Answer:

1, 3, and 4 would be correct answers

Step-by-step explanation:

1.) -x - 2x - 3y - 2y + 1 + 1 = -3x -5y + 2

2.) -3x + 2y + 3y + 2 = -3x + 5y + 2

3.) -3x - y - y - y - y - y + 2 = -3x - 5y + 2

4.) -x - x - x - y - y - y - y - y + 1 + 1 = -3x - 5y + 2

5.) x + x + x + y + y + y + y + y + 1 + 1 = 3x + 5y + 2

Hope this helps!

What's the property to (x/y)^3=x^3/y^3

Sphinxa [80]

Answer:

Power of a quotient property

Step-by-step explanation:

It is power of a quotient property, when you have different bases, whose quotient(division) is raised to the same power, it is equal to dividing, each base raised to same power.

Here, x and y are different bases and 3 is the common power to both of them.

In general for any power, say m :

$(\frac{x}{y} )^{m} = \frac{x^{m} }{y^{m}}$

Because, $(\frac{x}{y} )^{m} = \frac{x}{y} \times \frac{x}{y} \times\frac{x}{y}.... m times$

And, $(\frac{x}{y} )^{3} = \frac{x}{y} \times \frac{x}{y} \times\frac{x}{y}$

i.e $(\frac{x}{y} )^{3} = \frac{x^{3} }{y^{3}}$

Which of the following are possible discriminants for a quadratic function that crosses the x-axis twice? Check all that apply.

Sedaia [141]

Answer:

1001

Step-by-step explanation:

If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in $ax^2+bx+c$ with discriminant $b^2-4ac$ , the following is true:

If $b^2-4ac>0$ , then the quadratic has two real solutions
If $b^2-4ac=0$ , then the quadratic has one real solution
If $b^2-4ac$ , then the quadratic has no real solutions

Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.
