Answer:
Usually there are the variables x y z but it doesn't matter what they are.
Step-by-step explanation:
First choose your first variable to solve. Find x by putting all the numbers and variables to one side.
once you found x substitute the answer for x in all the equations. Next find y and substitute your answer in all the equations again.
Once you have solved 2 variables then you are able to solve z.

<em>EXPLANATION:</em>
Classification of numbers according to the Venn diagram:
<em>Rational numbers:</em>
These numbers are represented by a fraction a / b, where a and b are integers and also b is different from zero.
<em>Whole numbers</em><em>:</em>
An integer is a natural number that can be positive or negative.
<em>Natural numbers:</em>
Natural numbers are those that start at zero to infinity are clearly positive.
<em>Rational numbers:</em>
When taking the square root of 8, 36 and 4 the result is an exact value that is why they are considered as rational numbers.
<em>Irrational Numbers:</em>
When the root of a number is not exact but is expressed as an infinite decimal as in the case of the square root of 140 which is 11.83215956619; this is an irrational number, also this result cannot be expressed as a fraction.
Answer:
<em> y = 1/2 x</em>
Step-by-step explanation:
Given the table
X 2//4//8//10//16
Y 1//2//4//5//8
We are to find the equation that represent the table
Using the coordinates of x and y components from the table (2, 1) and (4, 2)
The standard expression for the equation is expressed as y = mx+c
m is the slope
c is the y-intercept
Get the slope;
m = y2-y1/x2-x1
m = 2-1/4-2
m = 1/2
Get the intercept c:
Substitute the point (2, 1) and the slope m = 1/2 into the expression y = mx+c
1 = 1/2(2) + c
1 = 1+c
c = 1-1
c = 0
Get the required equation
Recall that: y = mx+c
y = 1/2 x + 0
<em>y = 1/2 x</em>
<em>Hence the required equation is y = 1/2 x</em>
