Hey there!

4(x + 5) = 12

4(x) + 4(5) = 12

4x + 20 = 12

SUBTRACT 20 to BOTH SIDES

4x + 20 - 20 = 12 - 20

CANCEL out: 20 - 20 because it gives you 1

KEEP: 12 - 20 because it help solve for the x-value


NEW EQUATION: 4x = 12 - 20


SIMPLIFY IT!

4x = -8

DIVIDE 4 to BOTH SIDES

4x/4 = -8/4

CANCEL out: 4/4 because it gives you 1

KEEP: -8/4 because it gives the x-value


NEW EQUATION: x = -2


Therefore, your answer is s x = -2


Good luck on your assignment & enjoy your day!

Answer:

x = -2

Step-by-step explanation:

you need to use the distribution property first!

4(x + 5) = 12 ------> 4x + 20 = 12

now you need to subtract 20 from both sides so that you can isolate x

4x = -8

finally, divide -8 by four so that x is alone, meaning solve to find x!

x = -2

Answer:

Middle School In Favor: 25%

Middle School Not in Favor: 75%

High School In Favor 20%

High School Not In Favor 80%

Step-by-step explanation:

For the middle school in favor, we need to find the percent, which is 50 out of 200, so its 1/4, 25%

So the rest of the middle school is not in favor, which is 75%

High school is 60 not in favor, so we need to find the percentage. So 60 out is 300 is 20%

And we just subtract 20 from 100 which leaves us with 80

Find the equation of the line specified. The line passes through the points ( -2, 3) and ( -4, 7)
cestrela7 [59]

Answer:

y=-2x-1

Step-by-step explanation:

Let the first coordinate point be (x_1,y_1) and the second coordinate point be (x_2,y_2)

So

x_1 = -2

y_1 = 3

x_2 = -4

y_2 = 7

Now we can use the formula for equation of line to figure it our.

Equation of line formula is  y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Plugging in the known values and arranging in slope-intercept form, we have:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\y-3=\frac{7-3}{-4-(-2)}(x-(-2))\\y-3=\frac{4}{-2}(x+2)\\y-3=-2(x+2)\\y-3=-2x-4\\y=-2x-4+3\\y=-2x-1

This is the equation of the line passing through the points ( -2, 3) and ( -4, 7)
