Answer:

B) 6

Step-by-step explanation:

3(6) + 8 = 26

18 + 8 = 26

26 = 26

I don't know that method they are referring to. Seems pointless.

Typically, you would just set that equation up like:

3n + 8 = 26

- 8 -8

3n = 18

3n/3 = 18/3

n = 6

30. Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

tamaranim1 [39]

Equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.

Step-by-step explanation:

We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

The formula used for point-slope form is:

$y-y_1=m(x-x_1)$

We are given slope m = 4/5

Point (-7,9) where x₁ = -7 and y₁ = 9

Putting values in the formula:

$y-y_1=m(x-x_1)\\y-9=4/5(x-(-7))\\y-9=4/5(x+7)$

So, equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.
