Answer:
20
Step-by-step explanation:
From if y=-7 when x=-14 ----> x=2y
that means when y=10, x=20
To divide fractions you swap the numerator & denominator on the second fraction, the multiply the new numerators togeather & multiply the newdenominator together to get the answer. example attached.

Answer:
19.80
Step-by-step explanation:
Given the equation :
y = a (e)^kt
If a = 100, y = 50, and k = -0.035, find t.
50 = 100(e)^(-0.035t)
50/100 = e^(-0.035t)
0.5 = e^-0.035t
Take the In
In(0.5) = - 0.035t
-0.693147 = - 0.035t
-0.693147 / - 0.035 = t
19.8042 = t
Hence, t = 19.80
