Step-by-step explanation:
<u>Linear Modeling</u>
It consist is setting up a linear relationship between two variables, given some experimental data. Only 2 points are needed to set up the equation of a line, but if more than 2 points are used, then the result should use statistical approaches like linear regression to find the best-fit line.
For the question at hand, Marty practices his piano lessons 11 minutes the week #1. It provides the first point (1,11). He practices 25 minutes per day on the third week. It gives us another point (3,25). This is enough to find the equation of a line. The general formula for a line, having two points (m1,w1) (m2,w2) is

Let's plug in our values

Simplifying:


-- least common multiple of 36, 6, 3 = 36
- it is the smallest number divisible <u>by all three. </u>
As x increases by 1 the value of f(x) doubles so we need 2^x
When x = 0 the value of f(x) = 3
The correct answer is f(x) = 3(2^x). [the top option]
Answer:
Sensational Rentals
Step-by-step explanation:
Mr Cool's Rentals-
432 minus 100 = 332
332 * 0.11 = 36.52
36.52 + 36.52 = 73.04 (because she's coming back you need to double it)
73.04 + 99 = 172.04
The cost will be $172.04 if she goes with Mr. Cool's rentals.
Sensational Rentals-
432 minus 150 = 282
282 * 0.15 = 42.3
42.3 + 42.3 = 84.6
84.6 + 75 = 159.6
The cost will be $159.6 if she goes with Sensational Rentals.
Therefore, because 172.04>159.6 Sensational Rentals will have the better deal.
3.25y=13. Isolate y by dividing both sides of the equation by 3.25. So 3.25y/3.25=13/3.25. Your answer is therefore 13/3.25, or 4
