To find out how many inches were gained, solve it with the expression 8 - x.
<h3>
Answer: Q = 8</h3>
====================================================
Explanation:
The left hand side of the first equation is x-3y
The left hand side of the second equation is 2x-6y = 2(x-3y). Note how it's simply double of the first expression x-3y
If we multiply both sides of the first equation by 2, we get
x-3y = 4
2(x-3y) = 2*4
2x-6y = 8
Meaning that 2x-6y = 8 is equivalent to x-3y = 4. Both produce the same line leading to infinitely many solutions. Each solution will lay along the line x-3y = 4.
We can say each solution is in the set {(x,y): x-3y = 4}
Which is the same as saying each solution is of the form (3y+4,y)
To check for symmetry on the x axis, replace y with –y
-y^2 –x(-y) =2
<span> Apply the product
rule, since the equation is not identical tot eh original equation it is not
symmetric about the x axis</span>
<span> Now do the same for y
axis by replacing x with –x</span>
<span> Again using product
rule the equations are not identical, so it is not symmetric about the y axis</span>
<span> To check the origin,</span>
<span> Replace both x &
y with –x & -y</span>
Again using product rule, the equations are not identical so
it is not symmetric about the origin
62 +510 + 10 = 572
572 ÷ 2 = 286.
<span>y=-x^12 has the minimum value.</span>
