Answer:
Step-by-step explanation:
plot an open circle on the 4 and a closed circle on the 10. Then draw a line that goes from 4 to 10.
20 * .10 = 2 <em>(2 = 10% of 20)</em>
20 + 2 = 22
20 x .07 = 1.4 <em>(1.4 = 7% of 20)</em>
20 + 1.4 = 21.4
The price of a 20$ haircut with a 10% tax would be $22.
The price of a 20$ haircut with a 7% tax would be $21.40.

Answer:
A) 3y = x + 16
Step-by-step explanation:
The equation of a perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The constant will be chosen to match the given point.
Swapping coefficients, we get ...
-3y = x + c
Negating the y-coefficient gives ...
3y = x + c
Filling in the given point, we have ...
3(5) = -1 + c
16 = c
The equation of the perpendicular line can be written as ...
3y = x + 16 . . . . matches choice A
_____
Note that choice A is the only equation that gives a line with positive slope. The given equation has negative slope, so its perpendicular must have positive slope.
