|x-3|<2
|4x+1|>0
|x-1|<5
Ayudaaaaaaa pleaseeeee
Recuerda que
• |x| = x si x ≥ 0
• |x| = -x si x < 0
Necesitas considerar dos casos:
• si x - 3 ≥ 0,
|x - 3| < 1 ⇒ x - 3 < 1 ⇒ x < 4
• si x - 3 < 0,
|x - 3| < 1 ⇒ -(x - 3) = 3 - x < 1 ⇒ -x < -2 ⇒ x > 2
Entonces la solución consta de todos los números reales x tales que x > 2 y x < 4, o simplemente 2 < x < 4.
El método para resolver las otras desigualdades es el mismo.
|4x + 1| > 0 ⇒ 4x + 1 > 0 o -(4x + 1) > 0
… ⇒ 4x + 1 > 0 o -4x - 1 > 0
… ⇒ 4x > -1 o -4x > 1
… ⇒ x > -1/4 o x < -1/4
⇒ x ≠ -1/4
|x - 1| < 5 ⇒ x - 1 < 5 o -(x - 1) < 5
… ⇒ x - 1 < 5 o -x + 1 < 5
… ⇒ x < 6 o -x < 4
… ⇒ x < 6 o x > -4
⇒ -4 < x < 6

what is the equalivent decimal for 17/20
Answer:
0.85
Step-by-step explanation:
20•5=100
17•5=x
7•5=35
10•5=50
35+50=85
then put the decimal 2 spots to the left and you will get 0.85 or 85%
Hey there!
• In order to convert a fraction into a decimal you divide the numerator (the number at the TOP) from the denominator (the number at the BOTTOM)
17/20
= 17 ÷ 20
= 0.85
= 85%
The decimal that is equivalent to 17/20 is: 0.85
Answer: 0.85

For what value(s) of k will the relation not be a function? S={(2-|k+1|,4), (-6,7)}
A relation is the relationship between variables. When each input has one output, the relation is a function. When the value of k is 5 or 3, the relation will not be a function.
Given that:
[tex]S= \{(2-|k+1|,4), (-6,7)\}[/tex]
For S, not to be a function, 1 domain element must point to more than one range elements.
This means that:
[tex]2-|k+1| = 6[/tex]
Collect like terms
[tex]-|k+1| = 6 - 2[/tex]
[tex]-|k+1| = 4[/tex]
Multiply by -1
[tex]|k+1| = -4[/tex]
Remove absolute bracket
[tex]k+1 = -4\ or\ k+1 = 4[/tex]
Solve for k
[tex]k =-1 -4\ or\ k= -1+4[/tex]
[tex]k =-5\ or\ k= 3[/tex]
Hence, when k is 5 or 3, the relation will not be a function.

2) Jessica went to the mall. She paid $14.57 on shorts and $10.20 on pants
with two $20 bills. She went to 2 shops. How much money did Jessica get in change?
Answer:
15.23
Step-by-step explanation:
First, you add 14.57 with 10.20 which equals 24.77.
then you minus 24.77 from 40 which equals 15.23!
hope this helps you :D
Hello :D
To do this you need to do:
$20 x 2 = $40.00
$14.57 + $10.20 = $24.77
$40.00 - $24.77 = $15.23
The answer is $15.23. I hope this helps :)

296 divide by 0.08 whats the answer plz answer, and show me how you did it plz
Answer:
Step-by-step explanation:
Ok so u can’t divide a decimal with a whole number so u have to move the decimal poin from the 8 twice so it’s on the other side of the 8 and then there shouldn’t be any zeros before the 8 now divide 296 by 8 and instead of leaving the whole number like that u have to add the decimal point to it. So it should look like this 296.00 and then u can divide which is 3,700 hope this helped <3
Point slope form and standard form
The point slope form, , is useful in situations involving slope and the location of one or more points. The standard form, , is usually easier to use when we need to make algebraic calculations. When needs or knowledge change, we can convert an equation from one form into another.
