Answer:

x=4 and y=5

Step-by-step explanation:

Find x by adding the two equations so that the 6y and -6y will cancel out.

You're left with 6x=24 which you divide 6 on both sides to get x=4.

Then to find y you will plug 4 into either equation for x. I chose the second equation, so 4-6y=-26, get -6y alone by subtracting the 4 over to the other side. then -6y=-30, then divide both sides by -6 and you get y=5.

Answer:

see below

Step-by-step explanation:

y = 8x − 9

y = 4x − 1

Since both equations are equal to y, we can set them equal to each other

8x-9 = 4x-1

Subtract 4x from each side

8x-4x-9 = 4x-4x-1

4x-9 = -1

Add 9 to each side

4x-9+9 = -1+9

4x = 8

Divide each side by 4

4x/4 = 8/4

x=2

Now find y

y = 4x-1

y = 4(2)-1

y = 8-1

y = 7

Find the real and/or imaginary solutions by factoring

SIZIF [17.4K]

Answer:

Step-by-step explanation:

1) (x-3),(x-8)

2) 3x^3+3x^2=27x

3 ( x 3^3+ x ^2 − 9 x − 9 )

3 ( x ^2 ( x + 1 ) − 9 ( x + 1 ) )

3 ( ( x + 1)( x ^2 − 9 ) )

3 ( ( x + 1 ) ( x ^2 − 3 ^2 ) )

3 ( x + 1 ) ( x + 3 ) ( x − 3 )

Use the inverse of the function y = x2 − 18x to find the unknown values.

Lerok [7]

ANSWER

b=1, c=81, and d=9.

EXPLANATION

The given function is:

$y={x}^{2}-18x$

This function is the same as:

$y={(x - 9)}^{2}-81$

To find the inverse of this function, we interchange x and y.

$x={(y-9)}^{2}-81$

Solve for y:

$x+81={(y- 9)}^{2}$

Take square root of both sides:

$\pm \sqrt{x + 81}=y-9$

$y=\pm \sqrt{x + 81}+9$

Hence,

b=1, c=81, and d=9.
