Answer:
Only the given table represents a function. Option 1 is correct.
Step-by-step explanation:
A relation is called a function, if there exist a unique value of y for each value of x. It means for each input there exist a unique output.
A function is always a relation but all relations are not function.
In the given table for each value of x, we have unique value of y, therefore the given table represents a function.
In second relation, at x=-2, the values of y are y=10 and y=-7. For single x, there are more than one value of y, therefore the second relation is not a function.
In third relation, at x=6, the values of y are y=-2 and y=1. For single x, there are more than one value of y, therefore the third relation is not a function.
Step-by-step explanation:
X+100=180(linear pair)
X=180-100
X=80
30+y+x=180(sum of angle of triangle)
Y=180-110
Y=70
<em>Answer:</em>
<em>24</em>
<em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>175% ............. 42</em>
<em>100% ..................x </em>
<em>x = 100*42/175 = 4200/175 = 24</em>
<em>Good luck !</em>
Answer:
c = 28
Step-by-step explanation:
Solve for c by simplifying both sides of the equation, then isolating the variable.
