Answer:
Hi this sentence doesnt make sense
Step-by-step explanation:
A few ways. you can enter it into a calculator for one, but the easiest way would be to reference a unit circle and look for an ordered pair where sin (the y value), is equal to -1/2
on a unit circle, the sin value is -1/2 at 7pi/6 and 11pi/6
because sin is the y value, it will additionally be in the quadrants III or IV based on the fact that (-1/2) as a sin value IS a negative and would have to be found in a quadrant in which sin is negative (the lower half of a coordinate plane, in this case)
you first have to solve the parentheses which is
20-13=7
then add 11 to the number you get from the parentheses
11+7= 18
your final answer should be
=18
In this equation the q is 12/17 and the r is 3/8 so if I am correct the answer is 9/34 hope this helps.
Answer:
x=-2, y=-2. (-2, -2).
Step-by-step explanation:
2x-5y=6
-2x+10y=-16
-------------------
5y=-10
y=-10/5=-2
2x-5(-2)=6
2x+10=6
2x=6-10
2x=-4
x=-4/2=-2
