Answer:y=2x+7

Step-by-step explanation:

so for the new equation, we know the slope is going to be the same (because its parallel) so for starters we have y=2x+b so now in order to find b (the y-intercept) we have to plug the point into the equation. So it would look like -1=2(-4)+b and then you solve for b and get 7 for b. SO the final answer is y=2x+7.

What is the equation of the line x–3y=18 in slope-intercept form? Drag and drop the appropriate number, symbol, or variable to e
Sunny_sXe [5.5K]
Simple...

you have: x-3y=18

You want to convert it into slope-intercept form or y=mx+b form-->>>

x-3y=18

Isolate the variable-->>

x-3y=18
-x      -x

-3y=-x+18

Now simply divide...

\frac{-3y}{-3} = \frac{-x+18}{-3}

y=\frac{1}{3}x -6

Thus, your answer.

The function y=e−3x is vertically stretched by a factor of 4, reflected across the y-axis, and then shifted up 5 units, find the
olya-2409 [2.1K]

Answer:

Step-by-step explanation:

y = e^(-3x)

Stretch by factor of 4

y = 4e^(-3x)

Reflect across y axis

y = 4e^(3x)

Shift up by 5

y = 4e^(3x) + 5

2x = 4x - 8 show work
Marianna [84]

Answer:

x = 4

Step-by-step explanation:

2x = 4x - 8

<em>subtract 2x from both sides of the equation</em>

2x - 2x = 4x - 2x - 8

0 = 2x - 8

<em>add 8 to both sides of the equation</em>

0 + 8 = 2x - 8 + 8

8 = 2x

<em>divide both sides of the equation by 2</em>

8/2 = 2x/2

4 = x

Please help me its very urgent!​
marusya05 [52]

Answer: A

Step-by-step explanation:

This is because...

1st. Simplify both sides of the equation (distribute the 4 and combine like terms)

6 + -x = 20 + 4x + -4 (distributed 4)

-x + 6 = 4x + 16 (combined like terms)

2nd. Subtract 4x from both sides.

3rd. Subtract 6 from both sides.

4th. Divide both sides by -5.
