The inverse of the funtion <span> f(x) = 4x
</span><span> f(x) = 4x
y = 4x
Swap out x with y
x = 4y
x / 4 = y
y = x / 4
Looks like none of the answer you have given are correct.

Answer:
x = 127 degrees
Step-by-step explanation:
By the external angle of a triangle theorem:-
x + 5 = 79 + m < ACB
m < ACB = 180 - x, so:-
x + 5 = 79 + 180 - x
2x = 79 + 180 - 5 = 254
x = 127 ( answer)
The answer is 40 miles per hour
<u>First we need to find all the interior angles. So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180. </u>
2x + x + 60 = 180
<u>Now lets start to solve. First let's subtract the 60 from both sides. </u>
2x + x = 120
<u>Now we need to add the x's together. </u>
3x = 120
<u>Now we must divide the 120 by 3 to get x by itself. </u>
x = 40
<u>Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so </u><em><u><EHG would be equal to 80. </u></em>
<u>ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do! </u>
