The absolute value of a number is the distance from 0 to that number. The distance is positive, hence, the absolute value is always a positive number.
ExerciseReplace the value of x:
[tex]| x - 8 |[/tex]
[tex]| -4 - 8 |[/tex]
[tex]| -12 | = \large{\boxed{12}}[/tex]
The absolute value of a number is the numerical value of the number, without regard to its sign.

m∠Q=
Answer:
105
Step-by-step explanation:
all of the angles added will add up to equal 180 so we setup the equation
180=11x-5+6x+5+x and solve
step 1 combine like terms
180=18x
step 2
divide each side by 18
x=10
then we just plug in 10 to 11x-5
11x10=110-5=105
angle q=105

At the Football game they expect that for every 4 people that attend 3 hot dogs will be sold. What is the equation
Answer:
If [tex]p[/tex] is people and [tex]h[/tex] is hot dogs, the equation is [tex]3h=4p[/tex].
The relation among people who attend and hot dog sold is 4x = 3y.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
At the Football game they expect that for every 4 people that attend 3 hot dogs will be sold.
let the are total x people and y number of hot dogs will be sold.
So, the relation among people who attend and hot dog sold is
4x = 3y

Shaggy earned 7.50 an hour plus an additional $100 in tips waiting tables last night. He earned more than $160 in all. Write an inequality to represent this situation and help you find the number of hours (h) he worked.
Answer
x>21.2
Step-by-step explanation:
7.55x+100>160:
subtract 100 on both sides to get:
7.55x>60:
divide 7.55 on both sides:
x>21.2 is your answer
Answer:
7.50h + 100 > 160
Step-by-step explanation:
7.50 is the hourly wage
h = hours he worked
add 100 once because it's his tips for the amount of time her worked
since he worked more than 160, you'll use the greater sign
then solve for h
h = 8 hours
Determine which function(s) are exponential. Select all that apply.
Answer:
option B and option C represent an exponential function.
Step-by-step explanation:
We know that following are some of the properties of different functions.
Linear Function:
The constant change in x and y
Quadratic Function:
The constant change in x
The constant 2nd differences in y
Exponential Function:
The constant change in x
The constant ratio in y
Determining the nature of the exponential function
Option A)
x 0 1 2 3 4
y 0 1 4 9 16
Here:
There is a constant change in x:
1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1
BUT, there is NO CONSTANT ratio, as
1/0 = ∞, 4/1 = 4, 9/4 ; 16/9
Thus,
Table A DOES NOT represents an exponential function.
Option B)
x 0 1 2 3 4
y 1/3 1 3 9 27
Here:
There is a constant change in x:
1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1
There is also a constant ratio, as
1/[1/3] = 3, 3/1 = 3, 9/3 = 3; 27/9 = 3
As there is constant change in x as well a constant ratio.
Thus,
Table B REPRESENTS an exponential function.
Option C)
x 0 1 2 3 4
y 5 5/2 5/4 5/8 5/16
Here:
There is a constant change in x:
1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1
There is also a constant ratio, as
[5/2]/5= 1/2,
[5/4]/[5/2] = 1/2
[5/8]/[5/4] = 1/2
[5/16]/[5/8] = 1/2
As there is constant change in x as well a constant ratio.
Thus,
Table C REPRESENTS an exponential function.
Option D)
x 0 1 2 3 4
y 4.5 4 3.5 3 2.5
Here:
There is a constant change in x:
1 - 0 = 1; 2 - 1 = 1; 3 - 2 = 1; 4 - 3 = 1
BUT, there is NO CONSTANT ratio, as
4/4.5 = 4/[45/10] = 40/45 = 8/9
3.5/4 = [35/10]/4 = 35/40 = 7/8
3/3.5 = 3/[35/10] = 30/35 = 6/7
2.5/3 = [25/10]/3 = 25/30 = 5/6
Table D DOES NOT represent an exponential function.
Conclusion:
Therefore, option B and option C represent an exponential function.
The functions that are exponential would be:
B). [tex]x[/tex] 0 1 2 3 4
[tex]y[/tex] 1/3 1 3 9 27
C). [tex]x[/tex] 0 1 2 3 4
[tex]y[/tex] 5 5/2 5/4 5/8 5/16
What are Exponential Functions?
B). Given that,
[tex]x[/tex] 0 1 2 3 4
[tex]y[/tex] 1/3 1 3 9 27
As we see,
The value of [tex]x[/tex] undergoes a constant change of 1
[tex]1 - 0 = 1; \\2 - 1 = 1; \\3 - 2 = 1; \\4 - 3 = 1[/tex]
The ratio also remains constant
[tex]1/[1/3] = 3, \\3/1 = 3, \\9/3 = 3; \\27/9 = 3[/tex]
Thus, it exemplifies an exponential function.
Similarly,
C). [tex]x[/tex] 0 1 2 3 4
[tex]y[/tex] 5 5/2 5/4 5/8 5/16
As we see,
The value of [tex]x[/tex] undergoes a constant change of 1
[tex]1 - 0 = 1; \\2 - 1 = 1; \\3 - 2 = 1; \\4 - 3 = 1[/tex]
The ratio also remains constant
[tex][5/2]/5= 1/2\\\\[5/4]/[5/2] = 1/2\\\\[5/8]/[5/4] = 1/2\\\\[5/16]/[5/8] = 1/2[/tex]
Thus, it exemplifies an exponential function.
Thus, options B and C are the correct answers as the other two have a constant change but not a constant ratio.

Javier earns $198 for 24 hours of work. (TRUE OR FALSE?)
Javier only needs to work one more hour to have enough money for his trip. (TRUE OR FALSE?)
Answer:
Becca's solution included all of the hours Javier worked on both weekends.Step-by-step explanation:
Javier needs to work at least 6 more hours. He will earn:
6*8 = $48He has already got:
$190 - $48 = $142He worked:
142/8 = 18 hours (rounded)Total he will have worked:
18 + 6 = 24 hoursAnswer choices:
Becca's solution included all of the hours Javier worked on both weekends.
TRUEJavier worked a total of 23 hours on both weekends.
FALSE. 23*$8 = $184 < $190Javier earns $198 for 24 hours of work.
FALSE. 24*8 = $192Javier only needs to work one more hour to have enough money for his trip.
