2t−5=−10 what is t I really need help
2 answers:
t = -2.5 or 
Here's how we find that out:
2t -5 = -10..........................We need to get the variable, t, by itself
2t = -5................................Add 5 to both sides
t = -2.5...............................Divide both sides by 2
So, your answer is
0r -2.5
I hope this helped! Have a great day! :))

Answer:
Step-by-step explanation:
We will use 2 coordinates from the table along with the standard form for an exponential function to write the equation that models that data. The standard form for an exponential function is
where x and y are coordinates from the table, a is the initial value, and b is the growth/decay rate. I will use the first 2 coordinates from the table: (0, 3) and (1, 1.5)
Solving first for a:
. Sine anything in the world raised to a power of 0 is 1, we can determine that
a = 3. Using that value along with the x and y from the second coordinate I chose, I can then solve for b:
. Since b to the first is just b:
1.5 = 3b so
b = .5
Filling in our model:
Since the value for b is greater than 0 but less than 1 (in other words a fraction smaller than 1), this table represents a decay function.
