We have an inscribed angle here. Angle YXZ is an inscribed angle.
Angle YXZ can also be expressed as simply angle x but I will use angle YXZ.
Angle YXZ = (1/2)(arc YZ)
Angle YXZ = (1/2)(144°)
Angle YXZ = 72°
Done!
All you have to do is plug in the x and y values for each ordered pair into the left hand side of the equation and see if you get 15 = 15. If you do, the ordered pair is a solution; otherwise it is not a solution. For example, let's try (-2,-3); that is x = -2 and y = -3:
2x - 9y = 15
2(-2) - 9(-3) = 15
-4 - (-27) = 15
-4 + 27 = 15
23 = 15
This is obviously not true, so (-2,-3) is not a solution. Now you try it on each of the ordered pairs given in the problem statement.
Answer:
5 is your answer
Step-by-step explanation:
Isolate the x. Note the equal sign, what you do to one side, you do to the other. Multiply 24 to both sides
(x/24)(24) = (0.2083)(24)
x = (0.2083)(24)
Simplify
x = 4.9992
Round to the nearest hundredths place (underlined & bolded): 4.9<u>9</u>92
Look at the number to the right of the hundredths place. It is a 9. Because 9 is greater than 5, round up
4.9992 rounded to the nearest hundredth place = 5
