Answer:

$\displaystyle x = 8$

Step-by-step explanation:

Anything set to equal x is considered an undefined rate of change [slope], which is a vertical line. This is not a function, since it flunks the vertical line test.

Choose the equation of a circle with radius 6 and center (2, -3).

Rufina [12.5K]

Answer: $(x-2)^2 + (y+3)^2 = 36\\\\$

Work Shown:

$(x-h)^2 + (y-k)^2 = r^2\\\\(x-2)^2 + (y-(-3))^2 = 6^2\\\\(x-2)^2 + (y+3)^2 = 36\\\\$

Note that (h,k) = (2,-3) is the center and r = 6 is the radius. The last line is not expanded out using the FOIL rule because its common practice to leave it in $(x-h)^2 + (y-k)^2 = r^2\\\\$ form. This form allows the reader to quickly determine the center and radius (rather than have to do a lot of algebraic steps before hand).

What is the perimeter of the triangle expressed as a polynominal?

Oksi-84 [34.3K]

To find the perimeter you would add up all of the sides, so:
5x - 2 + 3x + 4 + x - 10
Now you combine the like terms
5x + 3x + x = 9x
-2 + 4 - 10 = -8
So your final answer is C) 9x - 8. I hope this helps!

Answer:

D. 105 students and 150 guests

Step-by-step explanation:

105 students and $1 for each ticket is $105.(105 x 1 = 105)

150 guests and $5 for each ticket is $750.(150 x 5 =750)

$105 + $750 = $855
