The rational expression will be zero when its numerator is zero and its denominator is NOT zero.  

3x + 15 = 0

3x = -15

x = -5

We check and the denominator 6 - x = 6 - -5 = 11, not zero, good.

Answer: D.  -5

-5 because then the top would be 0 and bottom is 11. 0 divided by anything is 0

5x+10=5(x+2) what is the answer I’ll give u 85 points
asambeis [7]

Answer:

All real numbers of x.

Step-by-step explanation:

5x+10=5(x+2) have the exact same equations on both sides.

5x+10=5x+10

If both are graphed, they will intersect each other for every value of x.

Help with this question!!! ASAP
sergij07 [2.7K]

Answer:Im pretty sure it's quadratic

Step-by-step explanation:

The reason is because if you plot these on a graph they would make a "U" shape witch mean it's a parabola if it were exponential it would not make a "u" shape because it would keep going up and never come back down at a exponential rate.

Using the given points and line, determine the slope of the line. (-3,0) and (2,7)
o-na [289]

Answer:

slope = \frac{7}{5}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (2, 7)

m = \frac{7-0}{2+3} = \frac{7}{5}
