Mathematics

Answer:

See below.

Step-by-step explanation:

slope of the dotted line: m = (-3 - 5)/(0 - 8) = 1

slope of second line (perpendicular to dotted line): -1

The bold line (second side) has slope -1 and passes through point (-4, 9).

y = mx + b

9 = -1(-4) + b

9 = 4 + b

b = 5

Equation of bold line: y = -x + 5

The third side of the rectangle is parallel to the dotted line and contains point (-4, 9). slope = 1

y = mx + b

9 = 1(-4) + b

9 = -4 + b

b = 13

Equation of third side: y = x + 13

The third side lies on a line that is parallel to the dotted line, so its slope is the same as the slope of the dotted line. The third side contains point (-4, 9). We use the equation y = mx + b and substitute -4 and 9 for x and y, respectively. Then we solve for b.

Trina is purchasing a new bike the store is having 20% off sale and she as 10% coupon of the sale price if the original price of
marusya05 [52]
20% of 89.75 is 17.95
\frac{20}{100}  =  \frac{x}{89.75}  \\ x =  \frac{89.75 \times 20}{100} =  \frac{1795}{100}  = 17.95
so :
89.75 - 19.95 = 71.8
the Trina's coupon will subtract the answer by 10%:

10%of 71.8 is 7.18
\frac{10}{100}  =  \frac{x}{71.8}  \\ x =  \frac{71.8 \times 10}{100}  =  \frac{718}{100}  = 7.18
so the final answer is:
71.8 - 7.18 = 64.62
she has to pay $64.62
hope this helps
