Answer:
The integers are (x, y) = (40, 8).
Step-by-step explanation:
x = 5y
xy = 320
Substitute the first equation into the second equation.
(5y)(y) = 320
5y^2 = 320
y^2 = 64
y = 8 (y must be positive)
The integers are (x, y) = (40, 8).
This is a cubic equation so it will have a total of three roots.
there is only one change of sign so the equation will have one positive real root.
The other 2 roots will be negative and might be real or complex
I think this might be the answer you're looking for m^3n/p^2
Answer:
A. 1 /14
Step-by-step explanation:
3 1/2 / 1/2 = 1 /14
I=PRT
I=interest
P=principal
R=rate in decimal
T=time in years
we want to find how much he earns when he invests 1250, on 5%, and how much per month, or 1/12 years
P=1250
R=0.05
T=1/12
I=1250(0.05)*(1/12)
I=62.5/12
I=5.2083333
round to nearest cent
I=$5.21
about $5.21 per month
