Answer:
B (2 violet)
Step-by-step explanation:
Let the colors be represented by their first letter. Then the balances give rise to two equation:
o +y +b +v = r +g +b
o +y +v = g +v
Subtracting the second equation from the first gives ...
(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)
b = r +b -v
Adding v-b to both sides, we have ...
b +(v -b) = r +b -v +(v -b)
v = r
Multiplying this result by 2, we can match the final balance:
2r = 2v . . . . . . . choice B
F(x) = -3x - 2
f(-5) = -3(-5) -2 = 15 - 2 = 13
F(x)=(x-10)^2
Right is negative
Left is positive
Remember that - those become handy later on. Try to become really good at transformations!
Good luck!
