To make t the subject is basically isolating t
S = at + bt
We see on the right side that t is common, so we factor it out.
S = t(a + b)
Divide by (a+b) to isolate t

a + b and a + b cancels out
We are left with the answer:
t =
Answer:
B) y=0
Step-by-step explanation:
The exponential function shown has a horizontal asymptote at the line y=0, which means that y will approach 0 as the value of x decreases. Therefore, B is correct.
Answer: m∡B°=38,2°.
Step-by-step explanation:
a=3, b=5, c=7 ∡B°=?

m∡B°=arccos
m∡B°≈38,2°.
Good luck!
