The answer to your question is X= 11
5.5 + 2.1x + 3.8x - 4.1
5.5-4.1 +x(2.1+3.8)
1.4 +x(5.9)
5.9x+1.4
these are equivalent if there is a plus sign between 1.4 5.9x
Answer: 11.2$
Step-by-step explanation:
You need to know:
Tangent function has range of <span>(-∞, ∞)
Sine function has range of [-1,1], which is the same as cosine function
So [-3,3] matches the 1st, [0,2] matches the 2nd, [-1,7] matches the 3rd, the 4th will be the rest </span>
