Answer:

s = 6

Step-by-step explanation:

Given: -2s + 8(9 - s) = 3 - (9 - 3s)

Get rid of the brackets by using the distributive property:

-2s + 72 - 8s = 3 - 9 + 3s

You can rearrange the items so the expression is easier to solve:

-2s - 8s + 72 = 3s + 3 - 9

Combine like terms:

-10s + 72 = 3s - 6

Now let's subtract 72 from both sides of the expression:

-10s = 3s - 78

Next, subtract 3s from both sides of the expression:

-13s = -78

Lastly, divide each side of the expression by -13 to get:

s = 6

Find the center of the circle that you can circumscribe about DABC.

Vlada [557]

The center of the circle that circumscribe about DABC is $(h,k) = (1, 5)$ .

A circle can be modelled after a expression of the form:

$A\cdot x + B\cdot y + C =-x^{2}-y^{2}$ (1)

We can determine all coefficients by knowing three <em>distinct</em> points on plane.

If we know that $(x_{1}, y_{1}) = (2, 8)$ , $(x_{2}, y_{2}) = (0, 8)$ and $(x_{3}, y_{3}) = (2, 2)$ , then the solution of the system of linear equations is:

$2\cdot A + 8\cdot B + C = -68$ (2)

$8\cdot B + C = -64$ (3)

$2\cdot A + 2\cdot B + C = -8$ (4)

$A = -2, B = -10, C = 16$

Now we proceed to <em>complete</em> squares and factor each resulting perfect square trinomial in order to determine the coordinates of the center of the circle:

$x^{2}+y^{2}-2\cdot x -10\cdot y +16 = 0$

$(x^{2}-2\cdot x +1)-1+(y^{2}-10\cdot y +25)-25 +16 = 0$

$(x-1)^{2}+(y-5)^{2}= 10$

The center of the circle that circumscribe about DABC is $(h,k) = (1, 5)$ .

Hello, help me find the x-intercept. Please state the answer and explain how you got it. Thank you.

babunello [35]

Answer:y intercept is -2

Step-by-step explanation:

Because the equation line formula

Y=mx+b

Where m is slope and b is y- intercept

Therefore

Y=-4x-2

Your b is the -2
