Sandy has $4,000 invested in stocks and bonds. Last year, she earned 8% interest on the stocks and 6% interest on the bonds. At the end of the year, Sandy received

a check for $270. This was her annual income from the stocks and bonds. Which

system of equations below will determine s, the amount of money Sandy has

invested in stocks, and b, the amount invested in bonds?

F S + b = 4,000

Hs + b = 270

0.08s + 0.06b = 270

4,000

+ b = 270

S

Gs + b = 270

4,000 270 = s

Js + b = 4,000

0.06s + 0.08b = 270

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

p(x)= 8 x³ - 36 x² + 54 x - 27

q(x) = 2 x -3

you can check your mistake and then you can choose the correct option.

dividend =   8 x³ - 36 x² + 54 x - 27

divisor = 2 x -3

if you want to find quotient, proceed as follows

q(x)= 0

2 x - 3=0

x =

now , i have used division method , to find quotient and remainder
