Answer:
y = 6x+ 3.
Step-by-step explanation:
y - y1 = m(x - x1)
sub.
distribute.
bring down and solve.
First change the 1/2 to eighths. multiply numerator and denominator by 4.now subtract 4 1/8
I don't know if my answer is completely correct, but I think it's 100. All triangles add up to 180, and an isosceles triangle has 2 equal sides. 40 would be the 2 sides, and 180 subtracted from 80 equals 100.
The perimeter of the rectangle is equal to the doubled sum of the sides, and the area is equal to the product of the sides. So we have the following equation
3 x 2x = 2(3 + 2x)
6x = 6 + 4x
2x = 6
x = 3
If she uses the blue book then she will need,
544/9 ≈ 61 pages
If she uses the red book the she will need,
544/7 ≈ 78 pages
So she will need 17 more pages if she uses the red book.
Hope this helps :)
