Solve for m in V = 3x + 2m - y.
jok3333 [9.3K]

Answer:

\large\boxed{m=\dfrac{V+y-3x}{2}}

Step-by-step explanation:

3x+2m-y=V\qquad\text{add}\ y\ \text{to both sides}\\\\3x+2m-y+y=V+y\\\\3x+2m=V+y\qquad\text{subtract}\ 3x\ \text{From both sides}\\\\3x-3x+2m=V+y-3x\\\\2m=V+y-3x\qquad\text{divide both sides by 2}\\\\\dfrac{2m}{2}=\dfrac{V+y-3x}{2}\\\\m=\dfrac{V+y-3x}{2}

Which of the following ordered pairs could represent the y-intercept of a function.
snow_lady [41]
<h3>Answer: (0,5)</h3>

This is because the x coordinate is 0. For any y intercept, the x coordinate is always 0 as this indicates the point is on the y axis.

Contrast this with something like (9,0) and we see that y = 0 indicating this point is an x intercept (it is on the x axis).
