#16: Let's clear the fraction on the way to solving this inequality for x. By mult. the given inequality by 2, we'll get -2 (is greater than) x+4. We want x to be positive. So, leave it where it is. Subtract 4 from both sides of this inequality. We end up with -6 (is greater than) x, which is the same thing as x (is less than) -6. What would the graph of that simple inequality look like?
Graph it. (Hint: The graph is a straight dashed line, and you must shade one side of it, but not the other side.
1 because 1^4-25=-24 which is negative(so below the x-axis)
6n + 15 = -42. If you wish to go further and find n, then subtract 15 from both sides, obtaining 6n = -57, so that n = -57/6.
5,000 I’m pretty positive !
