It cannot be be Integers because Integers include negative numbers (which are not counting numbers)
It cannot be real numbers because like integers, it includes negative numbers but also includes decimals which are not counting numbers
It cannot be absolute values because absolute values is the range of how far away a number is from 0 which obviously isn't counting
That leaves natural numbers which are counted in sequence which fits the definition needed
Answer: D. Natural Numbers
Answer:
A) what did the student do wrong, explain why they are incorrect
B) Demonstrate and explain the correct way to answer the question.
Lauren says that two expressions 3x+4(2x+5) and 6x +5x +5 are equivalent. Simplify the expressions to determine whether or not Lauren is correct. Substitute a value for x to see if she is right.
<u>3x+8x+20 = 6x+5x+5</u>
<u>11x+20 = 11x+5</u>
<u>She is wrong</u>
Students answer: She is correct because both equal 11x +5. I substituted x=2 and got 27 for both
<u>She is wrong because 27 will be the answer for ' 11x+5' only. The correct method should be </u>
<u>x=-15 </u>
Step-by-step explanation:
Just look at 1 on the x-axis and go all the way up till you reach the line, then go all the way to the left and see what number that is on the y-axis.
When you do this you find that it's 2 on the y-axis.
So when x = 1, y = 2.
Answer:
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount invested.
P represents the principal or amount invested.
R represents interest rate
T represents the duration of the investment in years.
From the information given,
P = 10000
R = 4%
In the first year, the simple interest would be
I = (10000 × 4 × 1)/100 = $400
The compound interest in the first year is also $400
In the second year, the simple interest would be
I = (10000 × 4 × 1)/100 = $400
For the compound interest in the second year,
P = 10000 + 400 = $10400
I = (10400 × 4 × 1)/100 = $416
The table would be
Simple interest compound interest
1) 400 400
2). 400 416
Total 800 816
