I am attaching the full question...
Because AB is parallel to CD, the transversal line EF creates the same angles in AB and CD.
This means that 3x+40 = 4x
..........==>> x = 40 degrees

You reflect a function with respect to the
axis by changing its sign.
In fact, if you consider the two alternatives
and 
you can see that you're choosing opposite outputs for the same inputs.
In other words, one graph will be made of points like
, the other of points like 
And the transformation

is exactly a reflection with respect to the
axis.
Her next step is to find a common denominator. Remember that if you multiply a number to the denominator, you'll have to multiply it to the numerator too:
1/3(4/4) + 1/4(3/3)
4/12 + 3/12
Simplify. Combine like terms
4/12 + 3/12 = 7/12
7/12 will be final solution
hope this helps
Answer:
d is the answer
Step-by-step explanation:
Well, seeing the information above, he used 5/8 of paint to paint the fence and table top. If he only had 1/8 left of the paint, he used 2/8 on the chair.
I found the 5/8 because I needed a common denominator. I multiplied the top and bottom by 2 to get 2/8. 3/8+2/8=5/8, and then I added 2/8 to the 5/8 that then gave me 7/8 of paint used, and 1/8 of paint left.
Hope I helped!
