<u>ANSWER</u>

{(x + 10)}^{2}  + {(y + 6)}^{2} = 121

<u>EXPLANATION</u>

The equation of the circle in general form is given as:

{x}^{2}  +  {y}^{2}  + 20x + 12y + 15 = 0

To obtain the standard form, we need to complete the squares.

We rearrange the terms to obtain:

{x}^{2}  + 20x +  {y}^{2}  + 12y  =  -  15

Add the square of half the coefficient of the linear terms to both sides to get:

{x}^{2}  + 20x +100   + {y}^{2}  + 12y  + 36 =  -  15  + 100 + 36

Factor the perfect square trinomial and simplify the RHS.

{(x + 10)}^{2}  + {(y + 6)}^{2} = 121

This is the equation of the circle in standard form.

77 prime or composite
Ludmilka [50]

<u><em>Seventy-seven is a composite number. </em></u>

Because you had to divide by eleven or seven. Then you can multiply by seven or eleven its equal to seventy-seven.

77/11=7

11*7=77

77/7=11

7*11=77

Final answer: \boxed{=77}

Hope this helps!

Angles a and b are complementary angles symmetry of angle a is 28° more than the measure of angle b find the missing angle measu
scoray [572]

Answer:

31 , 59

Step-by-step explanation:

a = b +28

a + b = 90 {Complementary}

b + 28 + b = 90    {Combine like terms}

2b + 28 = 90       {Subtract 28 form both sides}

       2b  = 90 - 28

       2b = 62      {Divide both sides by 2}

        b = 62/2

       b = 31

a = 31 + 28

a = 59

Solve the following system of equations graphically on the set of axes below.
eimsori [14]

Answer:

  (x, y) = (3, 5)

Step-by-step explanation:

To solve these equations graphically, you plot each one, then identify the coordinates of the point of intersection.

The first equation can be graphed using the y-intercept of -1 and the slope of 2.

The second equation has a y-intercept of 18/3 = 6, and a slope of -1/3. The x-intercept of 18 is off the chart, so the slope and intercept are a good way to plot this line, too.

__

The slope is the "rise" divided by the "run". A slope of 2 means the line goes up 2 units for each unit to the right. A slope of -1/3 means the line goes down 1 unit for each 3 units to the right.

The solution is (x, y) = (3, 5).
