PLZ HELP ASAP CIRCLES

Mathematics
1 answer:
love history [14]3 years ago
4 0
First we need to convert the given equation to standard form, then we can write the center and radius directly from it.

x^{2} -16x+ y^{2} -36=0 \\  \\ 
 x^{2} -2(x)(8)+ y^{2} = 36 \\  \\ 
 x^{2} -2(x)(8)+ 8^{2}+  y^{2} =36 +8^{2} \\  \\ 
(x-8)^{2}+y^{2}=100

Thus, we can say now:

Center of the circle is (8,0) and its radius is 10.

Is each expression a polynomial? Drag and drop each expression to the correct box. Is a polynomial Is not a polynomial 2x−6 2x^2
Varvara68 [4.7K]

Alright , lets get started.

A polynomial can have constants, variables or exponents that can be combined using addition, subtraction, multiplication and division but not division by a variable.

2x - 6 : Polynomial

2x^2 -6x+4 : Polynomial

\frac{2}{3}x^4-6x^3+4x : Polynomial

2x^{-2}-6x+4 = \frac{2}{x^2}- 6x + 4 : Not Polynomial because it has a variable in division.

Hope it will help :)

A student is trying to solve the system of two equations given below:
levacccp [35]

Answer: B: (y + z = 6) × -5

Step-by-step explanation:

if you multiply 'y' by -5 it turns into -5y. Therefore when you add -5y and 5y together, you get 0y which is what you want when eliminating the y-term.
