Store A is cheaper than B
The way to solve is pretty simple for B.
You have to divide the cost by the number of tubes.
So in this case:
9/3=3
15/5=3
21/7=3
See the pattern?
So the cost per lip gloss is $3.
Now for Store A:
Just divide 5.50/2
The answer is 2.75
Compare both numbers

2.75<3.00
So, store A is cheaper.

Quick algebra 1 question for 50 points!

Answer:

b. -x + y = 0

Step-by-step explanation:

Direct variation:

Direct variation means "y varies directly as x”:

$y \propto x \implies y=kx$

where k is the (non-zero) constant of variation.

To determine which of the given equations represents a direct variation, isolate y for each and compare with the direct variation equation.

Equation a

$y=\dfrac{4}{3}x-2$

This is not a direct variation equation as there is an addition of -2.

Equation b

$-x+y=0$

$\implies y=x$

This is a direct variation equation where the constant of variation is 1.

Equation c

$xy=8$

$\implies y=\dfrac{8}{x}$

This is not a direct variation equation as y is inversely proportional to x.

Equation d

$y=14$

This equation does not include the variable x, and so is therefore not a direct variation equation.
