its 1200 i think i work it out but i could have done it wrong
If you take the square root of a number squared number then they cancel each other out and the number stays the same i.e. √[(4)^2] would equal 4.
In this problem the square root and numbered squared cancel out to leave the problem as -2a.
The solution of this problem is -2a
Equation 1) 4x + 2y = 8
Equation 2) 16x - y = 14
Multiply all of equation 2 by 2.
2) 2(16x - y = 14)
2) 32x - 2y = 28
1) 4x + 2y = 8
Add equations together.
36x = 36
Divide both sides by 36.
x = 1
Plug in 1 for x in the first equation.
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
Subtract 4 from both sides.
2y = 8 - 4
2y = 4
Divide both sides by 2.
y = 4/2
y = 2
So, x = 1, y = 2

Answer:
the additional characters will the factory creating per day is 105 characters
Step-by-step explanation:
The computation of the additional characters will the factory creating per day is shown below
= Number of character produced × (1 + increased percentage)
= 350 × (1 + 0.30)
= 350 × 1.30
= 455 characters
Now the additional characters would be
= 455 - 350
= 105 characters
hence, the additional characters will the factory creating per day is 105 characters
Answer:
y = -1/3
x = 0
Step-by-step explanation:
3x-6y = 2 then 3x = 2+6y, x=(2+6y)/3
4x+3y = -1
substitute for x
4(2/3+2y)-6y = 2
8/3+8y-6y = 2
reduce
2y = 2-8/3
2y = -2/3
divide both sides by 2
y = -1/3
4x+3(-1/3) = -1
4x = 0
x = 0
