Answer:
A
Step-by-step explanation:
1/2r +1/2= -2/7r -29/7 Subtracting 1/2 from both sides
1/2r +1/2 - 1/2= -2/7r -29/7- 1/2
1/2r = -2/7r - 29(2)-7/14
1/2r = -2/7r -65/14
Both exponential i.e 5 ^x
A is true, surprisingly.
B cannot be true, it alternates.(rule of indices negatives by positive exponent = positive, negative by negative , but -5 x -5 x -5 = + 5)
I'm only imaginging, but C must be right, since it increases exponentially, as opposed to D which only increases quadratically.
What do you need help with?
Your answer would be the second option, (3a - 4)(a + 3).
We can see that this is the correct answer as if we expand it using FOIL, we get 3a² + 5a - 12:
(3a × a) + (3a × 3) + (-4 × a) + (-4 × 3) = 3a² + 9a - 4a - 12
= 3a² + 5a - 12.
I hope this helps!
I believe the answer would be 17, because 100, 210, 201, 301, 310, 401, 410, 501, 510, 601, 610, 701, 710, 801, 810, 901, 910
