1) consider the expression x^2-b. what has to be true about the values of b for this expression to be
factorable?
2)write an equation of a radical (square root symbol) that has the starting point (vertex) of (5,-2).
3) if we aren't careful we would take x/x and simplify it to be 1. if you graph y =x/x it may look like a straight
line, but what is "missing on your graphing calculator?

answer: the four apples you took away.

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

x< -17/2 hope this
