Hello!
First, let's write the problem.
Subtract 10 from both sides.
Divide both sides by 9.
When we got absolute value, we are going to get two results.
and
Let's solve the first one,
Subtract 8 from both sides.
Let's solve the second one.
Subtract 8 from both sides.
Let's combine the ranges.
The attachment shows how would you graph it.
You can feel free to let me know if you have any questions regarding this.
Thanks!

Answer: 143
Step-by-step explanation: So, first, you add the two first amounts, which are $12 and $22, which is 34. Then, you divide the amount you have (4882) by the amount you <em>need</em> (34). And finally, you take away the decimal, and you have your answer!
So the definition of the cosine of an angle of a right triangle is
. You may remember this by SohCahToa (sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, tangent is opposite over adjacent).
Remember, adjacent refers to the side next to the angle in question, and the side can't also be the hypotenuse. The hypotenuse is that longest side and is opposite the right angle.
We have the cosine of 30°. We write
