w-(-3)=7
Pretend that there is a -1 in front of the bracket
w-1(-3)=7
Mutiply the bracket by -1
(-1)(-3)=3
w+3=7
Move +3 to the other side. Sign changes from +3 to -3.
w+3-3=7-3
w=4
Answer: w=4
Answer:
C, B, A
Step-by-step explanation:
The sides in order from shortest to longest are ...
AB = m-2
AC = m
BC = m+4
The angles opposite these sides will be in order, smallest to largest. The angle opposite is the one whose letter is <em>not</em> in the line segment name.
C, B, A
Eddie: $10-3=$7
Marsha: $8+$3=$11
Answer:
y=3x+4
Step-by-step explanation:
since the line is parallel it has the same slope so we have y = 3x + b. plug in the point (2,10) to get 10 = 3*2 + b, so b=4. so the equation is y = 3x +4
Answer:
A transitive property
Step-by-step explanation:
There isn't much to this.
This is the the transitive property.
I guess I can go through each choice and tell you what the property looks like or postulate.
A) If x=y and y=z, then x=z.
This is the exact form of your conditional.
x is AB here
y is BC here
z is DE here
B) Segment Addition Postulate
If A,B, and C are collinear with A and B as endpoints, then AB=AC+CB.
Your conditional said nothing about segment addition (no plus sign).
C) Distributive property is a(b+c)=ab+ac.
This can't be applied to any part of this. There is not even any parenthesis.
D) The symmetric property says if a=b then b=a.
There is two parts to our hypothesis where this is only part to the symmetric property for the hypothesis .
