# solve inequality for the given variable? (answer)

If s + 9 > 24, then you subtract 9 from both sides. You keep the inequality sign facing the same direction. So: s + 9 > 24 => s > 15.

# If f(x) is linearly related to x and f(x+4)-f(x)=32, what is the slopes of the graph of f? (answer)

A slope is a measurement of a change in f(x) over the change in x. f(x+x) - f(x) = 32 tells you two things. First it tells you that the change in x is 4, which is pretty straight forward. The difference between x and x+4 is 4. Secondly, it tells you that the change in f(x) between x and...

# How do I solve this?! (answer)

You have to multiply the first term, -2x, by each of the terms within the parentheses. So it will look like this: -2x*3 - -2x*x, and then you clean it up to: -6x +2x^2 (That's x squared). Notice that the sign in the middle changed because you are subtracting a negative term, which is the...

# Write the slope-intercept equation for the line that passes through (-14, -3) and is perpendicular to -7x – 4y = -4 (answer)

The first step to answering this question is to find the slope of the first line. To do that, we need to put it in slope-intercept form. -7x - 4y = -4  =>  -4y = 7x - 4 => y = (-7/4)x + 1. So the slope of this line is -7/4. Perpendicular lines have a negative reciprocal...
