Answer:
She needs to put the meal in the oven on or before 6:55pm.
Step-by-step explanation:
It is given that Jasmine wants to eat at 8:00pm.
The time she needs to cook her meal = 65 mins.
To find the time she needs to put the meal in the oven, we have to subtract 65 mins from 8:00pm
65 mins = 1 hour and 5 mins.
So, 1 hour before 8:00pm is 7:00pm.
5 mins before 7:00pm is 6:55pm.
Hence, she needs to put the meal in the oven on or before 6:55pm so that she can't miss 800pm to eat.
Which of the sets of ordered pairs represents a function? A={(-4, 5), (1, -1), (2, -2), (2, 3)} B = {(2, 2), (3, -2). (9. 3). (9
EastWind [94]
Answer: Neither A or B
Step-by-step explanation: In order for a relation to be a function, a relation can not have the x-values repeat. Y-values can repeat an infinite amount of times but x-values can only repeat 1 time in a given relation. In relation A, you have (2,-2), and (2,3) and relation B, you have (9,3), and (9,-3). You can also graph both of these relations and do a vertical line test with your pencil and see that it would cross more than once.
Hope this helps.
