Answer:
2 hours
Step-by-step explanation:
Slope represents the hourly rate.
Constant represents initial price.
![y = 30 + 6x \\ y = 36 + 3x \\ 30 + 6x = 36 + 3x \\ 3x = 6 \\ x = 2](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%206x%20%5C%5C%20y%20%3D%2036%20%2B%203x%20%5C%5C%2030%20%2B%206x%20%3D%2036%20%2B%203x%20%5C%5C%203x%20%3D%206%20%5C%5C%20x%20%3D%202)
Answer: $169,500
Step-by-step explanation:
The mean simply means the average price of a set of a numbers that are given. For one t calculate the mean, one has to add the numbers that are given and then divide them by the amount of numbers.
I'm the case above, the numbers given are $165,000, $188,000, $175,000, and $150,000.
Mean = ($165,000 ,+ $188,000 +$175,000 + $150,000) ÷ 4
= $678,000/4
= $169,500
Answer: B 386
Step-by-step explanation:
(7*15)*2 + (7*4)*2 + (15*4)*2
= 210+120+56
= 386
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
The 2 and + are out since they don't have variables(and the + is just a +).
So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.
