Write the equation of the circle graphed below.
mojhsa [17]

Answer:

As shown in picture, this circle has radius 1.5 and passes (0, 1.5)

=> According to the general form of equation of circle that has radius r and passes (a, b): (x - a)^2 + (y - b)^2 = r^2, we have:

x^2 + (y - 1.5)^2 = 1.5^2

<=>

x^2 + (y - 1.5)^2 = 2.25

Hope this helps!

6(4x + 2) = 3(3x – 6).
timurjin [86]

Steps to solve:

6(4x + 2) = 3(3x – 6)

~Distribute

(6 * 4x) + (6 * 2) = (3 * 3x) + (3 * -6)

~Simplify

24x + 12 = 9x - 18

~Subtract 12 to both sides

24x + 12 - 12 = 9x - 18 - 12

~Simplify

24x = 9x - 30

~Subtract 9x to both sides

24x - 9x = 9x - 30 - 9x

~Simplify

15x = -30

~Divide 15 to both sides

15x/15 = -30/15

~Simplify

x = -2

Best of Luck!
