F(x) =x^2+6x and g(x)=7-x find (f-g)(x) and (f-g)(9)
liq [111]
(f-g)(x) = x²+6x - (7-x)
(f-g)(x) = x² + 6x - 7 + x
(f-g)(x) = x² + 7x - 7

(f-g)(9) = 9² + 7*9 - 7
(f-g)(9) = 81 + 63 - 7
(f-g)(9) = 137

How in the heck do I do this?​
Fudgin [204]

The measure of a triangle is 180 degrees. In other words the sum of the angles of a triangle is 180 degrees

To solve for x set all of the expressions of angles equal to 180 and isolate x

11x - 3 + 7x + 5 + 13x - 8 = 180

31x + (- 6 + 6) = 180 + 6

31x/31  = 186 / 31

x = 6

To find the measure of each angle plug 6 into the x into each individual expression

Hope this helped!
