Hello from MrBillDoesMath!
Answer:
x > -7/3
Discussion:
-3x + 8 < 15 => add 3x to both sides
(-3x + 3x) + 8 < 15 + 3x => (-3x + 3x) = 0
8 < 15 + 3x => subtract 15 from both sides
8-15 < 3x => 8 - 15 = -7
-7 < 3x => divide both sides by 3
-7/3 < x
Thank You,

Step-by-step explanation:
the answer is 14,880 and its bigger :D 14880>12400
C) p(x) has a zero between x=2 and x=4
For a polynomial p(x), means that, when p(x) is divided by , the remainder is .
This is called the remainder theorem
Therefore , means that when p(x) is divided and is 1 and respectively.
Also the Intermediate value theorem says that, if p(a) and p(b) have opposite signs then there is a certain on where i.e there is a zero between and
Therefore the correct answer is C
the right answer would be 13
b = (c - 3a)/4
3a + 4b = c
4b = c - 3a
