Answer:
a
Step-by-step explanation:
-11x² + 2x = 10
-11x² + 2x - 10 = 10 - 10
-11x² + 2x - 10 = 0
x = <u>-(2) +/- √((2)² - 4(-11)(-10))</u>
2(-11)
x = <u>-2 +/- √(4 - 440)</u>
-22
x = <u>-2 +/- √(-436)
</u> -22<u>
</u>x = <u>-2 +/- 2i√(109)
</u> -22
x = <u>-2 + 2i√(109</u>) x = <u>-2 - 2i√(109)</u>
-22 -22
x = ¹/₁₁ - ¹/₁₁i√(109) x = ¹/₁₁ + ¹/₁₁i√(109)

Answer:
x = -0.2
Step-by-step explanation:
2.3x+0.37 = 0.7x+0.05
Subtract 0.7x on both sides
1.6x + 0.37 = 0.05
Subtract 0.37 on both sides.
1.6x = -0.32
Divide by 1.6 on both sides to isolate the variable x
x = -0.2
The slope is -1/2 or -0.5
