<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:


Answer
y = 6x
Explanation
To write a recursive or explict rue for this sequence, we need to firstly examine the given sequence.
If we let money spent = y and number of weeks = x
when x = 1, y = 6
when x = 2, y = 12
when x = 3, y = 18
when x = 4, y = 24
We can easily see that as x increases by units of 1, the y increases by corresponding units of 6.
A rule that will work for this is that
y = 6x
so that, when x = 1, y = 6(1) = 6 (as it is on that graph)
when x = 2, y = 6(2) = 12 (as it is on that graph again)
And so on.

Answer:
b= 4 in.
Step-by-step explanation:
Ok. So the area of a triangle is base * height divided by 2.
So, the base is b and the height is 3b.
b*3b= 3b^2.
Now, divide that by 2.
(3b^2)/2.
Now, we know what the area is already- 24 in.^2. So, let's set the area expression that I found earlier equal to this area, since they're the same.
(3b^2)/2 = 24
3b^2 = 48
b^2 = 16
Ok. Let's stop here. Now, we square root both sides to obtain b, but we are presented with a problem here. B can equal both 4 and -4 right? Since -4*-4=16 and 4*4=16. However, it is impossible for a 2d shape to have negative measurements. So, the answer is 4.
