Solve for zzz. 42=-7(z-3)42=−7(z−3)
xxTIMURxx [149]

Answer:

False

Step-by-step explanation:

Well to solve for z we single it out, distribute, use the communicative property, and combine like terms.

42 = -7(z - 3)42 = -7(z - 3)

Distribute

42 = -7z + 21*42 = -7z + 21

42 = -7z + 882 = -7z + 21

-42 to both sides

-7z + 840 = -7z + 21

-21 to both sides

-7z + 819 = -7z

+7z to both sides

819 = 0

<em>Thus, </em>

<em>the given equation is false.</em>

<em>I hope this helps :)</em>

What is the slope for 2x-1=-3y
dexar [7]

Answer:

The slope is -2/3

Step-by-step explanation:

It is recommended to solve for 'y' variable the equation given, this means, leave the 'y' variable alone in one side of the equation. Doing that, leaves us the following:

y=\frac{-2}{3}x +\frac{1}{3}

This is the general equation of a line: y=mx+b where 'm' is the slope (by comparison), thus We have the desired result
