Replace x any with their values:
3(-4) + 7(6) -12
Simplify:
-12 + 42 -12
Solve:
-12 + 42 -12 = 42
Answer:
Step-by-step explanation:
-5+8x-9=3(x+3)
8x-14=3x+9
8x-3x-14=9
5x-14=9
5x=9+14
5x=23
x=23/5
----------------------
-216-3x=-12+6x
-216-3x-6x=-12
-216-9x=-12
9x=-216-(-12)
9x=-216+12
9x=-204
x=-204/9
x=-68/3
------------------
6-213-2x=-413-x
-207-2x=-413-x
-207-2x-(-x)=-413
-207-2x+x=-413
-207-x=-413
x=-207-(-413)
x=-207+413
x=206
------------------------
-(4x+9)=2x-3(2x+3)
-4x-9=2x-6x-9
-4x-9=-4x-9
Infinitely many solutions.

<u>Step 1: Define</u>
<em>Identify</em>
Point (-3, 0)
Point (-3, 11)
<u>Step 2: Find slope </u><em><u>m</u></em>
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>
- Substitute in points [Slope Formula]:

- [Fraction] Subtract:

- [Fraction] Simplify: m = undefined
∴ We have a vertical line at x = -3.
Answer:
Perpendicular Bisector Equation: y = 12x - 9.500
Step-by-step explanation:
Let find out the midpoint for given coordinates as follows:
[(-5+7)/2, (3 +2)/2]
= (2/2, 5/2)
= (1,5/2)
The midpoint coordinates are (1,5/2) means (x1 , y2)
2. Find the slop of line for given coordinates as follows:
(2-3)/(7-(-5)
= -1/12
3. Find the negative reciprocal as follows
-1/12
= 12 (m)
4. Now find the perpendicular bisector equation as follows:
y – y1 = m ( x – x1)
y – 3 = 12 (x – (-5)
y = 12x - 9.5
Answer:

Factor and you get
