         Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

A) Let's solve for x. y^2-7=2xy

Step 1: Flip the equation.

2xy = y^2 - 7

Step 2: Divide both sides by 2y.

\frac{2xy}{2y} = \frac{y^2- 7}{2y}

x = \frac{y^2- 7}{2y}

Answer : x = \frac{y^2- 7}{2y}

~~~~~~~~~~~~~

B) Let's solve for y. 2x^2+3=xy

Step 1: Flip the equation.

xy = 2x^2 + 3

Step 2: Divide both sides by x.

xy = \frac{2x^2 + 3}{x}

y = \frac{2x^2 + 3}{x}

Answer : y = \frac{2x^2 + 3}{x}

A plane traveled 460 mph with the wind and 400 mph against the wind. Find the speed of the plane in still air and the speed of t
Fudgin [204]
Let's say the speed of the plane is "p", and the speed of the wind is "w".

when the plane goes with the wind, is not really going "p" mph fast, is really going "p + w" mph fast, because the wind is adding speed to it.

likewise when the plane is going against the wind, is also not going "p" fast is going "p - w" mph fast.  Therefore,

\bf \begin{cases}
p+w=460\implies \boxed{w}=460-p \\
p-w=400\\
----------\\
p-\left( \boxed{460 - p} \right)=400
\end{cases}
\\\\\\
2p-460=400\implies 2p=860\implies p=\cfrac{860}{2}\implies p=430

-7x + 4y =10<br><br> -5x + 3y = 8
Margaret [11]

Answer:

x = 2, y = 6

(2, 6)

Step-by-step explanation:

The system of equations is solved when we find the "x" and "y" pair that is true for both equations.

We can use elimination, which is when we eliminate one of the variables. This can be done when both equations have a variable that has the same number.

Make both equations have "12y". Multiply each term by the same number.

-7x + 4y =10   }x3 =>   -21x + 12y = 30

-5x + 3y = 8  }x4 =>   -20x + 12y = 32

Subtract the equations from each other to get rid of 12y.

.     -20x + 12y = 32

<u>-     -21x + 12y = 30</u>

.          1x + 0y = 2    0y is nothing and 1x is x.

.                    x = 2    We have solved for x.

Now solve for y.

Use one of the equations:

-5x + 3y = 8    Substitute x for 2

-5(2) + 3y = 8     Simplify

-10 + 3y = 8     Start isolating x. Add 10 to both sides

3y = 18    Divide both sides by 3

y = 6    Solved for y.

The system of equations intersect at (2, 6).

Put the following equation of a line into slope-intercept form, simplifying all
Kitty [74]

Answer:

4(3x+17)

Step-by-step explanation:

move the 96 to the other side and make it negative. then combine similar terms, and finally factor out 4

12x+164=96

12x+164-96

12x+68

4(3x+17)

y=4(3x+17)
