Answer:
Yes because the 1st and 3rd one are functions
Step-by-step explanation:
Answer: (3,4)
Each input can only have one output for a function
The other pairs give a different output for the input so that would make it a relation not a function.
Answer:
t=0 and t=5
Step-by-step explanation:
5t = t^2
Subtract 5t from each side
5t-5t = t^2 -5t
0= t^2 -5t
Factor out a t
0= t(t-5)
Using the zero product property
t=0 and t-5 =0
t=0 and t-5+5=0+5
t=0 and t=5
(a,7) lies on the equation of 5x-y=8, that means we solve for x when y=7.
5x-(7)=8
5x=8+7=15
x=3
=>
a=3
