9(x-5)=5+(9x+5x)
9x-45=5+14x
9x-14x=45+5
-5x=50
X=50/-5
X=-10

$\\ \sf\longmapsto 2x+y=2$

$\\ \sf\longmapsto 2x=2-y$

$\\ \sf\longmapsto x=\dfrac{2-y}{2}\dots(1)$

And

$\\ \sf\longmapsto x+1=y+2$

$\\ \sf\longmapsto x=y+2-1$

$\\ \sf\longmapsto x=y+1$

Put the value

$\\ \sf\longmapsto \dfrac{2-y}{2}=y+1$

$\\ \sf\longmapsto 2-y=2(y+1)$

$\\ \sf\longmapsto 2-y=2y+2$

$\\ \sf\longmapsto 2-2=2y+y$

$\\ \sf\longmapsto 3y=0$

$\\ \sf\longmapsto y=\dfrac{0}{3}$

$\\ \sf\longmapsto y=\infty$

Put in eq(1)

$\\ \sf\longmapsto x=\dfrac{2-y}{2}$

$\\ \sf\longmapsto x=\dfrac{2-\infty}{2}$

$\\ \sf\longmapsto x=\dfrac{2}{2}$

$\\ \sf\longmapsto x=1$

The solution is y = -5

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c = 0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Given data ,

Let the function be f ( x ) = y

And , y = x² + 2x - 8

So , f ( x ) = x² + 2x - 8

Substituting the value for x in the equation , we get

When x = -3

f ( -3 ) = ( -3 )² + 2( -3 ) - 8

= 9 - 6 - 8

= 9 - 14

f ( -3 ) = -5

When x = 1

f ( 1 ) = ( 1 )² + 2( 1 ) - 8

= 1 + 2 - 8

= 3 - 8

f ( 1 ) = -5

Hence , the value of y = -5

Answer:

$24=4k$

$k=6$

Step-by-step explanation:

For this exercise it is important to remember that "Times as great as" indicates multiplication.

Therefore, "4 times as great as" can be expressed as following:

$4k$

So, the statement "24 is 4 times as great as" indicates that 24 is equal to $4k$ .

Knowing this, you can write the following equation:

$24=4k$

In order to solve for "k", you can divide both sides of the equation by 4. Then, you get the following result:

$\frac{24}{4}=\frac{4k}{4}\\\\k=6$
