Step-by-step explanation:
Solution
= -3/2
= 2
Answer: 15/30 = 5/10
Step-by-step explanation: 5/10 = 1/2 so then you'd have to make 15/ something double it so It would equal 1/2 hope this helps :)
To find the answer, we need to find the coordinate of figure PQRS, but I will only find the coordinate of point P which is:
P(1,-3), and the coordinates of P'(-3,1)
First choice:
Counterclockwise rotation about the origin by 90 degrees followed by reflection about the x-axis
Counterclockwise rotation 90° means that rotate 270° clockwise, and the formulaa to find it is
270° Rotation
(x,y) to (-y,x)
Point P rotate 270° counterclockwise
(1,-3) to (3,1)
Reflection over x-axis formula is
(x,y) to (x,-y)
Do the same to point P
(3,1) to (3,-1) which is not right because the coordinate of point P is (-3,1) not (3,-1)
Just to save times
Let check the last one
Counterclockwise rotation about the origin by 90 degrees followed by reflection about the y-axis
We already have the coordinate of rotate 90° counterclockwise which is
(3,1)
Then, reflection over y-axis formula is
(x,y) to (-x,y), so
Point P'
(3,1) to(-3,1) which is right. As a result, Counterclockwise rotation about the origin by 90 degrees followed by reflection about the y-axis is your final answer. Hope it help!
Answer:
270.47625
Step-by-step explanation:
249 is the original price
(249/100) · 8.625 = 21.47625 the tax total
249 + 21.47625 = 270.47625
