Answer:
The answer is 3
Step-by-step explanation:
Answer:
y = -5/7x - 55/7
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define
Slope <em>m</em> = -5/7
Random point (-4, -5)
y = -5/7x + b
Step 2: Find y-intercept <em>b</em>
-5 = -5/7(-4) + b
-5 = 20/7 + b
b = -55/7
Step 3: Write linear equation
y = -5/7x - 55/7
Answer:
The line between the points C and E is parallel to the line between the points F and B
The line between the points A and E is parallel to the line between the points B and D
The line between the points A and C is parallel to the line between the points F and D

Answer: $44.10</h3>
====================================================
Work Shown:
5% = 5/100 = 0.05
5% of 42 = 0.05*42 = 2.10
tax = $2.10
total cost including tax = $42 + $2.10 = $44.10
----------
An alternative is to multiply 42 by 1.05 to get
1.05*42 = 44.10
We get the same answer. The 1.05 refers to 1 + 0.05 where the "1" is 100% and the 0.05 is 5%, so the two combine to 105%, meaning the total cost is 105% of the cost before tax is considered.
