Which is the location of S' when trapezoid RSTU is rotated 90° clockwise about the origin to produce trapezoid R'S'T'U? Explain.
1 answer:
Answer:
D. (12,3)
Step-by-step explanation:
From the graphical diagram attached below ; we would realize that the x-coordinate is in the positive direction and the y-coordinate is in the negative direction.
Initially, the location of S = 12 to the horizontal x axis from the graphical diagram. So, if the trapezoid RSTU is rotated 90° clockwise about the origin to produce trapezoid R'S'T'U, we will have :
S' = 3
Thus; the (x,y) coordinate of R'S'T'U = (12,3)

You need to find the change in x and y
change in x = 12
change in y = 16
to find the distance you use a^2+ b^2 = c^2
or in this case x^2 + y^2 = d^2
144+256 = 400
=20
so distance equals 20
I hope this helps!

Answer:
Step-by-step explanation:
The given system is
3x-2y=6
0.4(20y+15)=x
The slope intercept form is y=mx+c.
For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6
For 0.4(20y+15)=x, we expand to get:
Divide through by 8
Therefore the system in slope-intercept form is:
