Answer:
(4,3)
You didn't list if it was clockwise or counterclockwise, so I will just assume that you were asking for clockwise.
Step-by-step explanation:
If it is a 270 degree rotation cw, then it changes from (x,y) to (y,-x).
(-3,4) ---> (4,3)
Let's use the addition/subtraction method.
Suppose we wish to eliminate variable x.
Mult the first eqn by 5: 10x - 15y = 15
Mult the 2nd eqn by -2: -10x+ 4y = -8
Add these two equations together: -11y = 7, and y = -7/11.
Subst. -7/11 for y in either given equation and find x.
Then your solution is (x,y) (subst. the values we've found for x and y).
Answer:
SAS Postulate
Step-by-step explanation:
You can use the SAS (side, angle, side) postulate that says "if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent"
Side AB is proportionate to DE and
Side AC is proportionate to DF.
Angle A and Angle D are the same; and is between the two sides
I hope this helps.
There is 10,000 possible combinations for the numbers 0-9
GM = 1/2(GH)
7x + 2 = 1/2(32)
...multiply 1/2
7x + 2 = 16
...subtract 2
7x = 14
...divide 7
x = 2
GM = 7(2) + 2 = 16
MH = GM, so it is also 16
