Find an equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0)
Anna007 [38]

The equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0) is 8x -3y = -16

<h3>Equation of a straight line</h3>

From the question, we are to determine the equation of the line parallel to the given equation and that passes through the given point

Lines that are parallel to each other will have the same slope.

First, we will determine the slope of the line in the given equation.

The given equation of the line is

8x − 3y = 1

Express the equation in the slope-intercept form of a line, y = mx + b

Where m is the slope and

b is the y-intercept

That is,

8x − 3y = 1

8x -1 = 3y

3y = 8x - 1

y = 8/3(x) - 1/3

By comparing,

∴ The slope of the line is 8/3

Since we are to find the equation of a line parallel to this, the slope of the line will also be 8/3

Now, find the equation of a line containing the point (-2, 0) and that has  a slope of 8/3

Using the point-slope form of a line

y - y₁ = m(x - x₁)

x₁ = -2

and y₁ = 0

∴ y - 0 = 8/3(x - -2)

y = 8/3(x +2)

3y = 8(x +2)

3y = 8x + 16

8x -3y = -16

Hence, the equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0) is 8x -3y = -16

Celeste wants to have her hair cut and permed and also go to lunch. She knows she will need $68. The perm costs twice as much as
Nezavi [6.7K]
Let P=Perm cost
Let H = Haircut cost
Let L = Lunch cost

Perm costs twice as much as haircut so.. P = 2H
L = 5

H + P + L = 68 the total cost is $68

H + 2H + 5 = 68 since P = 2H and L=5

3H + 5 = 68

3H =63

H = 63/3

H = 21

A Haircut is $21
Perm = 2H = 2(21) = $42

Joe earns $425 a week for working 40 hours and an additional $20 an hour for each hour over 40. Last week, Joe made $485. Write
Tasya [4]

Answer:

Joe worked 3 hours overtime.

Step-by-step explanation:

Let t = number of hours overworked

425 + 20 × t = 485

425 + 20t = 485

20t = 485 - 425

     = 60

\frac{20t}{20} = \frac{60}{20}

t = 3

\therefore Joe worked 3 hours over time.

Hope this helps :)
