Answer:

x = -4 and x = 5

Step-by-step explanation:

Since $x^2 + 2x$ and $3x + 20$ both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.

$x^2 + 2x = 3x + 20$

Now we solve the equation.

$x^2 + 2x = 3x + 20$

$x^2 - x = 20$

$x^2 - x - 20 = 0$

$(x + 4) (x - 5) = 0$

$x + 4 = 0 ; x -5 = 0$

$x = -4 ; x = 5$

jeka57 [31]

Answer:

Yes it has a slope which is undefined

Step-by-step explanation:

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

Answer:

The answer to your question is x-axis, y-axis

Step-by-step explanation:

To answer this question just remember the equation of the slope

m = $\frac{y2 - y1}{x2 - x1}$

Then:

If the numerator is zero, the line is parallel to the x-axis and the slope will be zero.

If the denominator is zero, the line is parallel to the y-axis and the slope will be undefined.
