The solution has to be a value of x. Since you already have x, you just have to plug in the value and see what fits. In this case thats the third from the top:

5^2 - 10*5 + 25 = 0

25 - 50 + 25 = 0

0 = 0

Hope it helps!

Solve by the substitution method.
GalinKa [24]

Answer:

The unique solution to the system is (x,y){(-9,-3)}

Step-by-step explanation:

x - y = -6     equation 1

5x + 6y = -63     equation 2

We will find the value of x from equation 1.

x= y-6

Now put the value of x in equation 2.

5(y-6)+6y = -63

5y-30+6y = -63

Combine the like terms:

5y+6y= -63+30

11y = -33

Divide both sides by 11.

11y/11 = -33/11

y = -3

Now put the value y = -3 in x=y-6

x = y-6

x= -3-6

x= -9

Therefore The unique solution to the system is (x,y){(-9,-3)} ....

What is the volume of a cylinder with the base radius of 10 units and a height of nine units?
Otrada [13]

Answer:

V = 2827.43\ units^3  or V = 900\pi\ units^3

Step-by-step explanation:

The volume of a cylinder is calculated by the following formula

V = \pi r^2 *h

Where r is the radius of the cylinder and h is the height

In this case we know that the radius r of the base is:

r=10\ units

and

h=9\ units

So the Volume is:

V = \pi (10)^2 *9

V = 900\pi\ units^3

V = 2827.43\ units^3

julsineya [31]

Answer:

The chi-square null hypothesis for the study that "socioeconomic status is related to smoking behavior" is False
