Answer: LAST OPTION.

Step-by-step explanation:

For this exercise you need to use the following formula to find the midpoint:

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Given these points:

$(-8, 5)\ and\ (2, -2)$

You can identify that:

$x_1=-8\\x_2=2\\y_1=5\\y_2=-2$

Then, knowing these values, you can substitute them into the formula shown before:

$M=(\frac{-8+2}{2},\frac{5+(-2)}{2})$

Evaluating, you get that the midpoint is:

$M=(-3,1.5)$

This matches with the last option.

−2(2x+3)≤26 - 2 2 x + 3 ≤ 26 ?

SashulF [63]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

$- 2 ( 2 x + 3 ) \leq 26.$

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$- 2 ( 2 x + 3 ) \leq 26$

Divide both sides by -2. We know that since 2 is negative, it'll be < (less than) 0. So, the direction of inequality will change.

$2x+3\geq \frac{26}{-2} \\$

Divide 26 by -2..we'll get the answer as -13.

$2x+3\geq -13$

Now, subtract 3 from both the sides.

$2x\geq -13-3$

Subtracting -13 by 3..we'll get the answer as -16.

$2x\geq -16$

Divide both sides by 2. We know that since 2 is positive, the direction of inequality will remain the same.

$x\geq \frac{-16}{2} \\$

Divide -16 by 2..we'll get the answer as -8.

$\huge \boxed{ \boxed{ \bf \: x\geq -8 }}$

The correct answer is ⇨ x greater than or equal to -8.

SOMEONE PLEASE HELP MEE

Answer:

The missing numbers are 12 and 39 respectively

Step-by-step explanation:

From the table, we can see that the ratio of the left column to the right is 3/5

So at any point in time, the values on a particular row of the table must conform

to this ratio

In other light, we have to multiply what we have on the left by 5/3 to get what’s on the right

and we have to multiply what we have on the right by 3/5 to get what’s on the left

We have this as follows;

20 * 3/5 = 12

and;

65 * 3/5 = 39
