The answer is 5x (combine like terms) also remember x=1 so it actually 2x - 1x +4x, hope that helps :)
<span>y=+- square root 5 over 3
y^2 + x^2 = 1 => x^2 = 1 - y^2 = 1 - 5/9 = 4/9 => x = +/- 2/3
Answer: x = +/- 2/3
y=+- square root 7 over 3
y^2 + x^2 = 1 => x^2 = 1 - y^2 = 1 - 7/9 = 2/9 => x = +/- (√2) / 3
Answer: x = +/-(√2)/3
y=+- 3 over 3
x^2 = 1 - y^2 = 1 - 3/9 = 1 - 1/3 = 2/3 => x = +/-(√2/3)
Answer: x = +/-√(2/3)
y=+- 2 square root 2 over 2
= y = +/- 2(√2) /2 = √2 ...... these y-coordinates are out of the unit circle, then there is not a corresponding x - coordinate for them.

Simple.
Just multiply .003 by 10.
0.003 x 10 = 0.00030, or 0.0003.
0.0003 is 1/10 of 0.003
Answer:
The expression is:
y=500x+550p, where
y is the amount earned
x is the quantity of Xboxes sold
p is the amount of Playstations sold
Step-by-step explanation:
With the information provided, you can say that the amount of money they will earn for selling Playstations and Xboxes is equal to the sum of the result of multiplying the price per Xbox Series X for the quantity sold plus the result of multiplying the price per Playstation 5 for the quantity sold, which can be expressed as:
y=500x+550p, where
y is the amount earned
x is the quantity of Xboxes sold
p is the amount of Playstations sold
