There are two steps to this problem. The first step is to make an equation for the cost of each company. The cost of each one involves 2 variables. However, we can ignore the number of days since the question asks for per day.
CostA = 90 + .40(miles)
CostB = 30 + .70(miles)
We want to know when A is a better deal or when A costs less. That is when CostA < CostB. We can then substitute the right sides of our equations into the inequality. This will give:
90 + .40(miles) < 30 + .70(miles) This is where we will now begin to solve for the number of miles.
-30 -30 Subtract 30 from both sides.
60 + .4(miles) < .7(miles) Simplify
-.4(miles) -.4(miles) Subtract .4(miles) from both sides
60 < .3(miles) Simplify
/.3 /.3 Divide both sides by .3
200 < miles Simplify
So for A to cost less the number of miles must be greater than 200.
-35 is the answer hope this helps
(9,30)(18,30)....when u have 2 sets of points and there y value is the same, then u have a horizontal line with a slope of 0
answer : A...it has a slope of 0 because the change in the y values
Answer:
Step-by-step explanation:
20,24,25,27,31,35,38
minimum;20
medium: 27
maximum: 38
lower quartile: 24
upper quartile:35
put numbers in number order
the first number is the minimum, the last number is the maximum. the middle number "split" is the median.
quartiles are the numbers in the middle of the data you just "split"
(so like a quarter)
