12×12×12×12×12 is equivalent to 12^5 (a^b means a is to be written down B times all being multiplied.)
Answer:
$192.4
Step-by-step explanation:
First, we'll work out what the customer had to pay before tax.
That's
(USD)
4% of 185 is 7.4,
So the customer paid
(USD)
An equation that would represent the relationship between cost and revenue would be: 7.50t + 15s = 525
Hope this helps!! :)
Kevin linear function is y = 3x + 1 while Jill function is y = 3x - 1
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Using the points (0, 1) and (2, 7), hence for Kevin:
y - 1 = [(7 - 1)/(2 - 0)](x - 0)
y = 3x + 1
Jill’s function has a y-intercept that is 2 less than the y-intercept, hence b = 1 - 2 = -1
Jill function is:
y = 3x - 1
Kevin linear function is y = 3x + 1 while Jill function is y = 3x - 1
