The line with equation 4b + a = 0 coincides with the terminal side of an angle x in standard position in Quadrant IV.
nignag [31]
The equation of the line is
4b + a = 0

The slope of the line is
m = -1/4

With a rise of 1 and run of -4 which corresponds to a hypotenuse of
√(4² + (-1)²) = √17

Therefore, the sine of the angle is
sin θ = 1/√17<span />

2 3 − 5 6 ·8<br><br> Simplify.
Helga [31]

Answer:

-1.33 and so on

Step-by-step explanation:

Take each fraction and plug it into a calculator. 2/3 is really 2 divide by 3. Same with the 5 and 6. You should get 0.67 and so on for 2/3 and 0.83 and so on for the 5/6. Subtract as shown in the problem. You should get 0.67-0.83= -0.1666 so on. Multiply by 8 to get -1.33 and so on. The "and so on" means this decimal is repeating. Hope this Helps!
