Answer:

Given information :

f(x) = 2x^2-2x+7\\g(x) = x^2+9x-6

Find f(x) - g(x)

f(x)-g(x) = (2x^2-2x+7) - (x^2+9x-6)

Distribute the negative to the second polynomial

f(x)-g(x)=2x^2-2x+7 -x^2 -9x + 6

optional : rearrange the terms

f(x)-g(x)=2x^2-x^2-2x-9x+7+6

Combine like terms and find f(x) - g(x)

f(x)-g(x) = x^2 - 11x + 13

MVUT =175, mVUJ=17x-3, and mJUT=17x+8. Find x
kotykmax [81]
The diagram of the three angles is shown below with point U as the point where all three lines meet.

Angles property: Angles around a point add up to 360°

We set up an equation

175+17x-3+17x+8=360
180+34x=360
34x=360-180
34x=180
x= \frac{180}{34}= \frac{90}{17}

Answer: 13/20 of the video games at both of their houses.


Step-by-step explanation: The equation is 1/4 + 2/5. You need to find their common denominator which is 20, so the equation is now 5/20 + 8/20 = 13/20, which can't be simplified.
