-20=4x-4
solve for x
simplify your answer as much as possible

Answers

Answer 1

Answer: x = -4

Step-by-step explanation:

so, we first move the terms.

-4x = -4 + 20

then, we just calculate that.

-4x = 16

finally, simply divide both sides.

x = -4

Answer 2
Answer: x = -4

Step by step

4x – 4 = –20

4x = – 20 + 4

4x = –16

x = –16/4

x = –4

What are the slope and the y-intercept of the graph of the linear function shown on the grid?

Answers

Answer:

C

Step-by-step explanation:

Slope=rise/run

Y intercept is the where the line hits the y axis which is -1.5

Answer:

Slope: -1/4

y-intercept: -1.5

Step-by-step explanation:

First you do rise over run meaning you from the point (-2,2) you rise up 2 to reach the x axis which is where point -6,0 so you rise 2 points and run 6. since the line is negative it becomes -1/4 and y-intercept is where the line first touches the y-line which is -1.5. I hop this helps!

What value of Y makes the equation true ?

Answers

Answer:

y = -5/2 or -2.5

Step-by-step explanation:

3y + 4 = -y - 6

add y to both sides

4y + 4 = -6

subtract 4 from both sides

4y + 4 - 4 = - 6 - 4

4y = -6 - 4

4y = -10

divide both sides by 4

4y/4 = -10/4

y = -10/4

y = -5/2 or -2.5

Find the function value: f(0.5) if f(x) = 8x - 12

Answers

x = 1.6

f = 0.5

0.5(x) = 8x -12

0.5x= 8x -12

subtract 8x from both sides

-7.5x = -12x

Divide by -7.5x, both sides

X=1.6

For the future, know that the slope of horizontal lines is always zero and the slope of vertical lines is always undefined.
