This is a Desmos question please help me

B

Step-by-step explanation:

If the 2 lines were parallel, then

5x - 10 = 70 ( alternate angles )

Add 10 to both sides

5x = 80 ( divide both sides by 5 )

x = 16

For the 2 lines to be parallel then x = 16

B.16

Step-by-step explanation:

First I would Make an equation:

For example set (5x-10)=70

Add 10 to both sides:

5x-10+10=70+10

Simplify:

5x=80

Divide both sides by 5:

5x/5=80/5

simplify:

x=16

In conclusion the answer is B.16

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
