Answer:

  $12600

Step-by-step explanation:

If x represents the total investment, then the total interest is ...

  (x/3)(0.02) +(x/3)(0.07) +(x/3)(0.08) = 714

  x(.17) = 2142 . . . . multiply by 3; collect terms

  x = 2142/0.17 = 12600

The total investment was $12,600.

For y = 4x + 2x2 – x3, show how to find the value for y, when x = 2. Show your work
shusha [124]
To find the value of y in the given equation, substitute the given value of x to the equation.
   
                               y = 4x + 2x² -x³

Substitute 2 for all x's.
  
                               y = 4(2) + 2(2²) - 2³ = 8

Therefore, the value of y is 8.

Round to the nearest hundredth 5/8
Solnce55 [7]
Eighths and their multiples are common fractions which I recommend memorizing, but to actually solve this, you use the literal meaning of a fraction and divide 5 by 8. See the long-division below (it was surprisingly difficult to type, so I hope it helps!).

To round 0.625 to the nearest hundredth, we go to the second decimal place, which is 5, so we round up to 0.63.
