Complete the square to rewrite the following equation. Identify the center and radius of the circle. You must show all work and

Sliva [168]

Answer:

( x+1)^2 + (y+2)^2 = 25

The center is (-1, -2) and the radius is 5

Step-by-step explanation:

x^2 + 2x + y^2 + 4y = 20

Complete the square

2/2 =1 1^2 =1 so add 1 for x 4/2 =2 2^2 = 4 so add 4 for y

x^2 +2x +1 +y^2 +4y+4 = 20 +1 +4

( x+1)^2 + (y+2)^2 = 25

(x+1) ^2 + (y+2)^2 = 5^2

(x - -1) ^2 + (y - -2)^2 = 5^2

This is in (x-h)^2 + (y-k)^2 = r^2 form where (h,k) is the center and r is the radius

The center is (-1, -2) and the radius is 5

Describe the error in the work shown.

mihalych1998 [28]

The error was in second step.

3√(y^3)^4 = y^4

(Cube root cancels cube and not power 4)

The answer should be:

xy^4/4

Y= -x^2+2x+1 <br>i need help understanding

Eddi Din [679]

Answer:

Does not factor; domain = -∞<x<∞, range = f(x) ≤ 2.

Step-by-step explanation:

Assuming your end goal is to factor the polynomial

$y=-x^{2} +2x+1$

If we use the guess and check method we can see that there is no way to factor this polynomial.

However, if you are looking for a domain and range we can graph it on a graphing calculator. Just by looking at the graph, we can see that the domain is all real numbers, or -∞<x<∞, and the range is f(x) ≤ 2.

I hope this helped!

Solve 2(b − 3) ≥ 3(3 − b) and describe the graph of the solution. Show all your work.

solong [7]

Answer:

$\large\boxed{b\geq3\to b\in[3,\ \infty)}$

Step-by-step explanation:

$2(b-3)\geq3(3-b)\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\(2)(b)+(2)(-3)\geq(3)(3)+(3)(-b)\\\\2b-6\geq9-3b\qquad\text{add 6 to both sides}\\\\2b-6+6\geq9+6-3b\\\\2b\geq15-3b\qquad\text{add}\ 3b\ \text{to both sides}\\\\2b+3b\geq15-3b+3b\\\\5b\geq15\qquad\text{divide both sides by 5}\\\\\dfrac{5b}{5}\geq\dfrac{15}{5}\\\\b\geq3$
