In order to find the value of x, you have to cross multiply both equations. 4x-10 is basically 4 times something subtract 10. Same thing as well for 3x-2. Now it says to find the value of x. X has to also be the same answer for both equation as well. By the way x doesn't have a given number so there is no specific answer.
Answer:
5 cents each
Step-by-step explanation:
1.00 $ is equal to 100 pennies, so 100 ÷ 20 is 5, to check 5 cents times 20 is 100 cents or 1.00 $
Answer:the answer is 44
Step-by-step explanation: cuz 40 divided by 90%= 44
So, we are looking for F of G of 2. So, we need to work backwards and find G(x) first.
![g(-2)=5(-2)+4\\g(-2)=-6](https://tex.z-dn.net/?f=g%28-2%29%3D5%28-2%29%2B4%5C%5Cg%28-2%29%3D-6)
So we know that g(-2) = -6, now we take thatt -6 and plug in into f(x)
![f(g(-2))=f(-6)\\f(-6)=8-10(-6)\\f(-6)=8+60\\f(-6)=68](https://tex.z-dn.net/?f=f%28g%28-2%29%29%3Df%28-6%29%5C%5Cf%28-6%29%3D8-10%28-6%29%5C%5Cf%28-6%29%3D8%2B60%5C%5Cf%28-6%29%3D68)
68 is the answer
