For x = -1, 3(-1) - 5y = 9 => -3 - 5y = 9 => 5y = -3 - 9 = -12 => y = -12/5 = -2.4
for x = 0, 3(0) - 5y = 9 => -5y = 9 => y = 9/-5 = -1.8
for x = 1, 3(1) - 5y = 9 => 3 - 5y = 9 => 5y = 3 - 9 = -6 => y = -6/5 = -1.2
Answer: 13%
Step-by-step explanation:
Given : A piece of luggage sells for $225.00 it is on sale this week for $195.00 .
Decrease in price = $225.00-$195.00= $30.00
Formula to find the percent decrease :-
![\dfrac{\text{Decrease in price}}{\text{Previous price}}\times100\\\\=\dfrac{30}{225}\times100=13.3333333333\approx13\%\ \ [\text{Rounded to the nearest whole percent.}]](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BDecrease%20in%20price%7D%7D%7B%5Ctext%7BPrevious%20price%7D%7D%5Ctimes100%5C%5C%5C%5C%3D%5Cdfrac%7B30%7D%7B225%7D%5Ctimes100%3D13.3333333333%5Capprox13%5C%25%5C%20%5C%20%5B%5Ctext%7BRounded%20to%20the%20nearest%20whole%20percent.%7D%5D)
Hence, the percent decrease = 13%
If l || m than 8x+20=11x-31

Answer:
105°
Step-by-step explanation:
First, we get the area of the whole rectangle, easy enough:
18 * 16 = 288 cm²
Now, for the area of the circle, we use the circle area formula:
Area = pi * r²
Area = 3.14 * 6² = 3.14 * 36 = 113.04cm²
Now we substract the circle area from the rectangle area:
Shaded region = 288 - 113.04 = 174.96cm²
