Answer:y=4 x=3
Step-by-step explanation:9(-9+3y)-4y=11
-81+27y-4y=11 23y=92 y=4 x=3
When 2 lines are coinciding, this means its the same line.
One equation is simply a multiple of the other.
8x = 4x*2
This means the multiplier is 2
5y*2 = 10y
8*2 = 16
The missing values are 10y and 16
Xintercept is something of the form (x, 0)
So if y=0 then -4x-3=0; -4x=3; x= -3/4
X intercept is (-3/4,0)
The area of the irregular shape is the area of the two rectangles added together. Use the measure calculate feature of Geometer's Sketchpad to add the areas. The perimeter of the irregular shape is equal to the sum of the six segment around the outside of the figure.
