Given 2x+y=6 perform the necessary operations to put equation into the proper general form.Explain in complete sentences how you
VashaNatasha [74]

Answer:

2x + y -6 = 0

Step-by-step explanation:

The general form is Ax+By + C= 0. It requires that A and B be greater than 1 (not fractions or decimals) and A is positive. This equation is 2x + y = 6 is almost already in the form.  Subtract C to both sides to make it general form. 2x + y - 6 =0. The coefficients of the x and y are greater than 1 and 2 is positive. This meets the requirements.

Help Please, anyone good at domain values of composite functions.
Delicious77 [7]

Answer:

second choice

Step-by-step explanation:

(f \circ g)(x) =

= f(g(x))

= f(-7x + 7)

= \sqrt{-7x + 7 + 3}

= \sqrt{-7x + 10}

Let x = 5:

(f \circ g)(5) = \sqrt{-7(5) + 10}

(f \circ g)(5) = \sqrt{-35 + 10}

(f \circ g)(5) = \sqrt{-25}

Since using x = 5 gives the square root of a negative number, 5 is not in the domain of the composition of the functions.

Answer: second choice
