<h2>Hello!</h2>

The answers are:

1 $x=-20$

2 $x=-9$

3 $x=-5$

4 $r=-2$

5 $x=-4.5$

<h2>Why?</h2>

To know the solution of the problems, we need to isolate each variable.

Remember that:

- If we have an equality: if the number is subtracting (negative sign), and if you need to move it to the other side of the equality, its sign changes to positive.

- If we have an equality: if the number is adding (positive sign), and if you need to move it to the other side of the equality, its sign changes to negative.

- If we have an equality: if the number is part of a product , and if you need to move it to the other side of the equality, the same number will be dividing the factors of the side. On the opposite, if the number is dividing, it will be multiplying on the other side of the equality.

So,

1 - Solving for "x"

$\frac{4}{5}x=-16\\x=\frac{-16}{\frac{4}{5} }=-16*\frac{5}{4}=-20\\x=-20$

2 - Solving for "x"

$-3x+4=31\\-3x=31-4=27\\x=\frac{27}{-3}=-9$

3 - Solving for "x"

$2x+(-12)=-22\\2x-12=-22\\2x=-22+12=-10\\\\2x=-10\\x=\frac{-10}{2}=-5$

4 - Finding the solution

$25=15-5r\\25-15=-5r\\-5r=10\\r=\frac{10}{-5}=-2$

5 - Finding the solution

$12.5+5x=-10\\5x=-10-12.5=-22.5\\5x=-22.5\\x=\frac{-22.5}{5}=-4.5$

Have a nice day!

Find the equation of line that contains point (2,9) and is parallel to the line y=-5x+7?

kotegsom [21]

Answer:

y = -5x + 19

Step-by-step explanation:

Note that the equation of any line parallel to y= -5x+7 has the same form as y= -5x+7, but a different constant. Knowing that this new line passes thru (2,9), we determine the value of this constant as follows: 9 = -5(2) + C, or 9 = -10 + C. Then C = 19, and the equation of this new line is

y = -5x + 19

Rewrite the following equation in slope-intercept form. 5x + 7y = 7 Write your answer using integers, proper fractions, and impr

pogonyaev

Answer:
y = (-5/7) x + 1

Explanation:
The slope-intercept form of the line has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
5x + 7y = 7

To put this in slope-intercept form, we will need to isolate the y as follows:
5x + 7y = 7
7y = -5x + 7
y = (-5/7) x + (7/7)
y = (-5/7) x + 1
where:
m is the slope = -5/7
c is the y-intercept = 1

Hope this helps :)
