Answer:

11 + 2x

Step-by-step explanation:

In algebra, like terms are terms that have the same variables (letter after the number). Like terms can be combined for example the 6 and 5 have the same variable (none) so they can be combined. IMPORTANT! While we do combine the 2x and the 4x since the 2x came after a minus sign we consider it a negative, so -2x + 4x (or 4x - 2x) is 2x NOT 6x

Question 1:

Price per milliliter

Small $4.50 / 250ml

Medium $9.95 / 500 ml

Large $16.95 / 1000 ml

Question 2:

$9.95 / 500 ml > $4.50 / 250ml > $16.95 / 1000 ml

Question 3 - 4:

$4.50 / 250ml = ($4.50 * 6) / (250ml * 6 ) = $27 / 1500ml = 0.018

$9.95 / 500 ml = ($9.95 * 3) / (500 ml * 3) = $29.85 / 1500ml = 0.019

$16.95 / 1000 ml = ($16.95 * 3) / (1000 ml * 3) = $50.85 / 1500ml = 0.0339

( Use the first one for question 3 and the second for question 4)

$4.50 / 250ml would be the cheapest way to get 1500ml.

$9.95 / 500ml would be the most expensive way to get 1500ml.

I hope this helps you! Tell me if I'm wrong!

Question 27 of 28<br> 1 Point<br> What is the slope of the line shown below?<br> (3,-2)<br> (2,-4)
Gwar [14]

Answer:

The slope is 2

Step-by-step explanation:

To find the slope given two points, we use the formula

m = (y2-y1)/(x2-x1)

   = (-4--2)/(2-3)

   = (-4+2)/(2-3)

   = -2/-1

   = 2
