Step-by-step explanation:

Subtract 8 from both sides.

Simplify.

Solve with quadratic formula.
a = 1
b = 4
c = -12
I do not have time to show work for quadratic formula parts.
I am so sorry for this inconvenience.
Answer:
Step-by-step explanation:
2x+5= -25 .........(1)
and -3m-6= 40........(2)
Considering (1): 2x+5= -25
2x = -25 - 5
2x = -30
x = -30/2
x = -15
Considering (2): -3m-6= 40
-3m = 40 + 6
-3m = 46
m = -46/3
Product of x and m = (-15) × (-46/3)
= -5 × -46
= 230
The number of subscribers y to a newspaper after t years is shown by the equation , where 75 is the initial number of subscribers to a newspaper and t is the time period is years.
The above equation can be rewrite as
which is equivalent to the exponential decay function with rate r=0.05=5%
⇒ The number of subscribers to a newspaper decreased by 5% every year.
I think you used the wrong subject.
your answer is B though.
