Answer: x= -7

Step-by-step explanation: subtract 4x on both sides. That leaves you with -9=3x+12. Then subtract 12 on both sides. From there you have -21=3x. Divide by 3, and your answer is negative 7

Write an equation of the line with the given properties. Your answer should be written in standard form.
Vanyuwa [196]

Given:

The slope of the line is m=0.

The line passes through the point P(-9,-3).

To find:

The equation of the line in standard form.

Solution:

Standard form of a line is:

Ax+By=C

The slope intercept form of the line is

y-y_1=m(x-x_1)

Where, m is the slope and (x_1,y_1) is the point on the line.

It is given that the slope of the line is 3 and it passes through the point (-9,-3), so the equation of the line is

y-(-3)=0(x-(-9))

y+3=0

y=-3

Therefore, the standard form of the given line is y=-3.

Which expression is equivalent to (7x – 5) – (3x - 2)
Nastasia [14]

Answer:

D

We have the expression

(7x-5)-(3x-2)

First we need to distribute the negative throughout the parenthesis. Then we can combine like terms in order to simplify this expression

(7x-5)-(3x-2)\\\\7x-5-3x+2\\\\4x-3

This answer matches D.
