Solve - 2x - 8> 3x + 12.
Please help!
Answers
Answer:
B. X < -4
Step-by-step explanation:
-2x - 8 > 3x + 12
Subtract 3x from both sides
-5x -8 > 12
Add 8 both sides
-5x > 20
Divide -5 both sides
X < -4
Answer: x < -4
Step-by-step explanation:
Subtract 3x from both sides
-5x - 8 > 12
Add 8 to both sides
-5x > 20
Divide both sides by -5
x < -4

x(6 + 2i) = 1
x = 1/(6 + 2i) = (6 - 2i)/(6 + 2i)(6 - 2i) = (6 - 2i)/(36 - 12i + 12i + 4) = (6 - 2i)/40
(6 + 2i) (6 - 2i) = 36-12i+12i-4i^2
As i^2= -1 . So ,
= 36+4
= 40
So 40 +is the correct answer.

The answer to your question is Midpoint = (-1.5, -2.5)
Step-by-step explanation:
Data
Point A = (-5, 2)
Point B = (2, -7)
Process
To find the midpoint, use the formula to calculate the mid-x and the formula to find the mid-y, then write the results as a point.
Formula
Xm = (x1 + x2) / 2
Ym = (y1 + y2) / 2
Substitution
Xm = (-5 + 2)/2
Ym = (2 - 7)/2
Simplification
Xm = -3/2
Ym = -5/2
Result
Xm = -1.5
Ym = -2.5
Midpoint = (-1.5, -2.5)

All the angles around a point on one side of a line add up to 180°.
A). Look at the angles at point-D, above the line.
You've got 40° and you've got a right angle ... 90°.
Those two angles add up to (40° + 90°) = 130°.
How much more is needed to make 180° ?
(180° - 130°) = 50°. That's angle 'x'.
B). Look at the angles at point-C, below the line.
You've got 55°.
How much more is needed to make 180° ?
(180° - 55°) = 125°. That's angle 'y'.
m∠x = 50°
m∠y = 125°
m∠x + 40° = 90°
x + 40 = 90
- 40 - 40
x = 50°
m∠y + 55° = 180°
y + 55 = 180
- 55 - 55
y = 125°
