Answer:
<h2>No, because the graph of the line connecting the ordered pairs does not pass through the origin.</h2>Step-by-step explanation:
When two linear variables are directly proportional, the realtion has the form
Where is the contant ratio of change between variables.
One important characteristic of the direct proportion is that its graph is a straight line which passes through the origin.
However, you can notice in the given image that the line formed by those points won't intercept the origin of the coordinate system.
Therefore, the right answer is the second choice.
Answer:
Step-by-step explanation:
Let's FOIL out both sides and then see where we are after that:
Let's combine like terms now and get everything on one side of the equals sign and set the polynomial equal to 0 to solve for x:
0 = 8x - 4 and we can factor out a 4 to give us:
0 = 4(2x - 1)
Either 4 = 0 or 2x - 1 = 0. Well it's obvious that 4 does not equal 0, so 2x-1 must equal 0. Then
2x = 1 so
x = 1/2 or choice A on the left.
Answer:
To calculate annual compound interest, multiply the original amount of your investment or loan, or principal, by the annual interest rate. Add that amount to the principal, then multiply by the interest rate again to get the second year's compounding interest
Step-by-step explanation:
A = P (1+ r/n) ^nt
A = final amount is found if you input 12 months at r
P = initial principal balance = $100 if every month
r = interest rate then interest rate will be 12 month
n = number of times interest applied per time period = 1
t = number of time periods elapsed t = eg 10
