x^2+7x=4

Take the coefficient of x

Divide by 2

Please help?? ??????

Given:

Given that the graph of a line with coordinates (-3,2) and (0,-2)

We need to determine the slope of the line parallel to the given line.

Slope:

The slope of the line can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the coordinates (-3,2) and (0,-2), we have;

$m=\frac{-2-2}{0+3}$

Simplifying, we get;

$m=-\frac{4}{3}$

Thus, the slope of the given line is $m=-\frac{4}{3}$

Slope of the parallel line:

The parallel lines always have the same slope.

Thus, the slope of the parallel line is $m=-\frac{4}{3}$

Hence, the slope of the parallel line is $m=-\frac{4}{3}$

Therefore, Option c is the correct answer.

Factor completely. 5x^2-20x+20=5x 2 −20x+20

Harman [31]

Step-by-step explanation:

5x^2 - 20x + 20 = 5x^2 - 20x + 20

5(x^2 - 4x + 4) = 5(x^2 - 4x + 4)

(5 + 5) (x^2 - 4x + 4)
