-7x - 9 = - 93

move -9 to the other side

sign changes from -9 to +9

-7x-9+9= -93+9

-7x= -93+9

-7x= -84

divide both sides by -7 to get x by itself

to get +x

-7x/7= -84/-7

answer:

x= 12

Answer:

X=12

Step-by-step explanation:

According to the way I learned it, you would add 9 since you are subtracting it and since it is subtracted, it would be considered a negative number so it would cancel out if you add 9. You would also add 9 to -93 which would give you -84. Bring it down and it will become -7x=-84. Divide both sides by -7, canceling out -7, and -84 divided by -7 is 12. Since they are both negative, you make it positive according to integer rules and therefore, x=12.

What is the equation of the line that passes through the point (6,14) and is parallel to the line with the following equation? y

Gekata [30.6K]

Answer:

$y=\displaystyle-\frac{4}{3}x+22$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept
Parallel lines always have the same slope (m)

Determine the slope (m):

$y=\displaystyle-\frac{4}{3}x -1$

The slope of the given line is $\displaystyle-\frac{4}{3}$ , since it is in the place of m in y=mx+b. Because parallel lines always have the same slope, the slope of a parallel line would also be $\displaystyle-\frac{4}{3}$ . Plug this into y=mx+b:

$y=\displaystyle-\frac{4}{3}x+b$

Determine the y-intercept (b):

$y=\displaystyle-\frac{4}{3}x+b$

To find the y-intercept, plug in the given point (6,14) and solve for b:

$14=\displaystyle-\frac{4}{3}(6)+b\\\\14=-8+b\\b=22$

Therefore, the y-intercept of the line is 22. Plug this back into $y=\displaystyle-\frac{4}{3}x+b$ :

$y=\displaystyle-\frac{4}{3}x+22$

I hope this helps!
