Answer:

A. The subtraction property of equality

Step-by-step explanation:

We have to find the rule applied to obtain line 3 from line 2.

Now, line 2 is -4x + 9 = 2x + 10 and line 3 is -6x + 9 = 10.

We can see that the only possible way to get line 3 from line 2 is by subtracting 2x from both the sides.

i.e.  -2x - 4x + 9 = -2x + 2x + 10

i.e. -6x + 9 = 10

Hence, the subtraction property of equality is the justification for getting line 3 from line 2.

Write the standard equation of a circle that passes through (-5 5) with center (-10 -5) brainly
timama [110]

Answer:

The equation of the circle is (x + 10)² + (y + 5)² = 125 in standard form

Step-by-step explanation:

* lets study the standard form of the equation of a circle

- If the coordinates of the center of the circle are(h , k) and its radius

 is r, then the standard equation of the circle is:

 (x - h)² + (y - k)² = r²

* Now lets solve the problem

∵ The coordinates of the center of the circle are (-10 , -5)

∵ The standard form of the equation is (x - h)² + (y - k)² = r²

∵ h , k are the coordinates of the center

∴ h = -10 , k = -5

∴ The equation of the circle = (x - -10)² + (y - -5)² = r²

∴ The equation of the circle = (x + 10)² + (y + 5)² = r²

- To find the value of the radius lets use the point (-5 , 5) to

  substitute their coordinate instead of x and y in the equation

∵ The circle passes through point (-5 , 5)

∵ (x + 10)² + (y + 5)² = r²

- Use x = -5 and y = 5

∴ (-5 + 10)² + (5 + 5)² = r² ⇒ simplify

∴ (5)² + (10)² = r²

∴ 25 + 100 = r²

∴ r² = 125

* Now lets write the equation in standard form

∴ (x + 10)² + (y + 5)² = 125

* The equation of the circle is (x + 10)² + (y + 5)² = 125 in standard form
