Answer:
3 times 9
Step-by-step explanation:
3^3 = 3*3*3 = 27 = 3*9
(-3,-7) because the two lines have different slopes an the point that they intersect is the point i listed above
Answer:
She needs to invest $13,636.36 right now
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:
In 15 years, so
She wants to have $30,000, so
8% interest, so
We have to find P.
Replacing:
She needs to invest $13,636.36 right now
Answer:
Step-by-step explanation:
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1)
so it would be
11-(-1)/12--4)
which would be
12/16
to simplify that it is 3/4
