Answer:

The point (3, 3) is not a solution of the first equation, therefore is not a solution of the given system of equations.

Step-by-step explanation:

$y=3x+6\ and\ y=-2x+9$

$(3,\ 3)\to\text{put x = 3 and y = 3 to the equations of the functions}\\\text{and check the equality.}\\\\y=3x+6\\\\3=3(3)+6\\3=9+6\\3=15\qquad\text{FALSE!}$

The volume would be 4.19 because you would do V=(4/3)(pi)(1^3) :) thats how you get your answer :)

100 points if you can answer this

horrorfan [7]

Answer:

x = 124°

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 , then

sum = 180° × 3 = 540°

sum the given angles and equate to 540°

90° + 122° + 105° + 99° x = 540° , that is

416° + x = 540° ( subtract 416° from both sides )

x = 124°

Which expression is a linear factor of x6 +x-66?

Naddik [55]

Answer:

Option D.

Step-by-step explanation:

The given expression is

$x^6+x-66$

It is a polynomial.

(x-c) is a linear factor of polynomial p(x) if p(c)=0.

Substitute x=-1 in the given expression.

$(1)^6+(1)-66=-64\neq 0$

It means (x+1) is not a linear factor of given expression.

Substitute x=-2 in the given expression.

$(-2)^6+(-2)-66=-4\neq 0$

It means (x+2) is not a linear factor of given expression.

Substitute x=-4 in the given expression.

$(-4)^6+(-4)-66=4026\neq 0$

It means (x+4) is not a linear factor of given expression.

None of the given options are a linear factor of given expression.

Therefore, the correct option is D.
