Solve: 1 5 x = -10 A) -50 B) -20 C) -2 D) 2

Inessa [10]

Answer:

In order to find x, you will have to use the operation of equality to isolate the x.

$15x=-10$

Now, use the division property of equality and divide by 15 on both sides. This will cancel out the 15 on the left side of the equation and isolate the x completely.

$-10/15=\frac{-2}{3}$

Thus, this is your answer:

$\boxed{x=-\frac{2}{3} }$

Find the slope of the line containing the two points. (2,5),(-3,-2) Please show work

HACTEHA [7]

Answer:

7/5

Step-by-step explanation:

To solve this problem we will use the formula to find the slope of a line given two points (x₁, y₁), (x₂, y₂)

The formula is:

$m= \frac{y{_2} -y_{1}}{x_{2}-x_{1} } \\\\$

So, we're going to use the points (2,5), (-3, -2) in this formula.

$m= \frac{-2-(5)}{-3-(2)} \\m=\frac{-2-5}{-3-2}\\m=\frac{-7}{-5} \\m=\frac{7}{5}$

Therefore, the slope is 7/5
