What is the standard form of 5x^2+5y^2-10x+20y-30=0

o-na [289]

$5x^2+5y^2-10x+20y-30=0$

We need to get the equation in square form

We apply completing the square method

$5x^2-10x+5y^2+20y-30=0$

Divide all the terms by 5

$x^2-2x+y^2+4y-6=0$

Group x terms and y terms separately

$(x^2-2x)+(y^2+4y)-6=0$

By completing the square method, we take half of coefficient of x and square it

$\frac{-2}{2} = -1$

square it $(-1)^2= 1$

Add 1 on both sides

$(x^2-2x+1)+(y^2+4y)-6=+1$

$\frac{4}{2} = 2$

square it $(2)^2= 4$

Add 4 on both sides

$(x^2-2x+1)+(y^2+4y+4)-6=0+1+4$

Add 6 on both sides

$(x^2-2x+1)+(y^2+4y+4)=6+1+4$

Now factor both parenthesis

$(x-1)^2+(y+2)^2=11$

The equation of the circle is $(x-1)^2+(y+2)^2=11$

Drag the tiles to the correct boxes to complete the pairs. Add each pair of monomials and match it to the correct sum. -15u3 + 5

Grace [21]

Consider the given monomials. Let us determine the sum of these monomials,

1. $-15u^3+5u^3$

= $-10u^3$

Therefore, the sum of the given monomials is $-10u^3$ .

2. $10u^3+(-5u^3)$

= $10u^3-5u^3$

= $5u^3$

Therefore, the sum of the given monomials is $5u^3$ .

3. $10u^3+5u^3$

= $15u^3$

Therefore, the sum of the given monomials is $15u^3$ .

4. $5u^3+(-10u^3)$

= $5u^3-10u^3$

= $-5u^3$

Therefore, the sum of the given monomials is $-5u^3$ .

The cost per student of a ski trip varies inversely as the number of students who attend. It will cost each student $250 if 24 s

mars1129 [50]

ANSWER

30 students

EXPLANATION

The cost per student varies inversely as the number of students.

Inverse proportion is written as:

$\begin{gathered} y\propto\frac{1}{x} \\ y=\frac{k}{x} \\ \text{where k = constant of proportionality} \end{gathered}$

Let the cost per student be y.

Let the number of students be x.

It will cost each student $250 if 24 students attend. This means that:

$\begin{gathered} 250=\frac{k}{24} \\ \Rightarrow k=250\cdot24 \\ k=6000 \end{gathered}$

If the cost is down to $200, it means that y is now $200.

That is:

$\begin{gathered} 200=\frac{6000}{x} \\ \Rightarrow x=\frac{6000}{200} \\ x=30\text{ students} \end{gathered}$

Therefore, 30 students could attend.
