If y = 10, then -8y2 = -8(10)2 = -800.
8y squared + 52y - 180
The answer depends on the value of y. For example, when y = 0, 8y2 + 6y - 2 = -2 when y = 1, it is 12

If y = 2, then 8y = 8 x 2 = 16.
It is 8y - 8.
8y squared + 52y - 180
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
-16
0
It is (8*10^0)*y.
-6
The answer depends on the value of y. For example, when y = 0, 8y2 + 6y - 2 = -2 when y = 1, it is 12
There were five lizards and five spiders. x+y=10 4x+8y=60 x=10-y 4(10-y)+8y=60 40-4y+8y=60 40+4y=60 4y=20 y=5 x+5=10 x=5
-8x-8y=-64 -8y=8x-64 y=-x+8
(8x-8y)/(8x+8y) = (x-y)/(x+y)Cancel down by 8; you have simplified the equation.

If y = 2, then 8y = 8 x 2 = 16.
