<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:
D = 36 - 4 * 9 *(-2) = 104

x1= -{-6} - 2 that shet 26/6 x2=-{6}+ 2 that shet 26/6
Answer:
(-1,4)
Step-by-step explanation:
Using elimination, add the two equations to get rid of the y variable.
17x = 43 - 15y
+8x = -68 + 15y
=25x = -25
<u>x = -1</u>
Now plug in -1 for x in any of the equations.
17(-1) = 43 - 15y
-17 = 43 - 15y
-60 = -15y
<u>y = 4</u>
Answer:
Step-by-step explanation:
The weight of an object is the magnitude of the force of gravity acting on the object. It is equal to the product between mass of the object (m) and acceleration of gravity (g):
In this problem, we have 100 sharks; the weight of each shark is
When we have n objects, the total weight of the n object is n times the weight of each object:
Therefore, since in this case
n = 100
The total weight of the 100 sharks is:
