Answer:
can u explain this a little bit more i think ik the answer but im not sure #3 is well i think it is 120#4 is 164.85 #5 is 40 yea hope this helps :)
Step-by-step explanation:
X + 3y = 12...when x = 1
1 + 3y = 12
3y = 12 - 1
3y = 11
y = 11/3
x + 3y = 12....when x = 2
2 + 3y = 12
3y = 12 - 2
3y = 10
y = 10/3
x + 3y = 12...when x = 3
3 + 3y = 12
3y = 12 - 3
3y = 9
y = 3
table :
x y
1 11/3
2 10/3
3 3
Answer:
Well, you didn't give a picture of the available mapping diagrams, so I can't tell you that. However, I CAN tell you that the relation is not a function.
Step-by-step explanation:
A function occurs when each input only has one output. For example if the input is 5, it can only give 1 y-value out. It cannot give 2,3,4...etc values. This relation is not a function because -5 maps to both -4 and 3. That's one input to two outputs, which breaks the rules of a function.
Answer:
5
Step-by-step explanation:
5 × 5 × 5= 125 so 5 is the cube root
The x’s must all be different. So if any x’s repeat it is not a function
