Answer:
a.
500x+0.04=y
400x+0.05=y
for percentages move decimal to the left twice
They are both isosceles triangles
You just solved it.... do u need the work shown?
Answer:
you switch 8x and 4y by subtracting 8x to 4y + 16 and substracting 4y to 8x.
This gives you the equation -4y = -8x+16
Then you divide each side by -4
To give you your slope-intercept form which is y = 2x-4.
The length is 10
The width is 4
4 + 6 = 10
4 x 10 = 40
