Answer:

x = -1

Step-by-step explanation:

3x - 5 = - 8 (6 + 5x)

3x - 5 = - 48 - 40x

3x + 40x = - 48 + 5

43x = - 43

x = - 43/43

x = - 1

Answer:

y = -2x + 6 and y = 1/3x - 7

Step-by-step explanation:

For A, using rise over run, you can count 2 units up and 1 unit left of any given point to get to the next point. Because left is the negative direction on a graph, the 1 unit is negative. To calculate slope, divide the rise (2) over the run (-1) and substitute the slope as m into y = mx + b. In the formula, b is the y-intercept (where the line crosses the x axis). The y-intercept of A is 6, so replace b in the formula with 6:

y = -2x + 6

The slope of B is 1/3 and the y intercept is -7, so substitute those values into the formula again to get the answer for B:

y = 1/3x - 7

Mo bisects lmn m lmn 6x-28 m lmo x+34. find m
garri49 [273]
LMO+NMO = LMN,
x+34 + NMO = 6x-28
But, MO bisects LMN, so LMO=NMO
x+34 + x+34 = 6x-28
2x+68 = 6x-28
4x = 96
x = 24
That would makem it
24 + 34 =58 T NMO = 6(24)-28
58 + nmo = 144 - 28 = 119
116- 58 = 58
