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
A^2-b^2=(a+b)(a-b)
1: x^2-4=(x+2)(x-2)
2: (x+8)(x-8)
3: (x+10)(x-10)
4: (x+14)(x-14)
I believe the answer is 2783 for 1 a - either
Answer: Your question is written f(x) = -2*(-3+3)+1. I'll assume you need the answer for just the one value of x (-3)? If so, f(-3) = 1.
Step-by-step explanation:
f(x) = -2*(-3+3)+1
f(x) = -2*(0)+1
f(x) = 1
Other values x for the equation f(x) = -2*(x+3)+1:
-2 is -1
1 is -7
3 is -11
