$6(2u +2)+ 7u+3 = 6(u+5) -2u\\\\\implies 12u +12 +7u+3 = 6u+30-2u\\\\\implies 19u +15 = 4u +30\\\\\implies 19u -4u = 30 -15\\\\\implies 15u = 15\\\\\implies u =\dfrac{15}{15} =1$

Answer:

$\:\mathrm{First\: problem:\:}-2,\\\:\mathrm{Second\: problem:\: }-3$

Step-by-step explanation:

The slope of a line passing through points $(x_1, y_1)$ and $(x_2, y_2)$ is:

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

Plugging in any two points in the table we have:

First problem:

$m=\frac{1-5}{2-0}=\frac{-4}{2}=\fbox{$-2$}$

Second problem:

$m=\frac{-1-5}{2-0}=\frac{-6}{2}=\fbox{$-3$}$

Write a linear equation in standard form that crosses (4, -3) and (-2, 9):

kirill115 [55]

Slope =(9+3)/(-2-4) = 12/-6 = -2
Y+3 = -2 (×-4) => y=-2×+5
D is the line asked
Slope: -1/3
D: y-6 = -1/3 (×-3) or y= -1/3× + 7
