Answer:
The tax amount is 15.17$
The tax rate is 12.4%.
Step-by-step explanation:
First we subtract the cost from the selling price.
137.17 - 122 = 15.17
We have found the tax amount, now for the tax rate.
If tax rate is x, then
122 * x = 137.17
Divide both sides by 122 to get
x = 137.17/122 = 1.124, or .124.
Then convert into percentage by moving the decimal to the right 2 times.
.124 = 12.4%

Answer:
B) 100
Step-by-step explanation:
All 3 interior angles of a triangle add up to 180 so:
x + 25 + 55 = 180
x + 80 = 180
x = 180 - 80
x = 100
Change into slope-intercept form:
y= -3/4x + 5
We will be using the point slope formula to write the perpendicular equation:
y - y1 = m (x - x1)
y + 2 = 4/3(x + 3)
y + 2 = 4/3x + 4
y = 4/3x + 2
Answer:
y = 4/3x + 2
