Answer:
C. G' (4,-7), R' (2,-3), T'(6,-4)
Step-by-step explanation:
Get a piece of paper and draw 2 intersecting lines, like how a graph looks like. Then get another paper that's transparent enough, and place a dot roughly where R would be. Rotate it 270* clockwise (3 times around 90 degrees), and R would be in the bottom right area. That means the figure would be around that area and you can base the coordinates from that.
Answer:
A, B, C and D. are solutions.
Step-by-step explanation:
x^2 + y^2 = 13
x^2 - y^2 = 5
Check which roots fit the original equations:
If x = 3, A gives
9 + y^2 = 13 giving y = +/- √4 = 2 or -2.
Now plug in x = 3 and y = 2 in the second equation:
9 - (2)^2 = 5
Therefore (3,2) is a solution of the 2 equations.
Following the same procedure for B, C and D:
B. Substituting x = 3 and x = -2 fits both equations so (3, -2) is a solution.
The same is true for C and D.
(480/1600)×100=30
Or
(480×100)/1600=30
