Step-by-step explanation:
Let's represent the number of mochas bought with the variable
, and the number of lattes bought with the variable
.
Since there are
students, the total number of mochas and lattes bought must be
. This can be represented with the following equation:

We can also set up another equation based on the total amount spent on the coffe:

If we rearrange the first equation, we can solve for
:

If we substitute this into the second equation, we can solve for
:





Subtituting this back into the original equation, we can solve for
:



Therefore, 9 mochas and 14 lattes were bought.
Answer:
the top one, (-1,3)
Step-by-step explanation:
Answer:
500 ≤ 260 + 6x
240 ≤ 6x
40 ≤ x
x is the number of minutes you can use per day.
Answer:
f(x)g(x) = 2x² - 6x
General Formulas and Concepts:
<u>Algebra I</u>
- Expand by FOIL-ing (First, Outside, Inside, Last)
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x
g(x) = x - 3
<u>Step 2: Find f(x)g(x)</u>
- Substitute: f(x)g(x) = 2x(x - 3)
- Distribute 2x: f(x)g(x) = 2x² - 6x
