Step-by-step explanation:

Use the distance formula:

d² = (x₂ − x₁)² + (y₂ − y₁)²

d² = (-3 − -12)² + (-8 − -11)²

d² = 9² + 3²

d² = 90

d = 3√10

The girls collected 8.5 pounds more than the boys in class 4

<h3>Complete question</h3>

Five classes collected money for a charity of their choice. The amounts of money collected by the boys and girls of each are shown in the chart below.

In Class 4, how much more money did the girls collect than the boys?

<h3>How to determine the difference in amounts?</h3>

From the attached chart, we have the following amount in class 4:

Girls = 12 pounds

Boys = 3.5 pounds

The difference is calculated as:

Difference = Girls - Boys

So, we have:

Difference = 12 pounds - 3.5 pounds

Evaluate

Difference = 8.5 pounds

Hence, the girls collected 8.5 pounds more than the boys in class 4

Explanation:

<u>Part A</u>.

1. You have provided an estimate of 600 minutes per month.

2. The cheapest plan is likely to be Plan 6 (Public Mobile), as it has no per-minute charge.

<u>Part B</u>.

1. Table 2.

See the first attachment for Table 2. For the chosen plan, there is no per-minute charge, so the monthly charge is the same for all numbers of minutes.

2. Rate of Change and Slope (m)

a) Adding a minute adds $0 to the cost

b) The rate of change (m) is 0/1 = 0 (dollars per minute)

3. Initial value (b)

a) The plan costs $24.00 when no minutes are used.

b) The initial value (b) is 24.

4. Equation of the line

a) Filling the found values of m and b into the equation of the line, we have ...

y = mx + b

y = 0x + 24

y = 24 . . . . . . simplified

<u>Part C</u>.

Table 3 can be found in the second attachment.

The b in each case is the value from the <em>Monthly Cost</em> column of Table 1.

The m in each case is the value from the <em>Cost per minute</em> column of Table 1.

The equation is found by copying the values of m and b into y = mx + b.

The number in the last column is found by multiplying the minutes (x) by m, then adding b. <em>For example</em>, your cost for Plan 5 (BELL) is ...

y = 0.10x + 10

y = (0.10)(600) +10 = 60 +10 = 70
