Given that 7x – 2y = 30
weeeeeb [17]

Answer:

x=32/7

Step-by-step explanation:

7x-2(1)=30  Plug in 1 as y and simplify.

7x-2=30     Add 2 on both sides of the equation.

  <u>+2 +2</u>

7x=32         Divide both sides of the equation by 7.

<u>/7   /7</u>

x=32/7

Hope this helps...have an amazing day (。・∀・)ノ゙

Given: WZ is perpendicular to VY, WZ bisects VY, VZ = 2x+2, and ZY = 3x-4
Annette [7]

Answer:

  28

Step-by-step explanation:

  VZ = ZY

  2x +2 = 3x -4

  6 = x . . . . . . . . add 4-2x to both sides

  VZ = 2x +2 = 2(6) +2 = 14

Now we can find VY.

  VY = VZ + ZY = 14 + 14 . . . . . . VY is the total of the two halves

VY = 28

Which of the following equations is equivalent to
andrew-mc [135]

Answer:

B. y=3x+12

Step-by-step explanation:

Hi there!

We want to find out which equation is equivalent to -6x+2y=24

The equation is currently written in standard form, which is ax+by=c, where a, b, and c are integer coefficients, but a and b CANNOT equal zero

We can change the equation into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, as all of the answer options are in slope-intercept form.

To do that, we'll need to isolate y by itself on one side

So let's add 6x to both sides to remove it from the left side

-6x+2y=24

+6x        +6x

__________________

     2y=6x+24

Now divide both sides by 2 to get the value of y by itself (1y)

y=3x+12

The answer is B. y=3x+12

Hope this helps!
