If given in the following expression, find the value of (x^3 + y^3):(x^3-y^3)
If (x^2+y^2)/(x^2 -y^2)= 17 /8

  76:49  or  49:76

Step-by-step explanation:

The second relation gives an expression for y in terms of x:

Substituting into the expression we want the value of, we can factor out x^3 to get ...

Additional comment

There is nothing in the given requirement that means x and y must have the same sign. If the signs are different, then the value of the expression is less than 1, rather than greater than 1.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
