Rational numbers are those numbers that are integers and can be expressed in the form of x/y where both numerator and denominator are integers whereas irrational numbers are those numbers which cannot be expressed in a fraction. ... The denominator of a rational number is a natural number(a non-zero number).

Rational numbers and irrational numbers are mutually exclusive: they have no numbers in common. Furthermore, they span the entire set of real numbers; that is, if you add the set of rational numbers to the set of irrational numbers, you get the entire set of real numbers.

Answer: If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.

Solve the equations by elimination.<br> -7x-8y=9<br> -4x+9y=-22
Sergeeva-Olga [200]

Solve for x in -7x - 8y = 9

x = -9 + 8y/7

Substitute x = -9 + 8y/7 into -4x + 9y = -22

4(9 + 8y)/7 + 9y = -22

Solve for y in 4(9 + 8y)/7 + 9y = -22

y = -2

Substitute y = -2 into x = -9 + 8y/7

x = 1

Thus,

<u>x = 1</u>

<u>y = -2</u>

Can some help me with this problem
nasty-shy [4]

Answer:

The range is \{-9,-8,-7,-6,-5\}

The graph in the attached figure

Step-by-step explanation:

we have

y=x-7

The domain is the interval \{-2,-1,0,1,2\} ----> given problem

Remember that

The domain of a function is the set of all possible values of x

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

To find out the range of the function , find the value of y for each value of x

so

For x=-2 ----> y=-2-7=-9

For x=-1 ----> y=-1-7=-8

For x=0 ----> y=0-7=-7

For x=1 ----> y=1-7=-6

For x=2 ----> y=2-7=-5

therefore

The range is \{-9,-8,-7,-6,-5\}
