Find the standard equation of the circle defined by the equation x^2 + y^2 +8x - 12y + 43 = 0. ANSWERS ATTACHED, due in 2 HOURS,
puteri [66]

Answer:

Solution: Option C

Step-by-step explanation:

Our goal here is to factor the expression such that it is converted into the circle equation (x - a)² + (y - b)² = r² where r = radius centered at point (a,b).

x^2\:+\:y^2\:+8x\:-\:12y\:+\:43\:=\:0 (Factor the expression "x² + 8x")

x^2+8x = x\left(x+8\right) (Factor the expression "y² - 12y")

\:y^2-12y =y\left(y-12\right)

That leaves us with the expression \left(x-\left(-4\right)\right)^2+\left(y-6\right)^2=3^2, or in other words (x+4)^2 +(y-6)^2 = 9. As you can see our solution is option c.

Solve for x.<br><br> 1/4 |12 - 4xl &lt; 5/2 - 2x
sergey [27]

Answer: X < 0.25.

Step-by-step explanation:

1. The absolute value of 2 - 4x would be the same as 2 + 4x.

2. Multiply 2 by 1/4. 1/4 of 2 would be 0.5

3. 5/2 is the same as 2.5.

4. Move the variables to one side and the numbers to the other side. In this case, move 0.5 to the opposite side of the <, making it -0.5. The right side of this problem should be 2.5 - 0.5. Do the same with move -2x to the other side, making it +2x. 4x + 2x is 6x.

5. The problem should now be 6x < 1.5. Divide each side by 6.

6. x < 0.25
