You plug in 2 for the w and do 17 minus 2 and then you divide that by 3 so ur answer is going to be 17-2 which is 15 and then divide 15 by 3 and you get 5
The answer is A.
I only know how to explain by using the rule for reflection over x axis sorry.
The rule is (x,-y) x coordinate stays the same but you do the opposite for the y coordinate so -7.05 would be 7.05
Exact Form:
x
=
7
8
x
=
7
8
Decimal Form:
x
=
0.875
x
=
0.875
Sorry...I dont understand......
The area of a triangle is:
A=hb/2 where h=height and b=base
We can let the "height" be the horizontal magnitude, (x3-x1)
And the base would then be the vertical magnitude, (y2-y1)
So the area is:
A=(1/2)(y2-y1)(x3-x1)
