To prove that tan(u - v) does not equal tan u - tan v, we start by assuming values for u and v.
To do this, we assume the following values
So, we have:
Substitute the assumed values for u and v
Subtract 45 from 75
Using a calculator, calculate the values of tan(30), tan(45) and tan(75)
So, we have:
Subtract 1 from 3.7321
Notice that the expression on the left-hand side and the expression on the right-hand side are not equal.
Hence, is true

Answer:
Table A and Graph B
Step-by-step explanation:
It is Graph B because of the equation's slope which is 3. This 3 is represented as as a slope or as a "rise over run", this means that the graph goes up by 3 units while going right by 1 unit.
It is Table A because the points in the graph match with the points which Graph B goes through.

Step-by-step explanation:
If there is a solution between x = 1.1 and x = 1.2 then there will be a change in sign when the equation is evaluated at the points, indicating the graph has crossed the x- axis, where the solution lies.
Given
x³ + 4x = 6 ( subtract 6 from both sides )
x³ + 4x - 6 = 0 ← in standard form
Evaluating for x = 1.1
(1.1)³ + 4(1.1) - 6
= 1.331 + 4.4 - 6 = - 0.269 ← < 0
Evaluating for x = 1.2
(1.2)³ + 4(1.2) - 6
= 1.728 + 4.8 - 6 = 0.528 ← > 0
Since there is a change in sign the graph has crossed the x-axis from below / indicating a solution between x = 1.1 and x = 1.2
