Nostrana [21]

Step-by-step explanation:

\frac{y_2-y_1}{x_2-x_1}=\frac{15-(-13)}{28-(-28)}\\=\frac{28}{2(28)}\\\therefore\ m=\frac{1}{2}\\\frac{y-y_1}{xl-x_1}=m]\\\frac{y+13}{x+28}=\frac{1}{2}\\2y+26=x+28\\2y=x+2\\ y=\frac{1}{2}x+1

In order to find y for point C on AB, substitute point C in line equation if AB.

y=\frac{1}{2}(-24)+1\\\therefore y=-12+1=11\\\therefore C(-24, -11)

The missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4 and the missing expression should be for Step 6 is 56 - 4.1

<h3>Part A: Explain what the missing expression should be for Step 3</h3>

To do this, we make use of the expression in step 2

The expression in step 2 is

[(5^2 + 3)/0.5] - 16.4 ÷ 4

The next step at this stage is to evaluate the expression 5^2

So, we have:

[(25 + 3)/0.5] - 16.4 ÷ 4

Hence, the missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4

<h3>Part B: Explain what the missing expression should be for Step 6.</h3>

To do this, we make use of the expression in step 5

The expression in step 5 is

56 - 16.4 ÷ 4

The next step at this stage is to evaluate the expression 16.4 ÷ 4

So, we have:

56 - 4.1

Hence, the missing expression should be for Step 6 is 56 - 4.1
