Answer:
A.
Step-by-step explanation:
Perpendicular => so it will have a slope of negative reciprocal to this slope
Slope = 2/3
Now
Point = (x,y) = (6,5)
So,
x = 6, y = 5
Substituting in the slope intercept form
5 = (2/3)(6)+b
5 = 4+b
=> b = 1
So, we have
m = 2/3
b = 1
Putting in the slope intercept equation
y = 2/3x+1

12. Take the percent you pay (100-the discount) as a decimal and multiply it by the regular price.
Step-by-step explanation:
For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22-78. We use this percent byb multiplying the price with a decimal. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.
8. Percent off is 22%. We pay 78%=0.78.
45(0.78)=$35.10
9. Percent off is 33%. We pay 67%=0.67.
89(0.67)=$59.63
10. Percent off is 44%. We pay 56%=0.56.
23.99(0.56)=$13.43
11. Percent off is 75%. We pay 25%=0.25.
279.99(0.25)=$70
