Answer: The second description is correct for the absolute value of x
Main details: Horizontal line from 0 to the dot 6 ticks to the left, and 6 written above the line
Step-by-step explanation: breaking it down:
A number line is shown from negative 6 to positive 6 with increments of 1. All the numbers are labeled on the number line. The first part is the same in all of the descriptions
A dot is shown on a point at 6 tick marks to the left of 0. This represents -6 on the number line.
Above the number line, a bracket is shown extending from a point at 6 tick marks to the left of zero to 0. This shows the distance between 0 and -6. Important. Absolute value is the distance between two numbers
A horizontal line is shown between the brackets, This is the measuring line 6 units long.
and 6 is written on the line. Important. It is a plain number, no negative or positive! Absolute value is just that.
Refer to the figure.

Step-by-step explanation:
find the value of (x-6)/3 if x =21
Greetings.
The answer is 5.
Explanation:
[tex]\frac{x-6}{3}[/tex]
We want to know the value when x = 21. Therefore, substitute x = 21 in the expression.
[tex]\frac{21-6}{3}[/tex]
Evaluate 21-6 = 15
[tex]\frac{15}{3}[/tex]
Therefore, the answer is 5.

Step-by-step explanation:
Which statement best illustrates using the vertical line test to determine if the graph below is a function of x? On a coordinate plane, a circle is centered around (0, 0). The graph is not a function of x because the line x = 0 intersects the graph at two points. The graph is a function of x because the line x = 5 does not intersect the graph. The graph is not a function of x because the line y = 0 intersects the graph at two points. The graph is a function of x because the line y = 5 does not intersect the graph.

Answer:
37.5
Step-by-step explanation:
14/2=7.5 . Use 7x5=35. 5x0.5=2.5
Answer: $37.50 because you first divide 5 by 2, then you multiply by 15, then you get 37.5
Is this a function
Yes or no
Answer:
yes.
Step-by-step explanation:
by performing the vertical line test, you can see that the line only goes through one point, so it is a function.
Answer:
yes
Step-by-step explanation:
it passes the vertical line test (you could draw a vertical line anywhere on the graph, and it wouldn't pass through the graph more than once.

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 1 and the Trailing Constant is -9.
The factor(s) are:
of the Leading Coefficient : 1
of the Trailing Constant : 1 ,3 ,9

A survey of 1000 Californians finds reports that 48% are excited by the opportunity to take a statistics class.
The margin of error in this report is 5%. Which answer choice best describes a reasonable range of values for the percent of
students who are excited to take a statistics class?
Answer:
(0.449, 0.511) is the range for the percent of students who are excited to take a statistics class
Step-by-step explanation:
First of all, let's check that the sample size is large enough to use normal approximation.
Conditions are;
np > 10
n(1-p) > 10
Now, we have;
n = 1000
p = 48% = 0.48
Thus;
np = 1000 × 0.48 = 480 > 10
Also;
n(1 - p) = 1000 × (1 - 0.48) = 520 > 10. This means the conditions for normal approximation have been fulfilled. Hence we can use the confidence interval formula to get the range of values which is;
CI = p ± z√(pq/n)
We are given a margin of error and thus the confidence interval is at 95%.
Critical value of z at 95% CI is 1.96
Thus;
CI = 0.48 ± 1.96√(0.48 × 0.52/1000)
CI = 0.48 ± 0.031
CI = (0.449, 0.511) is the range for the percent of students who are excited to take a statistics class
For your birthday, you want to take a group of friends to an indoor trampoline
center. There are two trampoline parks available on your date. You only have
$250 to spend on your party.
Pricing Information:
Sky High: $50 for a party set up fee and $5 per person after that. Write an inequality model for both trampoline parks.
Jump it Up: $70 for a party set up fee and $2 per person.
In jump it up you can bring 90 friends.
In Sky high, you can bring 40 friends.
Answer:
Skyhigh : 40 friends
Jump it up : 90 friends
Step-by-step explanation:
Given that :
Total amount available to spend = $250
JUMP IT UP:
Party set up fee = $70
Amount paid per person = $2
Number of friends = 90
SKY HIGH:
Party set up fee = $50
Amount paid per person = $5
Number of friends = 40
INEQUALITY :
Party setup fee + amount per person * Number of persons ≤ available amount to spend
SKY HIGH:
50 + 5x ≤ 250
5x ≤ 250 - 50
5x ≤ 200
x ≤ 200/5
x ≤ 40
Hence,
Skyhigh = 90 friends
JUMP IT UP:
70 + 2x ≤ 250
2x ≤ 250 - 70
2x ≤ 180
x ≤ 180/2
x ≤ 90
Jump it up = 90

You can solve the following proportion by cross multiplying. What will the equation be after you cross multiply?
3 x= 9 • 15
3 x = 15
3 • 15 = 9 X
15 = 9 X
=====================================
Explanation:
Anything in the form A/B = C/D will cross multiply to A*D = B*C
In this case, A = 3, B = 9, C = x and D = 15
So that's why 3/9 = x/15 cross multiplies to 3*15 = 9*x

on what interval is the function h(f)=|x+2|-2 increasing ?
Answer:
The increasing interval is [tex]S=(-2,\infty)[/tex]
Step-by-step explanation:
This absolute function has a vertex in x=-2. Now, from this point, the function has a positive slope (increasing), which means for values of x equals to -1,0,1,2,3,...,n.
Therefore the interval will
[tex]S=(-2,\infty)[/tex]
