What is Prime Factorization?

Prime factorization is the method of writing a number as the product of the prime factors.

For example 8 can be written as 8 = 2 × 2 × 2

The expression in the left is a multiplied form and that on the right is the prime factorized form.

1) 30abc

30 = 2 × 15 = 2 × 3 × 5

30abc = 2 × 3 × 5 × a × b × c

2) 45abr

45 = 3 × 15 = 3 × 3 × 5

45abr = 3 × 3 × 5 × a × b × r

3) 25ab

25 = 5 × 5

25ab = 5 × 5 × a × b

4) 2rs

2rs = 2 × r × s

5) 18rst

18 = 2 × 9 = 2 × 3 × 3

18rst = 2 × 3 × 3 × r × s × t

Hence the matching expressions are found.

On a certain hot​ summer's day, 399 people used the public swimming pool. The daily prices are $1.25 for children and $2.50 for adults. The receipts for admission totaled $601.25. How many children and how many adults swam at the public pool that​ day?

Answers

Answer:

children: 317

adults: 82

Step-by-step explanation:

x = children

y = adults

x + y = 399

125x + 250y = 60125

125x + 125y = 49875

125x + 250y = 60125

-125y = -10250

y = 82

x + y = 399

x + 82 = 399

x = 317

Answer:

82 adults   317 children  

Step-by-step explanation:

c= children

a = adults

A)     a+ c = 399

B)     1.25(c) + 2.50(a)  = 601.25

Multiply the whole  A)   by -1.25

Add     A) +B)    (c will be eliminated since 1.25c -1.25c=0)

-1.25 c - 1.25a  =  -498.74

1.25 c+ 2.50 a  =   601.25

            1.25 a  =  102.50

Divide both sides by 1.25:

                      a =  82    (82 adults)

         399-82 = 317  (317 children)

317 ($1.25) = $396.25  Price for 317 children

82($2.50) = $205    Price for 82 adults

Total:

   $ 396.25 + $205 =  $ 601.25

     317 + 82 = 399

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

We can use the slope-intercept form of a linear equation to find the

the y-intercept of the line.

The slope-intercept form of a linear equation is:

y = mx + b

where m is the slope of the line, and b is the y-intercept.

We are given the slope of the line that contains the points (1, -1) and

(2, 3) is 4.

Therefore, we can substitute m = 4 and one of the points into the equation, and solve for b.

Let's use the point (1, -1):

y = mx + b

-1 = 4(1) + b

-1 = 4 + b

b = -1 - 4

b = -5

The y-intercept of the line is -5.

The equation of the line in slope-intercept form is:

y = 4x - 5

Thus,

The y-intercept of the line is -5.
