Answer:
The midpoint of this line segment is (-1.5, -4.5).
Step-by-step explanation:
In finding the midpoint of a line segment we are actually averaging the x- and y-coordinates of the endpoints:
-2 -1
x-coordinate of midpoint = --------- = -3/2 = -1.5
2
-4 -5
y-coordinate of midpoint = ---------- = -4.5
2
The midpoint of this line segment is (-1.5, -4.5).
Answer:
a = 5
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle
a² + 12² = 13²
a² + 144 = 169 ( subtract 144 from both sides )
a² = 25 ( take the square root of both sides )
a =
= 5
Answer:
b option is the weight answer I think.
Answer:
16
Step-by-step explanation:
The equation is X2 – 19x + 48 = 0
Using the quadratic formula
X= - b +- √ ( b^2 - 4ac)/ 2a
Where a= 1 b= -19 c= 48
Substitute into the formula we have
