X+4y= -9 y=2x+6 is (2,3) a solution of the system ?

no

Step-by-step explanation:

easy way to find out...just do some subbing...but remember, for it to be a solution to this system, it has to satisfy both equations.

(2,3)...x = 2 and y = 3

-x + 4y = -9

-2 + 4(3) = -9

-2 + 12 = -9

10 = -9 (nope)no need to check the other one because it does not satisfy this one.

It is NOT a solution

B)  $2904.59

Step-by-step explanation:

Compounded continuously means that the principal amount is constantly earning interest and the interest keeps earning on the interest earned.

The formula to apply is

A= Pe^rt

where A is the amount, P is the principal, r is rate of interest, t is time in years and e is the mathematical constant.

Taking

e=2.7183, P=$2500,  r=3% and t=5 years

Hope this helps (:
