Answer: Parallel: y=-2/7x-2 1/7 Perpendicular: y=7/2x+13
Step-by-step explanation:
2x+7y=14
Subtract 2x from both sides.
7y=-2x+14
Divide both sides by 7 to isolate y.
y=-2/7x+2
Parallel:
Plug in x and y with same slope as the original.
-1=-2/7(-4)+b
Solve for b:
-1=8/7+b
-2 1/7=b
y=-2/7x-2 1/7
Perpendicular:
Plug in x and y with the negative inverse of the original slope.
-1=7/2(-4)+b
Solve for b.
-1=-28/2+b
-1=-14+b
13=b
y=7/2x+13
Add 3 on both sides of the equation
3x=0
divide 3 on both sides of the equation
x=0
Answer:
98 square centimeters
Step-by-step explanation:
first find the area of the non shaded area
8x4=32
next find the area of the rectangle around it
13x10=130
and last you need to subtract the non shaded area from the rectangle around it to find the area of the shaded area
130-32=98
