Hello,

Rational numbers are numbers that can be represented by fractions that consist of integers.

In this case, B. -7/3 is already a fraction that consists of integers, so it is a rational number.
C. square 3 is = 3^{2} = 9, which can be represented by 9/1, so it is also a rational number.

A and D are incorrect as they cannot be represented by fractions that consist of integers.

The answers are B and C.

Hope this helps!

Answer:

A. 2.77777...

B. -\frac{7}{3}

Step-by-step explanation:

A rational number can be written in the form \frac{a}{b},where b\ne 0 and a,b are integers.

The number 2.77777... can be rewritten as \frac{25}{9}.

This is a rational number.

-\frac{7}{3} is also a rational number.

\sqrt{3}=1.73205080...

No recurring pattern so it is an irrational number

2.7182818459.... also has no recurring pattern. This is also an irrational number.

andreev551 [17]

Answer: h(g(x))= 2/6x-7

Step-by-step explanation:

1.h(g(x))= 2/(g(x))+3

2.g(x)= 3x-5

h(g(x))= 2/2(3x-5)+3

=2/6x-10+3

=2/6x-7

Find the points of intersection of the lines 10x−4y=2 and 2x+8y=7 without graphing.
Jet001 [13]

Answer:

x=\frac{1}{2},y=\frac{3}{4}

Step-by-step explanation:

Given:

10x-4y=2 ,2x+8y=7

To find: points of intersection of the given lines

Solution:

In substitution method, the system of equations is solved by expressing one variable in terms of another, as a result, removing one variable from an equation.

10x-4y=2 \\2(5x-2y)=2\\5x-2y=1\\5x=1+2y\\x=\frac{1+2y}{5}

Put x=\frac{1+2y}{5} in the equation 2x+8y=7

2x+8y=7\\2[\frac{1+2y}{5}]+8y=7\\ 2+4y+40y=35\\44y=35-2\\44y=33\\y=\frac{33}{44}\\ =\frac{3}{4}

Put y=\frac{3}{4} in the equation x=\frac{1+2y}{5}

x=\frac{1+2y}{5}\\=\frac{1}{5}[1+2(\frac{3}{4})]\\=\frac{1}{5}[1+(\frac{3}{2})]\\\\=\frac{1}{5}(\frac{2+3}{2}) \\\\=\frac{1}{5}(\frac{5}{2})\\\\=\frac{1}{2}

Therefore,

x=\frac{1}{2},y=\frac{3}{4}

What is 1/8 divided by 5/7
SpyIntel [72]
It becomes 7/40. To get it, you have to put 1/8 times 5/7. Then, flip the second fraction, (5/7), so that it becomes 7/5. Multiply 1/8 and 7/5, to get 7/40. You call this "reciprocal".
