Answer:

D. (1, -2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

5x - 2y = 9

3x + 4y = -5

<u>Step 2: Rewrite systems</u>

10x - 4y = 18

3x + 4y = -5

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

  1. Add to equations together:                    13x = 13
  2. Divide 13 on both sides:                          x = 1

<u>Step 4: Solve for </u><em><u>y</u></em>

  1. Define:                              3x + 4y = -5
  2. Substitute in <em>x</em>:                 3(1) + 4y = -5
  3. Multiply:                            3 + 4y = -5
  4. Isolate <em>y </em>term:                  4y = -8
  5. Isolate <em>y</em>:                           y = -2

And we have our final answer!

faltersainse [42]

Answer with explanation:

It is given that, there is positive correlation between drinking coconut milk and eating potato chips.

→Correlation coefficient is denoted by r.

→The value of r lies between , -1 and 1 which is represented as , -1 ≤r≤1.

→Correlation that is relation between two variables is said to be strongly positive, if r is equal to 1, and it is said to be strongly weak, if it is equal to -1 , and said to have no association if r=0.

→ The meaning of positive correlation is that value of r, is greater than >0.8 but less than 1.

The two variables which are positively correlated ,can have following relationship.

1. With increase in one other increases.

2.With decrease in one other decreases.

3. Slope will be a linear that is a straight line not passing through origin.
