The correct is this one: "d. 3(9) + 7(5)." Lisa divided the irregular polygon into 2 rectangles with a line. The <span> expression that can be used to find the area of the irregular polygon is 3(9) + 7(5). That will give you the total are of the two rectangles.</span>
Answer:
y²-6
Step-by-step explanation:
(2y-y)(y-6)
= y*(y-6)
= y²-6
Answer:
y = -1/3x + 8
Step-by-step explanation:
If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.
(basically if one is say -2/3, the other is 3/2. just flip it upside down)
So this slope is 3, so the new slope should be -1/3
The equation is now y = -1/3x + b
To find b, substitute (-9,5) in the equation
y = -1/3x + b
5 = -1/3(9) + b
5 = -3 + b
8 = b
So the equation is y = -1/3x + b
