1> distributed
10x - 40 = 20
2 > move - 40 -- + 40
10x = 20 + 40
10x = 60
3 > divide 10
x = 6

Distribute the 5 to the 2x and the negative 8 by multiplying.
10x - 40 = 20
Since 40 is negative, you do the opposite and add 40 to both sides.
10x = 60
Divide both sides by 10.
x = 6
Check by substituting 6 for x.
5 (2(6) - 8) = 20
5 (12 - 8) = 20
5(4) = 20
20 = 20
x = 6

Hope this helps =)

PLEASE HELP ME!! I can’t figure this out
DochEvi [55]
Hello!

The problem has asked that we write a point-slope equation of the line in the image above. Point-Slope Form uses the following formula:

y – y_{1} = m(x – x_{1})

In this case, M represents the slope while X_{1} and Y_{1} represent the corresponding X and Y values of any given point on the line.

We are given that the slope of the line is -\frac{5}{7}. We also know that any given point on a graph takes the form (x,y). Based on the single point provided in the image above, we can determine that X_{1} is equal to 6 and Y_{1} is equal to 2. Now insert all known values into the point-slope formula above:

y – 2 = -\frac{5}{7}(x – 6)

We have now successfully created an equation based on the information given in the problem above. Looking at the four possible options, we can now come to the conclusion that the answer is C.

I hope this helps!

Helppppppp. Find k if the lines 3x-5y=9 & 2x+ky=11 are a)parallel and b)perpendicular
V125BC [204]
For lines to be parallel, they have to have the same slopes. For the equation given as Ax + By + C = 0, the slope is -A / B. Equating the slopes of the given equations of lines,
                                      - (3 / -5) = - (2 / k)
The value of k is equal to -10/3.
