Answer:
y = 
x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = , then
y = x + c ← is the partial equation
To find c substitute (- 4, - 7 ) into the partial equation
- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1
y = x - 1 ← equation of line

Step-by-step explanation:
We let f(0) = 235
After 1 month,
f(1) = 235*(0.7) + 50
After 2 months,
f(2) = 235*0.7*0.7+ 50*2
And so on..
Therefore, we can represent the number of MP3 players in the store after n months with the function:
f(n) = 235 (0.7)^n + 50n
I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:
So, we know that 5/2 gallons cost 60 dollars, which means
To find the cost of a single gallon, we have to solve the equation for g:
Answer:
Your answer is 46 minutes.
Step-by-step explanation: By doing the median of the numbers you order the pairs from least to greatest. 38, 45, 47, 52. You find the middle number if its an even number of pairs you pick the two middle most numbers and add them together.
45 + 47= 92
Then you divide the sum by the number of pairs. Which we have 2 pairs.
92/2 = 46 hence your answer will be 46 minutes.
