-12x² + 11x - 3 = 0
x = <u>-(11) +/- √((11)² - 4(-12)(-3))</u>
2(-12)
x = <u>-11 +/- √(121 - 144)</u>
-24
x = <u>-11 +/- √(-23)
</u> -24
x = <u>-11 +/- i√(23)</u>
-24
x = <u>-11 + i√(23</u>) x = <u>-11 - i√(23)</u>
-24 -24
x = ¹¹/₂₄ - 0.0416√(23) x = ¹¹/₂₄ + 0.0416√(23)

Answer:
x = 3
Step-by-step explanation:
To find the x-coordinate, substitute y = 8 into the equation abd solve for x
5x - 7 = 8 ( add 7 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Thus (3, 7) is a solution to the equation
Answer:
you want to isolat U on one side, so subtract 9/-4 from both sides to end up with (9/-4) - 9 = u, then solve. (9/-4)-9 = -11.25, so -11.25 = u
Answer:
Check the distance between the lines at several places with a compass to ensure they are equidistant.
Step-by-step explanation:
The distance between the parallel lines is always constant and they never intersect with each other.
So, to verify if the lines constructed are parallel, we can check the following:
Check the distance between the lines at several places with a compass to ensure they are equidistant.
