Answer:

Simplifying

4x + 9 = 12x + -3

Reorder the terms:

9 + 4x = 12x + -3

Reorder the terms:

9 + 4x = -3 + 12x

Solving

9 + 4x = -3 + 12x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12x' to each side of the equation.

9 + 4x + -12x = -3 + 12x + -12x

Combine like terms: 4x + -12x = -8x

9 + -8x = -3 + 12x + -12x

Combine like terms: 12x + -12x = 0

9 + -8x = -3 + 0

9 + -8x = -3

Add '-9' to each side of the equation.

9 + -9 + -8x = -3 + -9

Combine like terms: 9 + -9 = 0

0 + -8x = -3 + -9

-8x = -3 + -9

Combine like terms: -3 + -9 = -12

-8x = -12

Divide each side by '-8'.

x = 1.5

Simplifying

x = 1.5

Whats the equation for this​
yawa3891 [41]

Answer:

x^2 + y^2 + 4x + 4y  = -119/16

Step-by-step explanation:

The axes x and y are calibrated in 0.25

If the circle is carefully considered, the radius r of the circle is:

r = -1.25 - (-2)

r = 0.75 units

The equation of a circle is given by:

(x - a)^2 + (y - b)^2 = r^2

The center of the circle (a, b) = (-2, -2)

Substituting  (a, b) = (-2, -2) and r = 0.75 into the given equation:

(x - (-2))^2 + (y - (-2))^2 = (3/4)^2\\\\(x + 2)^2 + (y + 2)^2 = (3/4)^2\\\\x^2 + 4x + 4 + y^2 + 4y + 4 = 9/16\\\\x^2 + y^2 + 4x + 4y + 8 = 9/16\\\\16x^2 + 16y^2 + 64x + 64y + 128 = 9\\\\16x^2 + 16y^2 + 64x + 64y  = -119\\\\x^2 + y^2 + 4x + 4y  = -119/16\\
