Answer:

y = 1/2x + 2

Step-by-step explanation:

Find your y-intercept (0,2) then a random point (-2,1). Then count the distance from the two points, 1 up & 2 right.

1/2 is now your slope!

y = 1/2x + 2

What does the symbol zero or o with a diagonal line through it mean?
Anit [1.1K]
In mathematics, an empty set is a unique set having no elements inside it. Its size (which is based on the number of elements inside it) is also zero.

The empty set is sometimes called a null set as well.

Empty set is given the notation of o with a diagonal line through it as shown in the attached picture.

Express the given percent as a decimal.1/2% (Round to five decimal places as needed.)
grin007 [14]

Answer:

The required expression is \frac{1}{2}\%=0.00500

Step-by-step explanation:

Given : Percentage \frac{1}{2}\%

To find : Express the given percent as a decimal ?

Solution :

To convert percentage into decimal,

To remove percentage sign we divide the given number by 100.

So, \frac{1}{2}\%=0.5\%

Remove percentage,

\frac{1}{2}\%=\frac{0.5}{100}

Now, Put decimal after three digit

\frac{1}{2}\%=0.005

As we have to round it to five decimal places,

\frac{1}{2}\%=0.00500

Therefore, The required expression is \frac{1}{2}\%=0.00500

Solve the system using substitution.
Maru [420]

Answer:

Given: The following system:

4x + y − 2z=18          ......[1]

2x-3y+3z = 21          ......[2]

x-3y=6                      ......[3]

we can write equation [3] as;

3y = x-6                     ......[4]

Multiply by 3 in equation [1] to both sides of an equation we get,

3 \cdot(4x+y-2z)= 3\cdot 18 or

12x+3y-6z=54              ......[5]

Substituting the equation [4] in [2] and [5] we get;

2x-(x-6)+3z=21 or

2x-x+6+3z=21

Simplify:

x+3z=15            .....[6]                       [combine like terms]

12x+x-6-6z =54

Simplify:

13x-6z=60         ......[7]        [Combine like terms]

On Solving equation [6] and [7] simultaneously,

x+3z=15

13x-6z=60

we get the value of x

i.e, x=6

Substitute the value of x in equation x+3z=15  we get

6+3z=15 or

3z=9

Simplify:

z=3

Also, substitute the value of x=6 in equation [3] we get the value of y;

x-3y=6

6-3y=6 or

-3y = 0

Simplify:

y = 0

Therefore, the solution to the system of three linear equation is, (6, 0 , 3)
