Answer:

It does not.

Step-by-step explanation:

$6(2x - 6) = -7(-2x + 4); \\ 6 * 2x - 6 * 6 = -7 * (-2x) + (-7) * 4; \\ 12x - 36 = 14x - 28; \\ 14x - 12x = -36 + 28; \\ 2x = -8; \\ x = -4.$

$\{-4\}$ is our set of solutions. Answering your question, it does not.

7. The points (3,5) and (2, y) are on a line with a slope of 3. Find y.

PtichkaEL [24]

Answer:

We get value of y: y = 2

Step-by-step explanation:

The points (3,5) and (2, y) are on a line with a slope of 3. Find y.

We can find y using formula of finding slope of a line.

The formula is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We have $x_1=3, y_1=5, x_2=2, y_2=y$ and Slope = 3

Putting values and finding y

$Slope=\frac{y_2-y_1}{x_2-x_1}\\3=\frac{y-5}{2-3}\\3=\frac{y-5}{-1}\\-1(3)=y-5\\-3=y-5\\y=-3+5\\y=2$

So, we get value of y: y = 2
