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

What is the equation of the line that passes through (-3,-1) and has a slope of 2/5?
barxatty [35]

Answer:

y = mx + b

-1 = 2/5(-3) + b

-1 = -6/5+b

-1 + 6/5 = -6/5 + 6/5 + b

1/5 = b

y = 2/5x + 1/5

Step-by-step explanation:

  1. write down the slope-intercept form formula
  2. identify your x and y of the point
  3. replace x and y by the point
  4. multiply m and x
  5. do addition to get b
  6. write down the equation by replacing m and b with their values
