Choose the graph that represents the inequality |x + 1| + 2 < –1
Answer:
Its graph A on edge. Just took it!
Step-by-step explanation:
The graph that represents the inequality |x + 1| + 2 < –1 is at option 1. Since the equation has no solution (empty set), the graph does not get intersected.
What is the inequality equation?The inequality equation is the one that is true for some values of the variable. The inequalities may be greater than, less than, greater than or equal, or less than or equal.
Solving the given inequality:The given inequality equation is
|x + 1| + 2 < –1
⇒ |x + 1| +2 - 2 < –1 -2
⇒ |x + 1| < –3
So, (x+1) < -3 or (x+1) > -3
⇒ x < -4 or x > -4
This is not possible. So the solution set of the given inequality is empty.
So, the graph is shown for different expressions.
The expressions are considered as
f(x) = |x + 1| + 2 and y < -1
In option 1, the graph shows these two expressions. So, the correct representation for the given inequality is option 1.
Since there is no solution, they do not have any intersecting points in the graph.

Find the volume of a cylinder that has a radius of 7 and a height of 16.
To find the volume of a cylinder, start with the formula for the volume of a cylinder.
Volume = [tex]\pi[/tex][tex]r^{2}[/tex][tex]^{h}[/tex]
Notice that our cylinder has a radius of 7 and a height of 16. So we have
([tex]\pi[/tex]) (7)[tex]^{2}[/tex] (16)
Let's start by simplifying the exponents. [tex]7^{2}[/tex] ≈ 49
([tex]\pi[/tex]) (49) (16)
49 × 16 = 784[tex]\pi[/tex][tex]m^{3}[/tex]
We can add a unit so we have 784[tex]\pi[/tex][tex]m^{3}[/tex].

What is the rate of change of y=6x-10
slope =6, y-intercept =10
Answer:
The rate of change is 6
Step-by-step explanation:

Predict weather the product of 3 and 4/5 is greater than, less then, or equal to 3 explain
Answer: Less than
Without actually solving this, we can find that the product of 3 and 4/5 will be less than 3. The reason for this is because 4/5 < 1. If we simply would do 3 * 1 we would just get 3. But since we are multiplying it by a number smaller than 1, we will be getting a number less than 3.
Solving this:
4/5 = 0.8
3 * 0.8 = 2.4
Tickets to the Valentines dance cost three dollars per person or five dollars per couple if $475 with the tickets were sold at 180 people attended the dance how many couples were there
50 individuals bought single tickets and 65 couples bought couple tickets.
Let's define our variables first:
Let [tex]x[/tex] be the number of individuals who bought single tickets.
Let [tex]y[/tex] be the number of couples who bought couple tickets.
From the problem, we have two pieces of information:
The total number of people who attended the dance is 180.The total revenue from the tickets sold is $475.We can use these pieces of information to create the following system of equations:
[tex]x + 2y = 180[/tex]
[tex]3x + 5y = 475[/tex]
First, solve equation 1 for [tex]x[/tex]:
[tex]x = 180 - 2y[/tex]
Now, substitute this expression for [tex]x[/tex] in equation 2:
[tex]3(180 - 2y) + 5y = 475[/tex]
Simplify and solve for [tex]y[/tex]:
[tex]540 - 6y + 5y = 475[/tex]
[tex]540 - y = 475[/tex]
[tex]-y = 475 - 540[/tex]
[tex]-y = -65[/tex]
[tex]y = 65[/tex]
So there were 65 couples at the dance.
To find the number of individuals who bought single tickets, substitute [tex]y[/tex] back into the expression for [tex]x[/tex]:
[tex]x = 180 - 2(65)[/tex]
[tex]x = 180 - 130[/tex]
[tex]x = 50[/tex]

What percent of 20 is 40
Answer: " 200 % . "
___________________________________________________
" 20 " is: " 200 % " of: "40 ."
___________________________________________________
Step-by-step explanation:
___________________________________________________
(n/100) * 20 = 40 ; Solve for "n" ;
Note that: percent = per "100" ; thus "(n/100)" ;
Divide each side of the equation by: "20" :
(n/100) * 20 ÷ 20 = 40 ÷ 20 ;
to get:
(n/100) = 2 ;
Multiply each side of the equation by "100" ; to get rid of the "fraction" ;
and to isolate "n" on one side of the equation ;
and to solve for "n" ;
(n/100) * 100 = 2 * 100 ;
to get:
n = 200 ;
The answer is: 200 % .

There is 200% of number 20 is, 40
Since, A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
We can assume that,
x% of 20 is, 40
Hence, We can formulate;
⇒ x% of 20 = 40
Solve for x;
⇒ x/100 × 20 = 40
⇒ x / 5 = 40
⇒ x = 40 × 5
⇒ x = 200

Step-by-step explanation:
Its just the other persons longer answer but simplified I guess..
The table below represents the function F. The equation that represents this function is
The answer is:
C. [tex]F(x)=2^{x}-1[/tex]
Why?In order to find the correct option, we need to substitute/evaluate the given values of "x" into each function.
Substituting into the first equation, option A:
[tex]F(x)=3^{x} \\F(3)=3^{3}=27\\F(3)=3^{4}=81[/tex]
... and so.
We can see that the option A is not the correct option since the obtained values do not match with the given values.
Substituting into the second equation, option B:
[tex]F(x)=3x\\F(3)=3*3=9\\F(4)=3*4=12\\[/tex]
... and so.
We can see that the values obtained from the function do not match with the given values, so the option B is not correct.
Substituting into the third equation, option C:
[tex]F(x)=2^{x}-1\\F(3)=2^{3}-1=8-1=7\\F(4)=2^{4}-1=16-1=15\\F(5)=2^{5}-1=32-1=31\\F(7)=2^{7}-1=128-1=127\\F(8)=2^{8}-1=256-1=255\\[/tex]
So, since all the obtained values match with the given values, we can conclude that the correct option is the option C.

use the substitution method to solve the system of equations
2x + 3y = 13
x = 2
To solve the system of equations using the substitution method, substitute the value of x into the other equation and solve for y.
Explanation:To solve the system of equations using the substitution method, we first need to solve one of the equations for one variable and then substitute that expression into the other equation. In this case, the second equation is already solved for x, so we can substitute x = 2 into the first equation:
2(2) + 3y = 13
4 + 3y = 13
3y = 9
y = 3
Therefore, the solution to the system of equations is x = 2 and y = 3.

A fair number cube ,labeled with 1 through 6 is rolled four times .What is the probability of rolling a 6 all four times ?
Answer:
1/1296
Step-by-step explanation:
Assuming that the probability of rolling a number is the same (1/6), all we have to do it multiply 1/6 by 4 (the number of times you roll the dice).
So 1/6 * 1/6 * 1/6 * 1/6 is just 1/6^4 and 6^4 is 1296.
Therefore the probability of rolling a 6 4 times in a row is 1/1296.
