Answer:

9 (m+5)-3(m-2)=8m+31

9m+45 - (3m + 6)= 8m+31

9m+45-3m-6=8m+31

45-6+31=8m-9m+3m

70=2m

m=70/2

Therefore m = 35

Hope u understood.............

Answer:

m = 10

Step-by-step explanation:

9(m+5) - 3(m-2) = 8m+31

(9m+45) - (3m-6) = 8m+31

9m+45-3m+6 = 8m+31

9m-3m+45+6 = 8m+31

6m+51 = 8m+31

8m+31 = 6m+51

8m = 6m+51-31

8m+6m = 51-31

2m = 20

m = 20÷2

m = 10

What system of equations is shown on the graph below?

erma4kov [3.2K]

Answer:

The equation of the line passing through the points (-2,0) and (0,-4)

$\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1}$

$\frac{y - 0}{x - ( - 2)} = \frac{ - 4 - 0}{0 - ( - 2)} = \frac{ - 4}{2} = - 2$

$y = - 2(x + 2) \\ y = - 2x - 4$

$2x + y = - 4$

The equation of the line passing through the points (0,-2) and (4,0)

$\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1} \:$

$\frac{y - ( - 2)}{x - 0} = \frac{0 - ( - 2)}{4 - 0}$

$\frac{y + 2}{x} = \frac{1}{2}$

$x - 2y = 4$

Option B

x minus 2 y = 4 and 2 x + y = negative 4
