|x-3| < 5 please help
ratelena [41]

Answer:

\left|x-3\right|

The graph is also attached.

Step-by-step explanation:

Given the expression

|x-3|\:

Apply absolute rule:

\mathrm{If}\:|u|\:0\:\mathrm{then}\:-a\:

so the expression becomes

-5

x-3>-5\quad \mathrm{and}\quad \:x-3

solving condition 1

x−3<5

Add 3 to both sides

x−3+3<5+3

x<8

solving condition 2

x−3>−5

Add 3 to both sides

x−3+3>−5+3

x>−2

combining the intervals

x>-2\quad \mathrm{and}\quad \:x

Merging overlapping intervals

-2

Therefore,

\left|x-3\right|

The graph is also attached.

Answer:

  see the attachment for a graph

  (x, y) = (0.5, 2.5)

Step-by-step explanation:

The first equation has a slope of 1 and a y-intercept of 2.

The second equation has a slope of -1 and a y-intercept of 3.

The two lines cross at the point (0.5, 2.5), which is the solution to the system of equations.

RATHER THAN USE DECIMALS-convert it to cents..
stepan [7]

Answer:

<h2>there are 22 dimes</h2><h2>there are 44 nickles</h2><h2 />

Step-by-step explanation:

D be dimes and N be nickles

2 nickles as dime

nickle = 5 cents and dime =10 cents

N=2D

0.10 D + 0.05 (N)=4.4 substitute N=2D

0.10 D +0.05(2D)=4.4

0.10D+0.10D=4.4

0.20 D=4.4

D=4.4/0.2 = 22

<h2>there are 22 dimes</h2>

N=2D

N=2(22)

N=44

<h2>there are 44 nickles</h2>

check : 0.10(22)+0.05(44)= 4.4 (correct)

AfilCa [17]
22 quarters= $5.50
10 dimes= $1.00

$5.50 + $1.00 = $6.50
I just did trial and error. I started with 20 quarters and made changes until it worked.

To which subset of real numbers does the number 1/5 belong?
nasty-shy [4]

Answer: Option 'B' and 'C' are correct.

Step-by-step explanation:

Since we know that irrational numbers are those real number which cannot be written in \frac{p}{q} form.

Rational numbers are those real numbers which can be written in \frac{p}{q} form.

Inverse property of multiplication is that property in which we write a number in reciprocal form .

Whole numbers starts from 0 and Natural numbers start from 1 and Integers contain both positive and negative numbers.

Hence, \frac{1}{5} belongs to rational numbers sets and inverse property of multiplication sets.

Therefore, Option 'B' and 'C' are correct.
