Answer:
$36.00
Step-by-step explanation:
The formula for simple interest is I = P x r x t where P is the principal amount, $600.00, r is the interest rate, 2% per year, or in decimal form, 2/100=0.02, and t is the time involved, 3....year(s) time periods. So t is 3....year time periods. To find the simple interest, we multiply 600 × 0.02 × 3 to get that the interest is $36.00 . Usually now, the interest is added onto the principal to figure some new amount after 3 year(s), or 600.00 + 36.00 = 636.00.
Answer:
First, we need to determine the slope of the line going through the two points. The slope can be found by using the formula:
m
=
y

y

Where
m
is the slope and (
x

,
y

) and (
x

,
y

) are the two points on the line.
Substituting the values from the points in the problem gives:

Now, we can use the point-slope formula to find an equation going through the two points. The point-slope formula states:
(

Where
m
is the slope and

is a point the line passes through.
Substituting the slope we calculated and the values from the first point gives:
(

We can also substitute the slope we calculated and the values from the second point giving:

We can also solve the first equation for

Where

Answer:
B
Step-by-step explanation:
The association is positive linear so that means everything is increasing as the line goes up.

Answer:
-1.5
negative and negative
Step-by-step explanation:
the number line shows 3 * -1.5 = -4.5
the number line shows three groups of a negative number, which results in a negative.
