Answer:
range is -3, 5.9 , 8.3
Step-by-step explanation:
{(3.2, –3), (7.6, 5.9), (1.4, –3), (–9.1, 8.3)}
We are given with set of ordered pairs (x,y)
In each ordered pair, x is the domain and y is the range
for domain , take all the x values (first number) from the ordered pairs
for range, take all the y value (second number) from the ordered pairs
y values of the ordered pairs are -3, 5.9, -3, 8.3
So range is -3, 5.9 , 8.3
Answer:
{(3.2, –3)}
Step-by-step explanation:
The domain is the set of all the values of
x .The range is the set of all the values of y .
Domain: { 3.2 , 7.6 , 1.4 , − 9.1 }
Range: { − 3 , 5.9 , 8.3 }

Thank you!
In this question, we create a system of inequalities to describe the possible number of hours and distance you may have to drive. It is not possible to have driven 160 miles.
Part A:
Let t represent the number of hours you drive and d represent the distance you drive.
The constraints for the number of hours are: 0 ≤ t ≤ 3, which means you can drive for at most 3 hours.
The constraints for the distance are: 0 ≤ d ≤ 55t, which means the distance you drive cannot exceed 55 miles per hour multiplied by the number of hours you drive.
Part B:
No, it is not possible for you to have driven 160 miles. Let's substitute t = 3 into the distance constraint:
d ≤ 55t
d ≤ 55(3)
d ≤ 165
Since 160 is greater than 165, it is not within the range of possible distances you can drive.

The system of inequalities describing the possible numbers of hours and distance is t ≤ 3 and d = t × 55. It is not possible to have driven exactly 160 miles.
Part A:
To describe the possible numbers of hours and distance you may have to drive, we can create a system of inequalities based on the given conditions. Let's denote 't' as the number of hours you drive and 'd' as the distance you cover.
The maximum allowed driving time is 3 hours, so we can write the inequality: t ≤ 3.
Since your maximum speed is 55 miles per hour, the distance 'd' can be calculated using the formula: d = t × 55.
Combining these two inequalities, we have: t ≤ 3 and d = t × 55.
Part B:
To determine if it is possible to have driven 160 miles, we substitute the distance 'd' with 160 in the inequality: d = t × 55. By solving for 't', we can find the allowed range of hours. Plugging in the values, we get: 160 = t × 55. Rearranging the equation, we find t = 160 / 55, which gives t ≈ 2.91.
Therefore, it is not possible to have driven exactly 160 miles, as it falls outside the allowed range of t.

Answer: discrete
Step-by-step explanation:
The graph would be discrete, because you can only order a whole number of pizzas. This means you cannot have 0.4 of a pizza or 3/5 of a pizza. Therefore, p can only be whole numbers, so you cannot draw a line through the points, since prices for non-whole pizzas are not possible.
The graph representing the cost of delivered pizzas depending on the number ordered is discrete because you can only order a whole number of pizzas, therefore the graph will show distinct points for each whole number of pizzas.
The graph representing the cost C, in dollars, for delivered pizza depending on the number p of pizzas ordered would be discrete. This is because you can only order a whole number of pizzas, not a fraction of a pizza. In this case, the number of pizzas p is a discrete variable, as is the cost C. A continuous graph has points that are connected, showing all possible values, while a discrete graph consists of isolated points representing specific values. In our pizza scenario, the graph would indicate specific costs for 1 pizza, 2 pizzas, 3 pizzas, and so on. Hence, the graph will be a series of distinct points, making it a discrete graph.

Answer: 72
Step-by-step explanation:3600 (The number of seconds in an hour)/40 is equal to the number you have to multiply by 800 to get the meters per hour.3600/40=90. 90 x 800 = 72,000. Divide this number by 1000 and you find the answer is 72.Thank me later.I am out.
