First find the x and y values because where the lines will intersect, they share the point of the intersection so they will share the x and y coordinates.
Rearrange equations


To cancel y, we must do equation 1 minus equation 2. Similarly:




So the x coordinate is 3.
The y coordinate can be found with substitution of x into one of the equations:

So where the two lines intersect is at the point (3, 7), which is the solution to the equations.
The answer you are looking for is 3.
To find this, you must first distribute the 3 into the parenthesis. 3 x 9 = 27 and 3 x 4 = 12.
Next, you subtract 12 from 27. 27 - 12 = 15.
Finally, divide 15 by 5 to get your final answer as 3.
I hope this helps!
-7x+3 (hope this is the answer you are looking for)
Answer:
85
Step-by-step explanation:
1/2(6x5) = 15
15x4 = 60
5x5= 25
25 + 60 = 85
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)
