Answer:

  A. no solution

  B. unique solution: (x, y) = (0, 0)

Step-by-step explanation:

For these problems, you can subtract the second equation from the first to get something of the form ...

  0 = (expression)

The solution of that will tell you the answer.

__

A. (2x +3y) -(2x +3y) = (4) -(9)

  0 = -5 . . . . . . . . no values of x or y will make this true: NO SOLUTION

__

B. (y) -(y) = (6x) -(x)

  0 = 5x

  0 = x . . . . . . divide by the coefficient of x.

  y = x = 0

The unique solution is (x, y) = (0, 0).

The number of cubic feet of water in a curved container can be approximated by v = 0.95h2.9. use a calculator to find the amount
Sati [7]
The first thing we must do for this case is to rewrite the expression of the volume correctly.
 We have then:
 v = 0.95 * h ^ 2.9
 Substituting the value of h we have:
 v = 0.95 * (7.5) ^ 2.9
 v = 327.6432831
 round to the nearest tenth:
 v = 327.6 feet ^ 3
 Answer:
 
the amount of water in the container when h = 7.5 feet is:
 
v = 327.6 feet ^ 3

stiv31 [10]

Answer:

Step-by-step explanation:

I think you meant x^(3/2).  This breaks down in at least two ways:

[x^3]^(1/2), or √(x^3)m or √x³), or

[x^(1/2)]^3 = (√x)^3
