Look at the first image below for the known points...
Since this is a rectangle the missing point must align underneath the point (4, -3). This means that the missing point will need to have an x value of 4
The missing point must also align to the right to the point (-2, -5). This means that the missing point will need to have a y value of -5
This makes the missing point...
(4, -5)
Hope this helped!

Answer:
It will take 7 years ( approx )
Step-by-step explanation:
Given equation that shows the amount of the substance after t years,
Where,
= Initial amount of the substance,
If the half life of the substance is 19 years,
Then if t = 19, amount of the substance = ,
i.e.
Taking ln both sides,
Now, if the substance to decay to 78% of its original amount,
Then
Again taking ln both sides,
Hence, approximately the substance would be 78% of its initial value after 7 years.
Answer:
Step-by-step explanation:
Let x be the number.
6 times the number = 6*x = 6x
Sum of 6 times of a number and twelve = 6x + 12
Three-fourths of the sum of 6 times of a number and twelve =
