Which technique is most appropriate to use to solve each equation? Drag the name of the technique into the box to match each equ

faltersainse [42]

(x + 3) (x + 2) = 0
To solve it, the most appropriate technique is:
1.) zero product property
The solutions are:
(x + 3) = 0
x = -3
(x + 2) = 0
x = -2

x² + 6 = 31
To solve it, the most appropriate technique is:
2.) square root property
x² = 31-6
x² = 25
x = +/- root (25)
x = +/- 5
The solutions are:
x = 5
x = -5

If you were to write the equation of this line in the form y=mx+c what is the value of m

marusya05 [52]

Answer:

B choice.

Step-by-step explanation:

The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.

It is very obvious to tell because of steepness. Low steepness = low value

High steepness = high value.

We can also find the slope by using rise/run.

$m = \frac{dy}{dx}$

The change of y over the change of x.

Given the coordinate points (0,1) and (4,0). Both points are part of the graph.

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

$m = \frac{1 - 0}{0 - 4} \\ m = \frac{1}{ - 4} \\ m = - \frac{1}{4}$

Therefore the value of m is - 1/4
