X = -4 + e to the sixth power
Hey there...
The correct answer is (C) 105° and here's how I got it.
-3+18x+13+=180° (they are corresponding angles and sum upto 180°)
next step is collecting the like terms so we have 18x+13x-3-3=180°. which is the same thing as 18x+13x-6=180° so you add 6 to both sides and we'll have 18x+13x=186 so we solve for x by adding 18x to 13x which gives 31x then we divide so we have 31x/31=186/31 and x=6.
Plug in the values of x and the equation will give -3+18(6)= 105° and the angle happens to be a vertical angle so B= 105°.
Hope it helps :)
Yes because if you add up all his expenses $92.87+$11.29+$20.00=124.16 which leaves $104.84 (229-124.16=104.84) left and the X-box game only costs $54.99
Answer:
see explanation
Step-by-step explanation:
If f(x) and are inverse functions, then
f()(x) = x
Thus substitute x = (x) into f(x)
f( )
= 5 ( ) - 6
= x + 6 - 6
= x
Thus f(x) and (x) are inverse functions
