#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.

What is the product (9t-4)(-9t -4)

Hey Tro2,

Lets find the product of your equation together,

The question we are encountering is : What is the product (9t-4)(-9t-4)?

Lets simplify this step by step, shall we.

$\left(9t-4\right)\left(-9t-4\right)$ : Equation

$\mathrm{Distribute\:parentheses\:using}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$ .

Where : $a=9t,\:b=-4,\:c=-9t,\:d=-4$ .

This leads to $9t\left(-9t\right)+9t\left(-4\right)-4\left(-9t\right)-4\left(-4\right)$ .

Now we have to $\mathrm{Apply\:minus-plus\:rules}$ .

Where: $-\left(-a\right)=a,\:\:\:\:+\left(-a\right)=-a$

$-9t\cdot \:9t-9t\cdot \:4+4\cdot \:9t+4\cdot \:4$

$=-81t^2+16$
