  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

3x + 2y = -16

-3x - 8y = 46

<u>Step 2: Solve for </u><em><u>y</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                    -6y = 30
  2. Divide -6 on both sides:                 y = -5

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Define equation:                    3x + 2y = -16
  2. Substitute in <em>y</em>:                       3x + 2(-5) = -16
  3. Multiply:                                  3x - 10 = -16
  4. Add 10 on both sides:            3x = -6
  5. Divide 3 on both sides:         x = -2

Step-by-step explanation:

We can see from the graph that

A it is a polynomial

C that is has 3 real root ( where it crosses the x axis)

D that is contains the point (0,-20)  

What is not true is that it is periodic.  That would mean it repeats after a certain time.

Let's assume that the entire are in the distribution curve is 1

Given

Time taken from 0s to 30s = 30s - 0s = 30s

To find height of the distribution?

Let H = the height of the distribution

Based on the above assumption;.

H * 30 = 1 --- make H the subject of formula

H = 1/30

H = 0.0333

Hence, the calculated height of the distribution is 0.0333
