M is the midpoint of JK. The coordinates of J are (6,3) and the coordinates of M are (-3,4), find the coordinates of K.

(-12, 5) is the point K
To get the x coordinate, you have to see how far you went from J to M in the x-directioon. -3 - 6 = -9 so to go on to K subtract 9 again -3 - 9 = -12 for the x

Do the same for the y-coordinate
4 - 3 = 1 so add 1 again
4 + 1 = 5
Thus the point (-12, 5)

Two angels of a triangle measure 65 and 75. Which is not the measure of an exterior angle of the triangle

Andre45 [30]

An exterior angle is the sum of the two other interior angles

<span>the three interior angles are 55 and 65 and 180-(55+65)=60 </span>

<span>so 60 + 55 = 115 </span>
<span>60 + 65 = 125 </span>
<span>65 + 55 = 120

Jennifer's saving to buy a bike. The bike costs $245. She has $125 saved, and each week she adds $15 to her savings. How long wi

Novosadov [1.4K]

It will take her 8 weeks to save up enough money for the bike.

To get the answer first you have to subtract 125 from 245 to see how much money she still has to save then divide the answer which is 120 by 15 and you get 8. Hope this helps!!

Find an equation for the line that passes through the points (1, -1) and (-3, 1).

saul85 [17]

Answer:

Step-by-step explanation:

Equation of line is y = mx + c

where m is the slope

c is the y intercept

Slope of the line using points

(1, -1) and (-3, 1) is

$m = \frac{1 + 1}{ - 3 - 1} = - \frac{2}{4} = - \frac{1}{2}$

Equation of the line using point

( 1 , - 1) and slope - 1/2 is

$y + 1 = - \frac{1}{2} (x - 1) \\ y + 1 = - \frac{1}{2} x + \frac{1}{2} \\ y = - \frac{ 1}{2} x + \frac{1}{2} - 1 \\ y = - \frac{1}{2} x - \frac{1}{2}$

Hope this helps you.
