[1] The median to the base passes through the top point (0,b) and the bottom point (0,0) since it is going straight down. The slope formula is
\frac{y_2-y_1}{x_2-x_1}
So, the slope of the median is (b-0)/(0-0) = b/0. Technically, this is undefined, but let's leave it this way for now.

[2] The base passes through the left point (-a,0) and the right point (a,0). Its slope must be (0-0)/(a-(-a)) = 0.

[3] We now check if the slopes are negative reciprocals. Flipping b/0 over and putting a negative sign gives:
b/0 -> - 0/b = 0
So the slopes are negative reciprocals, which means the lines are perpendicular.

Rock singer and writer Beep Blair is paid 11.5% on her CD sales and music downloads. Last year, she sold 1.22 million CDs and 2.
Dmitrij [34]

Using proportions, it is found that she earned $943,000 from CD sales.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The total amount involved in the sells and downloads are:

1.22 x 5 + 2.1 x 1 = 8.2 million.

She was paid 11.5% of that, hence:

0.115 x 8.2 = 0.943 million = $943,000.

She earned $943,000 from CD sales.

How many solutions are there to the equation below?
Anvisha [2.4K]

We will see that the equation has only one solution, so the correct option is B.

<h3>How many solutions an equation has?</h3>

For an equation of the form:

p(x) = C

Where p(x) is an expression that depends on x, and C is a constant.

The solutions are all the values of x that make the equality true.

For our case, we have:

x = -5

Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:

-5 = -5

So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.
