Solve this equation: $45 - ($2.75/pen)x = $12. Simplifying, we get
$33 = ($2.75)x, so that
x = $33 / ($2.75) = 12.
Tim's buying 12 pens leaves him with $12.
Answer:
5
Step-by-step explanation:
u can add 2 and 3 when their base number (3) are the same
The statements about the function that are true are
- The vertex of the function is at (–3,–16).
- The graph is increasing on the interval x > –3.
- The graph is positive only on the intervals where x < –7 and where x > 1.
<h3>How to interpret the graph?</h3>
The equation of the graph is given as
f(x) = (x - 1)(x + 7)
The graph of the function is added as an attachment
On the graph, we have
Vertex = (-3, -16)
This is so because the graph has a minimum point of (-3, -16)
Also, the graph crosses the x-axis at x = 1 and x = -7
This means that the graph is positive at x >1 and x >-7
Because the vertex is a minimum, the graph is increasing at the left of its symmetry i.e. x > -3

Answer: d) 2730
<u>Step-by-step explanation:</u>
1st movie and 2nd movie and 3rd movie
15 videos × 14 remaining videos × 13 remaining videos = 2730
So all you have to do is times
x 13 and 1/3 which is the same as 1/4 x 40/3 which is equal to 40/12 = 3 1/3mile
