Answer:

  • y = 260x + 700
  • $5900

Step-by-step explanation:

<u>We can describe it as a linear function with points of:</u>

  • (5, 2000) and (15, 4600)

<u>Slope intercept formula:</u>

  • y = mx +b

<u>Finding the slope using the two given points:</u>

  • m = (4600-2000)/(15-5) = 2600/10 = 260

<u>Finding b:</u>

  • 2000 = 5*260 + b
  • b = 2000 - 1300 = 700

<u>Formula obtained:</u>

  • y = 260x + 700

<u>For x = 20, value of y is:</u>

  • y = 260*20 + 700 = 5200+700 = $5900

Answer:

Statements                       Reasons

1. 2x + 11 = 15                    1. Given

2. 2x = 4                            2. Subtraction Property of Equality

3. X = 2                              3. Division Property of Equality

Step-by-step explanation:

An equation can be solved and its solution proven using algebraic theorems and properties. To create a proof, form two columns. Label one side Statements and the other Reasons.

Begin your proof listing the any information given to you. List as the reason - Given.

Then list the next step which here would be to subtract by 11 on both side. The reason is Subtraction Property of Equality. Subtraction is the inverse of addition. Inverse axiom is another acceptable reason.

Then divide both sides by 2. The reason is Division Property of Equality or Inverse axiom once again. See the proof below.

Statements                       Reasons

1. 2x + 11 = 15                    1. Given

2. 2x = 4                            2. Subtraction Property of Equality

3. X = 2                              3. Division Property of Equality
