Answer: C) 4
==========================================================
Explanation:
Let's isolate t
-3 > -3t + 6
-3+3t > 6
3t > 6+3
3t > 9
t > 9/3
t > 3
This means any value can replace t such that it's larger than 3.
Something like t = 1/3 = 0.33 won't work since it's not larger than 3.
But something like t = 4 would work because it makes t > 3 true.
That's why choice C is the final answer.
We can find roots by setting f(x) = 0 --> x^4 - x^3 - 13x^2 + x + 12 = 0.
Factoring f(x) to make things easier for us gives us (x - 1)(x + 1)(x - 4)(x + 3), which, equal to 0, gives us the ability to set each set of parentheses = 0.
x - 1 = 0 gives us x = 1.
x + 1 = 0 --> x = -1.
x - 4 = 0 --> x = 4.
x + 3 = 0 --> x = -3.
our roots are x = 1, -1, 4, and -3.
Answer:
Step-by-step explanation:
-w(2+5)
W is like term
<span>4.110, or 4.11 is greater than 4.10 because there is an additional hundredth. This makes it bigger by a hundredth — it is not a lot greater than 4.10, but it is greater than 4.10.</span>
**Remember this rule: the sum of a triangle's angle measurements always = 180
So 2x + 3x + 4x = 180
9x = 180
9x/9 = 180/9
x = 20
A) 20
