Point m is the midpoint of kL. M(1,-1) and L(8,-7. What are the coordinates of point k?

Phoenix [80]

Answer: (-6, 5)

<u>Step-by-step explanation:</u>

Use the Midpoint Formula: $\dfrac{(x_k, y_k)+(x_L,y_L)}{2}=(x_m, y_m)$

Separate the x's and y's and solve them individually:

$\dfrac{x_k+x_L}{2}=x_m\qquad \qquad \qquad \qquad\dfrac{y_k+y_L}{2}=y_m\\\\\\\dfrac{x_k+8}{2}=1\qquad \qquad \qquad \qquad \qquad \dfrac{y_k-7}{2}=-1\\\\\\x_k+8=2\qquad \qquad \qquad \qquad \qquad y_k-7=-2\\\\\\x_k\quad =-6 \qquad \qquad \qquad \qquad \qquad y_k\qquad =5$

So, the k-coordinate is (-6, 5)

Find the solution to the system of equations. 4x + 3y = –1 3x – 9y = 33

alexandr1967 [171]

Answer:

Step-by-step explanation:

4x + 3y = -1 --------------(i)

3x - 9y = 33 -------------(ii)

multiply equation (i) by 3

(i)* 3 12x + 9y = -3

(ii) <u> 3x - 9y = 33</u>

add, 15x = 30

x = 30/15

x = 2

Put x =2 in Equation (i)

4*2 + 3y = -1

8 +3y = -1

3y = -1-8

3y = -9

y = -9/3

y= -3
