Answer:
By using the 90 degree clockwise rotation formula, we are able to determine that the answer is (7, 6)
Step-by-step explanation:
The formula for 90 degree clockwise rotation is
(x,y)--->(y,-x)
The reason why our -6 turns into a positive is because the negative was replacing that negative therefore making it positive.
Hope this helps!
I'll leave the rest of the formulas I have in my notes for you!
180 degree rotations
(x,y)--->(-x,-y)
90 degree counterclockwise
(x,y)--->(-y,x)
270 degree rotation
(x,y)--->(y,-x)
Answer:
78
Step-by-step explanation:
plug in -3 as x
6(2(-3)^2-5)
6(2(9)-5)
6(18-5)
6(13)
78
+2,+2,+2,-2,-2,-2,+2,+2,+2 etc
Answer:
yes
Step-by-step explanation:
try using a vertical line, if you move the vertical line across the graph and the line touches the graph only at one point, than it means it is a function
Supposse that the distance from the point 
to the point 
is equal to the distance from to the point 
. Then, by the formula of the distnace we must have
cancel the square root and the 
's, and then expand the parenthesis to obtain
then, simplifying we obtain
therfore we must have
this means that the points satisfying the propertie must have first component equal to 5. So we can give a lot of examples of such points: 
. The set of this points give us a straight line and the points (3,0) and (7,0) are symmetric with respect to this line.
