Solve the simultaneous equations
x² + y² = 34
x-y=2

x=2+y

x^2=4+4y+y^2

so 4+4y+y^2+y^2=34

y^2+2y-30=0

y=(-2+-sqrt(4+120))/1=-1+- sqrt31

Step-by-step explanation: Put each of those y solutions into either equation, and solve for possible x, then test the solutions.

did you get the answer yet?

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
