Answer:
$14,700
Step-by-step explanation:
interest rate is $900 per year (12000×.075)
$900 × 3 years = $2,700
add $2,700 to $12,000 (amount borrowed)
total is $14,700
Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect
anyway the easier way is to factor but anyway
0=(x-4)(x+2)
anyway
solution is x=4 and -2
A and D are answers (they are same)
Answer:
The numbers are;
x = 100/3, y = 100/3, z = 100/3
Step-by-step explanation:
Given the data in the question;
so let the numbers be; x , y and z
so
x + y + z = 100
now
G(x,y,z) = x + y + z - 100
F(x,y,z) = xyz
Fx = yz, Gx = 1
Fy = xz, Gy = 1
Fz = xy, Gz = 1
Fx = λ × Gx
yz = λ
Similarly, xz = lambda
And xy = lambda
From above clearly, x = y = z
x + y + z = 100
so
3x = 100
x = 100/3
since, x = y = z therefore, each number is equal to 100/3
x = 100/3, y = 100/3, z = 100/3
