{1,2,3}{1,2,3}?
Answer :C
Step-by-step explanation: For any given function, all first input values (x-values/coordinates) in the relation are considered as the domain values. While the output values (y-values/coordinates) make up the range of the given function.
The mapped relation that has a domain of {1,2,3}, is the mapped relation that has 1, 2, and 3 on the input side on our left.
Therefore, the mapped relation in option C is the answer.
x = 4 and x = 7
x = 0 and x = −7

Answer: To find out how many weeks it will take for Alex to have enough money to buy the smartphone, we need to use the following formula:
weeks=rategoal−saved
where:
goal is the amount of money he needs to buy the smartphone, which is 550$
saved is the amount of money he has already saved, which is 250$
rate is the amount of money he saves per week, which is 30$
Plugging in these values, we get:
weeks=550−250/30
Simplifying, we get:
weeks=300/30
Dividing, we get:
weeks=10
Therefore, it will take Alex 10 weeks to have enough money to buy the smartphone. I hope this helps.
Answer:
Not including the 250$ he already saved, it would take Alex 10 weeks to have to 550$ he needs to buy the smartphone.
Step-by-step explanation:
Subtract 250 from 550 and then divide the difference by 30, since Alex plans on saving 30$ per week. The result is 10, which is your answer.
Hope this helps you!
b) H = A + 2LW/2L + 2W
c) H = A - 2LW/4LW
d) H = A/2L + 2W - 2LW
