Answer:

(-1, 3)

Step-by-step explanation:

The given equation is 2x + y = 5.

Test whether (-1, 3) is a solution.  To do this, substitute -1 for x and 3 for y.  Does 2(-1) + 3 = 5?  No, it does not.  So this could be the correct answer choice.

Test whether (6, -7) is a solution.  Is 2(6) - 7 = 5 true?  Yes, it is.  So this is not a correct choice.

Test whether (3, -1) is a solution.  Is 2(3) -1 = 5?  Yes, it is.  So this is not a correct choice.

Summary:  The only answer choice that does NOT satisfy the given equation is the first one:  (-1, 3).

Given the functions, f ( x ) = x - 8 and g ( x ) = x2 x - 1, perform the indicated operation. when applicable, state the domain
kondor19780726 [428]

(fg)(x)= x³ - 7x² - 9x + 8

domain is (-∞,∞)

Given: f(x)= x-8, g(x)= x² +1x - 1

To find (fg)(x) we multiply f(x) and g(x)

(fg)(x) = f(x) * g(x)

(fg)(x)= (x-8) (x²+x-1)

(fg)(x)= x³ + x² - x - 8x² - 8x +8

(fg)(x)= x³  - 7x²  - 9x + 8

we know, domain for all cubic function is set of all real numbers

domain is (-∞,∞)
