stepladder [879]

Answer:

The Video recorders are inferior goods.

Step-by-step explanation:

As Q_{v} =134-1.07Pf+46Pm-2.1Pv-5I

where;

The price of the recorders films are increasing by a term 1.07 which gives that the Price is increasing by a little. Also adding the Price of video recorder is increasing by a factor 2.1 and the Revenue or income is increasing by a term 5 (Which is high) so, revenue and price are increasing leaving the quality of the voice recorder decreasing by a large margin for maintaining the balance.

Completely simplify the expression 4x+10+6x+2x4x+10+6x+2x
oksian1 [2.3K]
<span>Simplifying 4x + 20 = 6x + -10 Reorder the terms: 20 + 4x = 6x + -10 Reorder the terms: 20 + 4x = -10 + 6x Solving 20 + 4x = -10 + 6x Move all terms containing x to the left, all other terms to the right. Add '-6x' to each side of the equation. 20 + 4x + -6x = -10 + 6x + -6x Combine like terms: 4x + -6x = -2x 20 + -2x = -10 + 6x + -6x Combine like terms: 6x + -6x = 0 20 + -2x = -10 + 0 20 + -2x = -10 Add '-20' to each side of the equation. 20 + -20 + -2x = -10 + -20 Combine like terms: 20 + -20 = 0 0 + -2x = -10 + -20 -2x = -10 + -20 Combine like terms: -10 + -20 = -30 -2x = -30 Divide each side by '-2'. x = 15 Simplifying x = 15</span>

2x^2 / x^2 - y^2 - x^2 / xy - y ^ 2​
Juliette [100K]

Answer:

2 - 2y^2 - x/y

Step-by-step explanation:

2x^2/x^2 = 2

and

x^2/xy = x/y

therefore

2x^2/x^2 - y^2 - x^2/xy - y^2

= 2 - y^2 - x/y - y^2

= 2 - y^2 - y^2 - x/y

= 2 - 2y^2 - x/y
