Answer: B.) the slope of the function is 20
D.) it cost $20 per hour to repair a laptop
F.) a laptop that requires 4 hours of repair will cost $139
Step-by-step explanation:
The given function is which represents the cost of laptop after t hours.
It is similar to the linear equation , where the slope of equation is m .
Therefore, the slope of the function is 20.
it means it cost $20 per hour to repair a laptop.
To find the x intercept, put c=0 in the equation, we get
To find the y intercept, put t=0 in the equation, we get
y=59
To find the cost after 3 years, put t=3 in the equation, we get
To find the cost after 4 years, put t=4 in the equation, we get
Answer:
The line passing through (-8, 10) and (-1, 4).
Step-by-step explanation:
Two lines are perpendicular if the product of their slopes is -1. The slope of the line in the picture is , so we should find a line with slope of
.
Note that the slope of the line in the last option is .
Question:
Which scenario best matches the linear relationship expressed in the equation y = –14x + 1,700?
1) Kent has $1,700 in his bank account and spends $14 each week.
2) Kent has $1,700 in his bank account and deposits $14 each week.
3) Kent had $1,700 in his bank account and deposited another $14.
4) Kent has $14 in his bank account and spent $1,700.
Answer:
Option 1) Kent has $1,700 in his bank account and spends $14 each week.
Step-by-step explanation:
Let x denote the number of weeks.
Option 1: Kent has $1,700 in his bank account and -14x as the negative sign denotes how much amount he spend each week.
Thus, Option 1 is the correct answer.
Option 2: Kent has $1,700 in his bank account and deposits $14 each week.
Writing it as equation, we have, which is not the expressed linear equation.
Hence, Option 2 is not the correct answer.
Option 3: Kent had $1,700 in his bank account and deposited another $14.
Writing it as equation, we have, which is not the expressed linear equation.
Hence, Option 3 is not the correct answer.
Option 4: Kent has $14 in his bank account and spent $1,700.
Writing it as equation, we have, which is not the expressed linear equation.
Hence, Option 4 is not the correct answer.
Thus, the scenario that matches the linear equation relationship expressed in the equation is Option 1.
The answer is Kent has $1,700 in his bank account and spends $14 each week.
