Answer:
A... 12
Step-by-step explanation:
Answer:
Step-by-step explanation:
11) $175(1 - 0.30)(1 + 0.06) = $129.85
12) slope is 2, so basic equation is
y = 2x + b
plug in your desired point
-5 = 2(-4) + b
b = 3
y = 2x + 3
Answer:
x = -1
Step-by-step explanation:
2x + 3 = -3x -2
2x = -3x -5
5x = -5
x= -1
Using the given linear function, it is found that the slope is of 73, which means that for each traffic ticket, the cost of car insurance increases by $73.
<h3>What is a linear function?</h3>
A linear function is modeled by:

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.
In this problem:
- x represents the number of traffic tickets.
- y represents the cost of car insurance.
The function is:

Hence the slope is of 73, which means that for each traffic ticket, the cost of car insurance increases by $73.
