In the question, you were told:
x = # of lines in the ad
y = cost of ad, in dollars
So you're now told 12 lines costs $88.
How do you write that as an ordered pair? Do we write ordered pairs as (x,y) or (y,x)?
Answer:
Step-by-step explanation:
- x² + 20² = 25²
- x² + 400 = 625
- x² = 225
- x = √225
- x = 15
Answer:
A=25000 is the future value. P the value that we need to invest. r= 0.04 represent the interest rate in fraction. n = 12 represent the number of times that the rate is compounded in a year. t = 5 years.
If we solve for the value of P we got:

And replacing we got:

And rounded to the nesrest penny we need to invest $20475.08 in order to have after 5 years $25000
Step-by-step explanation:
For this case we can use the future value with compound interest given by:

Where:
A=25000 is the future value. P the value that we need to invest. r= 0.04 represent the interest rate in fraction. n = 12 represent the number of times that the rate is compounded in a year. t = 5 years.
If we solve for the value of P we got:

And replacing we got:

And rounded to the nesrest penny we need to invest $20475.08 in order to have after 5 years $25000
Answer:
See below
Step-by-step explanation:
c = (a^2 + 3b) / 4 multiply both sides by 4
4c = a^2 + 3b subtract a^2 from both sides
4c - a^2 = 3b now divide both sides by 3
(4c-a^2) / 3 = b
The probably of this happening is 1/169
