Janae found PointA located at ,(-2,5) and c is located at (6,1) . What would be the x coordinate of point b that bisects A and C
Alexxandr [17]

A point that bisects a segment would be its midpoint. This is a case where the vocabulary  (bisect as opposed to midpoint) makes it harder.

To find the midpoint, we use the midpoint formula. The midpoint formula is:

midpoint = (x₁ + x₂/2, y₁ + y/2). To find it, you add the x coordinates and then divide them by 2. Repeat for the y coordinates.

x: (-2 + 6)/2 = 4/2 = 2

y: (5 +1)/2 = 6/2 = 3


Thus the point B bisecting AC is at (2, 3).

What are the solutions to the system of equations <br> {-x+y=4<br> {y+12=x^2+x
Gnoma [55]

Answer:

Step-by-step explanation:

y=4+x          ............................................ (1)

y=x^2+x-12  ............................................ (2)

now equate both (1) and (2)

4+x=x^2+x-12

=>x^2=16

x=-4,4

now substitute the values of x ,

when x=-4 , y becomes 0

when x=4  , y becomes 8

so, solution set:

(-4,0) and (4,8)
