Answer:
M = (13, - 6 )
Step-by-step explanation:
The coordinates of the midpoint are the average of the x and y coordinates of the endpoints.
L (- 9, 4 ) , let M = (x, y ) , then
= 2 ( multiply both sides by 2 )
- 9 + x = 4 ( add 9 to both sides )
x = 13
and
= - 1 ( multiply both sides by 2 )
4 + y = - 2 ( subtract 4 from both sides )
y = - 6
Then
coordinates of M = (13, - 6 )
I'm going with 11.56. Let me know? 10.63 isn't that to the nearest hundredth.
Answer:
y=1/2x-3
Step-by-step explanation:
1) Find slope... (y2-y1)/x2-x1–> (-4-(-1))/-2-4=-3/-6=1/2
2) Pick a coordinate and plug into equation y-y1=m(x-x1)—> y-(-1)=1/2(x-4)
3) Simplify to make y alone —> y=1/2x-3
Answer:
Step-by-step explanation:
The formula to finding a discriminant would be b^2-4ac, the b value of this trinomial being -5, the a value being 2, the c value being 3. Then, you plug the values in the equation and solve: (-5)^2-4(2)(3)
This would simplify to 1, meaning there are two solutions since the discriminant value is positive. If it is 0, there is one solution, if it is negative, then there are no real solutions.
