The relation you have shown is not a function.
In order to be a function, a relation's domain must be continuous in that no x-value is not repeated in any of the points. Since the first two points of the relation are (5,1) and (5,3), you can see that they have the same x-value, meaning that this is not a function.
One quick way you could test this is to quickly sketch a graph and use the vertical line test to see if the relation in question is a function. If it cross the vertical line once in all places, it is a function - if it crosses the vertical line more than once in any place, it is not a function.
3 ( 2t + 5 ) = 5 t + 25
3 * 2 t + 3 * 5 = 5 t + 25
6 t + 15 = 5 t + 25
6t - 5t = 25 - 15
t = 10
Hope this helps!
Answer:
4a^2 (8a+3)
Step-by-step explanation: it’s right
14=6+2x
