1/3
Step-by-step explanation:
- Two points on this graph are (40, 80) and (70, 90). These points can be used to find the slope.
- The formula for slope is (y2-y1)/(x2-x1).
- Plugging our numbers into the formula:
- (80-90)/(40-70) = (-10)/(-30) = 1/3

Answer:
2x +5y = -15
Step-by-step explanation:
We need to find the slope
m = (y2-y1)/(x2-x1)
= (-7--1)/(10- -5)
= (-7+1)/(10+5)
-6/15
-2/5
The point slope form
Y+7=
-2/5 (x - 10).
Distribute
y + 7 = -2/5x + 4
Add 2/5 x to each side
2/5x +y +7 = 4
Subtract 7 from each side
2/5x +y = -3
Multiply each side by 5
5(2/5x +y) = -3*5
2x +5y = -15
This is standard form Ax + By = C where A is a positive integer
