We know the y intercept is 16 because y=16 when x=0.
Find slope by calculating change in y over change in x.
(12-16)/(2-0)
-4/2
-2
Plug both values into slope intercept form. y=mx+b where m is slope and b is the y intercept.
Final answer: y=-2x+16
Answer:
do the following
Step-by-step explanation:
subtract the 2nd equation from the 1st....
x-2y = 14
-(x+ 3y = 9)
______________
-5y=5
y= -1
since you know that y is = to - 1 pick the 3rd answer
First you can solve the triangle. complete the triangle my making the final side which would equal 12 because the top and bottom are bith 6. and the bottom is 12 then you do 1/2(12)(12) to find the area which would be 72. the area of the rectangle would be 18 so the total would be 90ft^2 when you add them together
