Answer:
<em>45 </em>
Step-by-step explanation:
PQ = 45 units
Answer:
C
Step-by-step explanation:
both 4 and -4 are the same distance from 0
Answer:
a) - 11x - 94y / 12 b) x -4 / 5- 3x c) 12x - 11 /10y
Step-by-step explanation:
a) 2x - 6y / 4 - 4y - x/ 12 - 4x - 20y /3
6x - 18y / 12 - 4y - x / 12 - 16x - 80y / 12
= 5x - 14y / 12 - 16x - 80y / 12
- 11x - 94y / 12
b) x /5 - 4/ 3x = x -4 / 5- 3x
c) 2x -3/ 5y - 5- 2x / 10y + x/y
4x - 6 /10y - 5-2x/ 10y + 10x / 10y
2x - 11 / 10 + 10x / 10y
= 12x - 11 /10y
First multiply all terms by z
8-z^2=4z
Then order into standard form
-z^2-4z+8=0
Multiply the equation by -1
z^2+4z-8=0
Plug into quadratic equation
-4±√16-4(-8)
-4±√48
(-4±4√3)/2
-2±2√3
Final answer: z=-2± 2√3
Answer: No solution
<u>Step-by-step explanation:</u>
x - 3y = 2 → x = 3y + 2
2x - 6y = 6
2(3y + 2) - 6y = 6 <em>substituted x with 3y+2</em>
6y + 4 - 6y = 6 <em>distributed 2 into 3y+2</em>
4 = 6 <em>simplified (6y - 6y = 0)</em>
4 = 6 is a FALSE statement so there is NO SOLUTION
