3 0

For this, we are just going to plug in -9 for every x and then solve the equation:


q(x)=7x^{2} -1


q(-9)=7(-9)^{2} -1


q(-9)=7(81)-1


q(-9)=566


Now we know that q(-9) is equal to 566.

15x+12(10-x)=141<br>make sure to use steps to solve!​
goldfiish [28.3K]

Answer: x=7

Step-by-step explanation: First you distribute the 12 to (10-x). That then gives you 15x+120-12x=141. Now you combine like terms. So you do 15x-12x=3x. Your new equation now is 3x+120=141. Subtract 120 from 141 and mark it out. That leaves you with 3x=21. Divide both sides by 3. Your final answer is x=7.
