Answer:

Revenue and Expense = $230

No. of attendees: 10

Step-by-step explanation:

Let n be the no. of attendees

Expense = 50 + 18n

Revenue = 23n

Break even when:

50 + 18n = 23n

50 = 5n

n = 10

23n = 230

Decide whether the graphs of the given euqations are parallel perpendicular or neither
DIA [1.3K]
<h3>Answer: C) perpendicular</h3>

Explanation:

Each equation given to you is in y = mx+b form (aka slope intercept form).

The slope m is what we'll focus on.

The first equation has slope of 1, while the second equation has slope -1.

The two slopes multiply to -1. This is a property of any pair of perpendicular lines, as long as neither line is vertical nor horizontal.

Or you could note that -1 is the negative reciprocal of 1, or vice versa.

So there are a few options to see why the lines are perpendicular.

Answer:

Slope = \frac{1}{5}

Equation of the line is y=\frac{x}{5}

Step-by-step explanation:

Given question is incomplete; find the complete question in the attachment.

Since the given line passes through two points (5, 1) and (10, 2),

Slope of the given line = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}

m = \frac{(2-1)}{(10-5)}

m = \frac{1}{5}

Since the given line passes through (10, 2), equation of the line will be

y - y' = m(x - x')

y - 2=\frac{1}{5}(x-10)

y=2+\frac{x}{5}-2

y=\frac{x}{5}

Therefore, equation that can be used to find the distance y from the start after x minutes will be y=\frac{x}{5}
