Answer:
Step-by-step explanation:
Are you sure you wanted that "b" in the second equation?
If so, here's how we eliminate y:
1) Multiply the first equation by b: 8bx + 3by = 2b
2) Multiply the second equation by 3: 12x - 3by = -21
3) Combine these two results. We get:
(8b + 12)x = 2b - 21
Here we have eliminated y, but still have an equation in two variables, b and x.
Answer:
(1, - 3 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ), thus
T(- 3, - 1 ) → T'(1, - 3 )
