Answer: No
Explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.
In the relation shown here, notice that
the x-coordinate 2 appears twice.
In one case, 2 corresponds to -4 and in
the other case, 2 corresponds to -4.
Since the x-coordinate 2 corresponds to more than one
y-coordinate, no, this relation is not a function.
Answer:
0.02(750)+0.03(x−750)=37.5
Step-by-step explanation:
Given data
Melissa earns a 2% commission on the first $750 of sales
= 0.02(750)
She earns a 3% commission on the amount of her sales that are greater than $750 each week
let the amount of her sales be x
= 0.03(750-x)
Melissa earned $37.50 in commissions last week.
= $37.5
Her total earnings is $37.5
37.5= 0.02(750)+ 0.03(x-750)
37.5= 15+0.03x- 22.5
37.5-15+22.5= 0.03x
45= 0.03x
x= 45/0.03
x= 1500

Step-by-step explanation:
Let the width be W.
14w=(8*10)
14w=80
The width of the frame needs to be at least 5.7 inches.
Answer:
4
Step-by-step explanation:
Amount spent on coffee = 70 - 39.56 = 30.44
One pound costs 7.61, how many will cost 30.44
7.61 : 1 = 30.44 : X
7.61 = 30.44/X
X = 30.44/7.61
X = 4
Answer:
They're not parallel, because 4x and 12x are not the same slope
