SOLUTION:
We are to calculate the shaded area of the given shape.
CONCEPT:
This is a triangle that a rectangle was cut out from.
To calculate the shaded area of the given shape, we are to find the area of the triangle and then subtract the area of the recangle that was cut out.


The shaded area = Area of the triangle - Area of the rectangle
Answer:
y = -6/5x +4
Step-by-step explanation:
6x+5y=20
Subtract 6x from each side
6x -6x+5y=20 -6x
5y = 20 -6x
Divide each side by 5
5y/5 = 20/5 -6x/5
y = 4 - 6/5x
We usually write the variable first
y = -6/5x +4
Answer: a = -3
Step-by-step explanation: First we distribute the -2 to a and -3 to get -2a+6=12, then subtract 6 on both sides, -2a=6, finally divide by -2 on each side to get a = -3.
