Answer:
the answer is true
Step-by-step explanation:
the x values don't repeat themselves so therefore it is a function
Step-by-step explanation:
2t² + 3
2 x 9 + 3
18 + 3
21 is instanous rate
I think the answer is this
2x-4x+1=0
Combine like terms
-2x+1=0
Subtract 1 both sides
-2x=-1
Divide by -2 both sides
x=-1/2
21/2%=
21/0.02=
1,050
21 is 2% of 1,050
Check:
1,050*2%=
1,050*0.02=
21
