Answer:

Step-by-step explanation:

First, subtract 4 from both sides. When you do this, that leaves you with: 3x=9. Then, divide 9 by 3 to get x by itself. x=3

---------------------

Let's solve for k.

3kx+24=9x

Step 1: Add -24 to both sides.

3kx+24+−24=9x+−24

3kx=9x−24

Step 2: Divide both sides by 3x.

3kx / 3x = 9x−24 / 3x

k = 3x−8 / x

Answer:

k = 3x−8 / x

-----------------------------------

Let's solve for x.

3kx+24=9x

Step 1: Add -9x to both sides.

3kx+24+−9x=9x+−9x

3kx−9x+24=0

Step 2: Add -24 to both sides.

3kx−9x+24+−24=0+−24

3kx−9x=−24

Step 3: Factor out variable x.

x(3k−9)=−24

Step 4: Divide both sides by 3k-9.

x(3k−9) / 3k−9 = −24 / 3k−9

x = −8 / k−3

Answer:

x = −24 / 3k−9

Use the slope formula to find the missing coordinate: R(0,_), S(-4,2) m=5

Delicious77 [7]

Answer

The missing value is 22

step-by-step explanation

The slope formula is

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

From the question,

m=5

$x_2=-4$

$y_2=2$

and

$x_1=0$

We substitute these values to get,

$5= \frac{2 - y_1}{ - 4- 0}$

Simplify

$5= \frac{2 - y_1}{ - 4}$

$5 \times - 4=2 - y_1$

$- 20=2 - y_1$

$- 20 - 2=- y_1$

$22= y_1$

$y_1 = 22$

The missing value is 22
