The Degree<span> (for a polynomial with one variable, like </span>x<span>) is the largest exponent of that variable.
Let's check each terms :
</span>
<span> has degree of 4 (x is an exponent of 1, y has 2, z is an exponent of 1. So 1+2+1 = 4).
</span>
has a degree of 5 (z has an exponent of 5).
has degree 6 ( y has 2 and z has 4. So 2+4=6).
<span>
Now that we have checked each terms, we know that t</span><span>he largest degree is 6, so the polynomial has a degree of 6.
</span><span>
In short, your answer be 6.

Answer:
Option (C)
Step-by-step explanation:
There are two inequalities,
t - 4 ≥ 4t + 8 ------(1)
3t > 14 - 4t ------(2)
By simplifying inequality (1),
t - 4 ≥ 4t + 8
t ≥ 4t + 8 + 4
t ≥ 4t + 12
t - 4t ≥ 12
-3t ≥ 12
t ≤
t ≤ -4
By solving inequality (2),
3t > 14 - 4t
3t + 4t > 14
7t > 14
t >
t > 2
From the given graphs, Option (C) will be the answer.
