What is the value of the expression 2x2 + 3xy – 4y2 when x = 2 and y = - 4?

1 answer:

5 0

Please use " ^ " to denote exponentiation: 2x^2 + 3xy – 4y^2

Now let x=2 and y= -4:

2(2)^2 + 3(2)(-4) - 4(-4)^2 = 8 - 24 -4(16) = -16 - 4(16) = -5(16) = -80 (answer)

b) 4.7 years

Step-by-step explanation:

Attached below is the detailed solution

a) exponential statement in log form for an investment at 15% quarterly

Log ( 2 ) = 4t Log ( 83/80 )

n = 4 , r = 15

b) using change to base to find double time in yr

Double time in yr

t = Log ( 2 ) / 4log ( 83/80 )

= 4.7 years

Genrish500 [490]

N, N+2, and N + 4 are the ages

(N + 4) - (2N) = (N + 2) -24

4 - N = N - 22
