What term can you add to 5/6x-4 to make it equivalent to 1/2x-4?

patriot [66]

$\frac{-1}{3}x$ can be added to $\frac{5}{6}x-4$ to make it equivalent to $\frac{1}{2}x-4$ .

Step-by-step explanation:

Let,

y be the term that can be added to given fraction.

Therefore;

$(\frac{5}{6}x-4)+y=\frac{1}{2}x-4$

Subtracting $\frac{5}{6}x-4$ from both sides to find y

$(\frac{5}{6}x-4)-(\frac{5}{6}x-4)+y=\frac{1}{2}x-4-(\frac{5}{6}x-4)\\\\\frac{5}{6}x-4-\frac{5}{6}x+4+y=\frac{1}{2}x+4-\frac{5}{6}x+4\\\\y=\frac{1}{2}x-\frac{5}{6}x\\\\y=\frac{3-5}{6}x\\\\y=\frac{-2}{6}x\\\\y=\frac{-1}{3}x$

$\frac{-1}{3}x$ can be added to $\frac{5}{6}x-4$ to make it equivalent to $\frac{1}{2}x-4$ .

Answer: Choice B) The graph opens down

The negative 'a' value means the parabola opens downward. One way to remember it is that the positive 'a' value means "happy face" or "smile", and a negative 'a' value means "frowny face".

See the image attachment and note the color coding of the graphs.
