A) (0, 2)
B) (3, 0)
C) (0, 0)
D) (0, 3)
Solution of inequality is determined by the fact that if the given point is in the shaded region of the graph or not . Dotted line in the graph shows that any point on that dotted line is not part of the solution . So here all those options which have the points in the shaded region but not on the line are solutions .
Therefore only C (0,0) is the correct option .

Shakira went bowling with her friends .she paid $3 to rent shoes and then $4.75 for each game of bowling.if she spent a total of $21 , then how many games did shakira bowl ?
Answer: Shakira bowled 4 games.
Step-by-step explanation:
Hi, the total cost for Shakira (21) is equal to the multiplication of the price of each game of bowl (4.75) and the number of games bowled (g), plus the cost of the shoes rental (3).
3 + 4.75 g = 21
Solving for g:
4.75 g = 21-3
4.75 g = 18
g= 18/4.75
g = 3.78 = 4 games (rounded)

The school gym can hold no more than 650 people. The bleachers will seat 176 people. The PTA is setting up 25 rows of chairs for their meeting. At most, how many chairs can be in each row?
A) 18
B) 19
C) 26
D) 27
Answer:
A)18
Step-by-step explanation:
The number of chairs in the school gym can be represented by inequality 176 + 25c ≤ 650, where c represents the number of chairs in each row. When you solved for c, we find that c = 18.96. Since you cannot have a fraction of a chair, we know that the maximum number of chairs in each row must be 18.

Xavier worked 10 hours on Monday and 15 hours on Wednesday. His total pay was 280.00 what is his rate per hour
Xavier's rate per hour is $11.20.
What is unit rate?A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, Xavier worked 10 hours on Monday and 15 hours on Wednesday. His total pay was 280.00
Number of hours worked on Monday = 10 hours
Number of hours worked on Tuesday = 15 hours
Total pay received by Xavier = $280
Total number of hours worked = (10 + 15) = 25 hours
Therefore, Rate per hour = 280/25 dollars per hour
Hence, Xavier's rate per hour is $11.20.

Which graph represents the equation y=13x−4 ?
Answer: The correct option is graph (A).
Step-by-step explanation: We are given to select the graph that represents the following linear equation :
[tex]y=\dfrac{1}{3}x-4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
Comparing with the slope-intercept form y = mx + c of a straight line, we see that
the slope of the line (i) is [tex]m=\dfrac{1}{3},[/tex] and y-intercept, c = -4.
Also, we know that the slope of a line passing through the points (a, b) and (c, d) is given by
[tex]m=\dfrac{d-b}{c-a}.[/tex]
Graph (A) :
The points (0, -4) and (3, -3) lies on the line. So, its slope will be
[tex]m=\dfrac{-3-(-4)}{3-0}=\dfrac{1}{3},[/tex]
the point where the line crosses the y-axis is (0, -4).
That is, y-intercept, c = -4.
Since the slope and y-intercept of graph (A) is same as that of line (i), so this option is CORRECT.
Graph (B) :
The points (0, -2) and (3, -3) lies on the line. So, its slope will be
[tex]m=\dfrac{-3-(-2)}{3-0}=-\dfrac{1}{3},[/tex]
Since the slope of graph (B) is not same as that of line (i), so this option is NOT CORRECT.
Graph (C) :
The points (0, -4) and (-3, 3) lies on the line. So, its slope will be
[tex]m=\dfrac{3-(-4)}{-3-0}=-\dfrac{7}{3},[/tex]
Since the slope of graph (C) is not same as that of line (i), so this option is NOT CORRECT.
Graph (D) :
The points (-4, 0) and (-3, 3) lies on the line. So, its slope will be
[tex]m=\dfrac{3-0}{-3-(-4)}=\dfrac{3}{1}=3,[/tex]
Since the slope of graph (B) is not same as that of line (i), so this option is NOT CORRECT.
Thus, graph (A) is the correct option.

The expression 60(1+x) represents the total bill including the tip. What do the different parts of the expression represent? Match each expression to the correct description.
1) Cost of meal __
2) Tip percentage __
3) Number of friends __
a) x
b) (1+x)
c) 60
Answer:
1) Option c
2) Option b
3) Option a
Step-by-step explanation:
Given : The expression 60(1+x) represents the total bill including the tip.
To find : What do the different parts of the expression represent?
Match each expression to the correct description.
1) Cost of meal __
2) Tip percentage __
3) Number of friends __
Solution :
The expression represents the total bill including the tip is 60(1+x).
When we see the expression,
The cost of the mean is always fixed.
So, Cost of the meal is 60.
Number of friends is unknown.
So, Number of friends is 'x'.
The tip percentage is given by '1+x'.

A movie theater charges $10.50 per ticket and $5 per bucket of popcorn. You never buy the popcorn because you think it's too expensive.
Is the total price you pay proportional to the number of tickets you buy?
Yes, the total price pay is proportional to the number of tickets.
What is proportionality?In mathematics, proportionality indicates that two quantities or variables are related in a linear manner.
Since you never plan to buy the popcorn but only the movie ticket, therefore we can definitely say that there is a direct correlation between the total price and the number of tickets bought.
Since, 1 ticket = $10.50
So,
The proportion equation is:
P = 10.50 t
where P is the total price and t is the number of tickets
Hence, the total price pay is proportional to the number of tickets.

A teacher wants to calculate a class average on the last test. One student made a significantly lower score than the rest of the class because he failed to follow instructions. Which measure of center would be best for the teacher to use to get an accurate idea on how well the class as a whole performed on the last test?
A. mode
B. median
C. mean
D. range
Final answer:
The median is the best measure of center for the teacher to use to evaluate the overall performance of the class on a test when the data set includes an outlier.
Explanation:
The most appropriate measure of center for the teacher to use in this situation is the median. This is because the median is the best measurement when a data set contains outliers or extreme values that could significantly skew the mean. Since the dataset contains a student score that is significantly lower due to not following instructions, the median would provide a more accurate idea of how the class as a whole performed, as it is less affected by this outlier. On the other hand, the mode might not be as informative if most of the scores are unique, and the mean would be substantially affected by the low score. The range is a measure of spread, not center, and therefore not suitable for determining the average performance.
