Answer:
First relation: It's a function. No order pair need to be changed.
Second relation: It's a function. No order pair need to be changed.
Third relation: It's not a function. The ordered pair (5,8) needs to be changed.
Step-by-step explanation:
A function may not have two y-values assigned to the same x-value.
Each x-element of the first relation has only one y-element associated with it. So we conclude that it's a function.
Each x-element of the second relation has only one y-element associated with it. So we conclude that it's a function.
The points (5,8) and (5,2) shows that there are two y-elements (y=8 and y=2) associated with the value x=5. So we conclude that it's not a function.
Answer:
2:5, 5:2
Step-by-step explanation:
Lets use 30 and 12. 12 divided by 30 is 0.4, which reduced is 2:5, or u can write 0.4. Thats oil to flour
But opposite numbers for flour to oil, bc of common sense.
Hope this helps(would be appreciated if you mark this answer brainliest bc need for lvl up. )
N-6/3=4
<span>n in (-oo:+oo)
n-(6/3) = 4 // - 4
n-(6/3)-4 = 0
n-4-2 = 0
n-6 = 0 // + 6
n = 6
n = 6

Hope this could help : )
Answer:
Let x is the number of the cannon and y is the number of the row boat.Thus the equation will become
8x+5y=110
The correct answer is x = 1/28y^2
