Answer:
3 because when x=2 the lines are at y 1 and 3, but the y 1 isn't shaded, so the answer is 3
Answer:
NOT a solution
Step-by-step explanation:
Substitute the values of x and y and see if the equation is satisfied:
3(1) -7(-1) = 3 +7 = 10 ≠ 4 . . . . . . the given point is not on the line
(1, -1) is not a solution to the equation.
_____
(-1, 1) is a solution
Answer:
94.5 days
Step-by-step explanation:
We are asked to calculate the time.
The formula to calculate the time for half life =
t = t½ × In (Nt/No)/-In2
t½ = half life = 16 days
No = Initial substance = 120mg
Nt = Amount of substances after time t = 2 mg
t = 16 × In (2/120)/-In2
t = 94.510249529736 days
Approximately = 94.5 days
Therefore, the time it would take for the substance to decay from 120mg to 2 mg is 94.5 days.
I think it’s what ever you have left after paying, I’m sorry if this is wrong.
