Step-by-step explanation:
Partial and negative tickets cannot be sold, so the minimum number values of e and s are 0. If s = 0, then e = 16, and if e = 0, then s = 20. Therefore, the values of s are whole numbers from 0 to 20 and the values of e are whole numbers between 0 and 16. The greatest number of student tickets sold was 20 and the greatest number of nonstudent tickets sold was 16.
B) 2x − 3y < 7
C) −3x + 2y > 7
D) 3x − 2y < 7
Answer:
D) 3x − 2y < 7
Step-by-step explanation:
We note that the x- and y-intercepts are about 2.3 and -3.5, respectively.
In "intercept form," the equation of the line can be written ...
x/x-intercept +y/y-intercept = 1
Using the given intercepts, this is ...
x/2.3 +y/(-3.5) = 1
The answer choices suggest that we should multiply this by 7. When we do, we get ...
3x -2y = 7 . . . . the equation of the boundary line
__
The next trick is to figure the comparison symbol. We note that x-values are less than those on the line, and y-values are greater than those on the line. It is convenient to consider the term with a positive coefficient, so we don't get confused with minus signs and reversed comparisons.
As we said, x-values are less than those on the line, so the shaded area is ...
3x -2y < 7 . . . . matches choice D
Answer:
D) 3x − 2y < 7

Answer:
The graph is shown in attachment.
Step-by-step explanation:
we have to draw a graph of the inequality
3x+2y>-5
The following steps are:
Step 1: Rearrange the equation such that "y" is on the left side and rest on the right.
3x+2y>-5
⇒ ⇒
Step 2: Plot the line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
. Here, dashed line is drawn.
Step 3: Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
The graph is shown in attachment.
Answer:
The length is 15 and the width is 20
Step-by-step explanation: 10 times 5 is 50 and 6 times is 300 which is the area you are looking for. 15 times 20 is 300 and you add 5 to each numbers so it works.
