<h2>Answer:</h2>

<u>Given points are</u>,

A = (-4,6)

B = (6,6)

C = (6,2)

<u>To find out the circumcenter we have to solve any two bisector equations and find out the intersection points</u>.

<u>So, mid point of AB</u> = [(- 4 + 6)/2, (6 + 6)/2] = (1, 6)

<u>Slope of AB</u> = [(6 − 6)/(6 + 4)] = 0

<u>The slope of the bisector is the negative reciprocal of the given slope</u>.

<u>So, the slope of the perpendicular bisector</u> = 0

<u>Equation of AB with slope 0 and the coordinates (1, 6) is</u>,

(y + 4) = 1(x – 6)

x – y = - 2……………(1)

<u>Similarly, for AC</u>

<u>Mid point of AC</u> = [(- 4 + 6)/2, (6 + 2)/2] = (1, 4)

<u>Slope of AC</u> = [(2 − 6)/(6 + 4)] = - 4/10

<u>The slope of the bisector is the negative reciprocal of the given slope</u>.

<u>So, the slope of the perpendicular bisector</u> = 10/4

<u>Equation of AC with slope 10/4 and the coordinates (1, 4) is</u>,

(y + 4) = -1(x – 4)

y – 3 = -x + 4

x + y = 7………………(2)

<u>By solving equation (1) and (2)</u>,

(1) + (2) ⇒ 2x = 10;

Or, x = 5

<u>Substitute the value of x in to (1)</u>

3 – y = -1

y = 3 + 1 = 4

Thus, the circumcenter is (5, 4).

Solve the system of equations algebraically.<br><br> {Y=(x-2)^2+2<br> {Y+4=3x
nikdorinn [45]

Answer:

(5, 11) and (2, 2)

Step-by-step explanation:

y = (x-2)² + 2

y + 4 = 3x

(x-2)² + 2 + 4 = 3x

x² - 4x + 4 + 6 = 3x

x² - 7x + 10 = 0

(x - 5)(x - 2) = 0

x - 5 = 0, x = 5

x - 2 = 0, x = 2

y = (5-2)² + 2 = 11

(5, 11)

y = (2-2)² + 2 = 2

(2, 2)

Tems11 [23]

Answer: (p x 6)+8.88= $9.78

Step-by-step explanation:

multiply 0.15 by 6

6 x 0.15= 0.90

add that to 8.88 and you get $9.78

Answer:

ok so here is the answer:  n

hk

b

a

х

V

Angle a = 126. What is the measure of angle b? Explain how you calculated your answer.

Angle a = 126 Write an equation(s) in terms of b to find the measure of angle h.

Calculate the measure of angle h, using the equation(s) you wrote for Part B.

How would knowing the measure of angle y change the equation(s) you wrote in Part B to find the measure of angle h?

2021 Muminate Education Inc Your input: factor x2+4x+3.

To factor the quadratic function x2+4x+3, we should solve the corresponding quadratic equation x2+4x+3=0.

Indeed, if x1 and x2 are the roots of the quadratic equation ax2+bx+c=0, then ax2+bx+c=a(x−x1)(x−x2).

Solve the quadratic equation x2+4x+3=0.

The roots are x1=−1, x2=−3 (use the quadratic equation calculator to see the steps).

Therefore, x2+4x+3=1(x+1)(x+3).

(x2+4x+3)=1(x+1)(x+3)
