(-4)^-6*(-4)^7 = (-4)^1 = -4
answer a. -4
Just substitute x = 2 and y = 5 into the equation wherever you see x and y.
2 + (12 - 5x) · 2y
2 + (12 - 5(2)) · 2(5)
2 + (2) · 10
4 · 10
40, is the answer which should be the first box.
Here, what you would do is combine like terms. So you get P+2q.
X/200=65/100
200*65=100x
13,000=100x
x=130
