Answer:
y = 2x + 1
Step-by-step explanation:
y (the sandwich) is TWICE the price of soup (2x) plus one (+1)
good luck
Answer: 180 feet
Equipment depth:
5 x 17 = 85
5 x 19 =95
95 + 85 = 180
Miner depth:
17 feet per second x 19 seconds = 323 feet
Using a linear function, it is found that he drove the truck for 240 miles.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Researching the problem on the internet, there was a base fee of $18.99, which is the y-intercept, and there was an additional charge of 75 cents for each mile driven, which is the slope, hence the cost function for m miles driven is given by:
C(m) = 18.99 + 0.75m.
He paid $199, hence the number of miles he drove is found as follows:
C(m) = 18.99 + 0.75m.
199 = 18.99 + 0.75m
m = (199 - 18.99)/0.75
m = 240 miles.
