Answer:
48-20x=21
Step-by-step explanation:
So, we basically have to clear the fractions (get rid of the denominators)
Multiply everything by the LCM of 6 and 8 (24)
24(2)-24(5/6x)=24(7/8)
48-20x=21
Hope this helps!

Answer: graph D
<u>Step-by-step explanation:</u>
graph A) The equation is y = x
graph B) The equation is y = -x² + 2
graph C) The equation is x = y²
graph D) The equation is y = 2
Which equation does not have an "x" in it? <em>D</em>
Therefore, the y-value is not dependent on an x-value.
