Answer:
the answer is c
Step-by-step explanation:
just is.
Answer:
(-1, -9)
Step-by-step explanation:
Recall that for 2 points (x1, y1) and (x2,y2)
the midpoints are given by
x ordinate = 
y ordinate = 
In our case x1 = 8, y1 = -10, x2 = -10, y2=-8
x ordinate = = [8 + (-10) ] / 2 = -1
y ordinate = = [-10 + (-8) ] / 2 = -9
hence midpoint is (-1, -9)
You would have to do distribution you would do 5(2x) which would give you 10 and 5(10) which gives you 50 so your equation would be -60=10x+50 then you would subtract 50 from both sides which would give you -110 your equation would be -110=10x divided 10 on both sides and your answer would be x=-11
Congruence Properties
In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!
The Reflexive Property of Congruence
The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.
