Let's use f(x) for the first one and g(x) for the second.
n is the number of songs downloaded, t is the time in years, and m is the time in months.
f(x) = 125t + 10m
g(x) = 50 + n
For 2, substitute 1 for t and 12 for m.
For 4, solve f(x) = g(x).
For 5, solve g(x) for n=(14*12). Compare it to the value of f(x) for t=1 and 12=m.
7.1 is the value of Ef where cd=df
Answer:
y-9 = 17(x+7)
Step-by-step explanation:
Points given (-8, -8) and (-7, 9)
Point-slope is the general form y-y₁=m(x-x₁)
<u>Finding the value of m using the given points:</u>
- m= (9 - (-8))/(-7 - (-8)
- m = 17/1= 17
<u>Completing the given equation using point 2:</u>
- y - y₁ = m (x - x₁)
- y - 9 = 17(x - (-7))
- y - 9 = 17(x+7)
