Answer:

B. 24d + 4; $76

Step-by-step explanation:

Part 1: If the online store charges $24 per DVD, this is the same as saying "24 multiplied by the number of DVDs bought".

It's given that "d" represents the number of DVDs

So the first part of the variable expression is: 24d

If the online store also charges an additional $4 per order, that means that it's only $4 extra for the whole order. NOT per DVD you buy.

Result: 24d + 4

Part 2: If someone were to buy 3 DVDs, that would mean that d = 3.

To find the total cost, substitute 3 for d into the expression.

24d + 4
24(3) + 4
72 + 4 = 76
Result: $76

What is the equation in point slope form of the line passing through (0,5) and (-2,11)

IRISSAK [1]

The equation of the line passing through $(x_1,y_1)$ and $(x_2,y_2)$ is

$\frac{x-x_1}{y-y_1} =\frac{x_2-x_1}{y_2-y_1}$ . Here

$\frac{y_2-y_1}{x_2-x_1}$ is the slope of the line.

Substituting numerical values, the equation of the line is

$\frac{x-0}{y-5} =\frac{-2-0}{11-5} \\ \frac{x}{y-5} =-\frac{1}{3} \\ 3x=5-y\\ 3x+y=5$

The equation of the line is $3x+y=5$
