Find the equation of the line that is perpendicular to the line y = 4 and passes through the point (-2, 1).
mojhsa [17]

Answer:

x = - 2

Step-by-step explanation:

y = 4 is the equation of a horizontal line parallel to the x- axis.

Thus a perpendicular line will be vertical and parallel to the y- axis.

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (- 2, 1) with x- coordinate - 2, thus

x = - 2 ← equation of perpendicular line

The amount of revenue in dollars, y, that Makayla receives from selling x posters is given by the equation y = 3x. The cost of p
d1i1m1o1n [39]

Answer:

75 posters

Step-by-step explanation:

Given

y = 3x ----  Revenue

y = \frac{x}{3} + 200 --Cost of production

Required

Determine the number of posters that when cost equals revenue

To do this, we simply equate both equations

i.e. 3x = \frac{x}{3} + 200

Collect like terms.

3x - \frac{x}{3} = 200

Multiply through by 3

3(3x - \frac{x}{3}) = 200*3

9x - x = 600

8x = 600

Divide both sides by 8

\frac{8x}{8} = \frac{600}{8}

x = \frac{600}{8}

x = 75
