Answer:

#6- you can verify this way by plugging the value you got for x or y back into the equation. If it works, then the equation will be true.

By graphing- The solution on the graph is where the 2 lines will intersect. Find the coordinates of the intersection point and see if your answer has the same x and y values, if so, it is correct.

Answer:

Step-by-step explanation:

sum of exterior angles = 360

64 + 60 + 69 + 42 + x + x +23 = 360

2x + 258 = 360

2x = 360 - 258

2x = 102

x = 51

Answer:

The answer is (1/2)z - x - 3y

Step-by-step explanation:

∵ $log_{2}P=x$

∵ $log_{2}Q=y$

∵ $log_{2}R=z$

∵ $log_{2}\frac{R^{\frac{1}{2}}}{(P)(Q^{3})}$

∴ $log_{2}(R)^{\frac{1}{2}}-log_{2}P-log_{2}(Q^{3})$

∴ $\frac{1}{2}log_{2}R-log_{2}P-3log_{2}Q$

∴ $\frac{1}{2}z-x-3y$
