Step-by-step explanation:
1st
8x-59 + 2x-11 = 180
10x -70 = 180
10x = 180 + 70
10x = 250
x = 25
2nd
8x - 59 = 15y + 6
8(25) -59 = 15y + 6
200 -59 = 15y + 6
141 = 15y + 6
15y + 6 = 141
15y = 141 - 6
15y = 135
y = 135/15
y = 9
A Relation is said to be a Function if an element of Domain of the Function has one and only one image in the Co-domain of the Function.
⇒ A is not a Function, Because Element 4 has Three images
⇒ B is a Function, Because Each Element has a Unique Image
⇒ C is not a Function, Because Element 7 has Two images
⇒ D is a Function, Because Each Element has a Unique Image
⇒ E is a Function, Because Each Element has a Unique Image
So, The Relations which are Functions are : B - D - E
Answer: y=5x+100
Step-by-step explanation:
the y intercept is the 100$ invested into the account, and the rate of change is 5
-3, -1, 1, 3, 5 would be five of them.
-5 since A is at 5 you would take negative A and get -5
