The easiest way to solve this problem is by using the Pythagorean theorem :D
Pythagorean theorem: [-b +- sqrt(b^2 - 4ac)]/2a
5 = a
-1 = b
6 = c
therefore, by plugging these values in!
[-(-1) +- sqrt((-1)^2 - 4(5)(6))]/2(5)
[1 +- sqrt(1 - 120)]/10
Oh so we're using imaginary numbers, so in this case you'll need to know that i = sqrt(-1), so keep this in mind (I can see why this was so difficult)
[1 +- sqrt(119)*i]10
answers:
( 1 + i*sqrt(119) ) / 10
( 1 - i*sqrt(119) ) / 10
If you solve for x answer is x=y/5+7/5
The slope of line AB, BC, CD and AD are 1, -1/6, 2, -4/6 respectively. Quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C
<h3>How to determine the slope</h3>
Formula for slope is given as;
Slope =
A(-4 -1)
B(-1 2)
C(5 1)
D(1 -3)
a. Slope of line AB = = = = 1
b. Slope of line BC = =
c. Slope of line CD = = = 2
d. Slope of line AD = =
Quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C
Thus, the slope of line AB, BC, CD and AD are 1, -1/6, 2, -4/6 respectively.
and quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C

Answer:
Step-by-step explanation:
we know that
Triangles ABC and CDE are similar triangles, because the corresponding angles are congruent
------> by vertical angles
----> given problem
----> The sum of the internal angles of the triangle must be equal to degrees
we have
so
Answer:
615
Step-by-step explanation:
6150 x 10%
6150 x 0.10 = 615
