Answer: Domain: (1,+inf) range (1800,inf)
Step-by-step explanation:
assuming that he cant sell negative cars or 0 cars this is the domain and range
The value of ac is -1
Step-by-step explanation:
Let us revise some rules
- The slope-intercept form of the linear equation is y = m x + b, where m is the slope of the line and b is the y-intercept
- The product of the slopes of the perpendicular lines is -1
∵ The equation of the first line is y = a x + b
- The equation of the line in the slope-intercept form
∴ m = a
∴ The slope of the line = a
∵ The equation of the second line is y = c x + d
- The equation of the line in the slope-intercept form
∴ m = c
∴ The slope of the line = c
∵ The two lines are perpendicular
∵ The product of the slopes of the perpendicular lines is -1
- Multiply the two slopes and equate the product by -1
∴ (a)(c) = -1
The value of ac is -1

Answer:
Option D is correct answer.
Step-by-step explanation:
The correct answer is option D- "The date that the check is written is usually a few days before it is cashed. We record when it was cashed and you record when its written".
It takes up to 3-4 business day to cash a check. So, Kevin might have entered the date when he wrote the check but as the check was cashed a few days after, the bank would have entered that date. So, it caused the confusion.
Options A, Band C are not correct as if it would have been option A, Kevin would have seen it before calling the bank. It cannot be option B either as banks don't do such silly mistakes. Option C cannot be true either as this type of error has nil chances to occur.
That means to multiply right? it's 10,800
