The Division Property of Equality would be used here.

It states that both sides of an equation can be divided by a number not equal to zero and still be equivalent. Both sides of -3x = 252 can be divided by -3 and still be equivalent.

By the way,  x = -84!

Answer:

See Below.

Step-by-step explanation:

We are given that ∠1 and ∠7 are supplementary.

And we would like to prove that a is parallel to b.

  Statements:                                           Reasons:

\textbf{\textsf{1. $\angle 1$ and $\angle 7$ are supplementary}}              Given

\textsf{2. $m\angle3$ + $m\angle 7$ $= 180$}                               Supplementary Angles

\textsf{3. $\angle3$ and $\angle7$ are supplementary}                Definition of Supplementary

\textsf{4. }\bf{\angle 1 \cong \angle3}                                               Congruent Supplements Theorem

\textsf{5. }a\parallel b                                                      Corresponding Angles Converse

And we are done!

A given line has the equation 10x+2y=-2.
Iteru [2.4K]

The equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

If two lines are parallel then their slopes are equal.

We have the following line:

10x + 2y = -2\\2y = -10x-2\\y = -5x-1

Thus, the slope of the line is -5.

Therefore a parallel line is of the form:

y = -5x + b

We replace the point (0,12)

12 = -5 (0) + b\\12 = b

Finally, the equation is of the form:

y = -5x + 12

Answer:

5x + y = 12
