What is inequality?Inequality, is a declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
For the given graph the solution is the point where the shading intersect and the number in this area is 3
Therefore, we conclude that point 3 is the area for the actual solution of the inequality

How many solutions does the equation 3x-9=3(x-3) have ?
Answer:0
Step-by-step explanation:
3x^9=3(x-3
We move all terms to the left:
3x^9-(3(x-3)=0
Answer:
1 solution which is infinite solutions
Step-by-step explanation:
There is only one solution to this because if we simplify both sides of the equation, we get 3x-9=3x-9. When we add 9 to both sides we are left with 3x=3x and subtracting 3x from both sides will make the equation 0=0 which is infinite solutions. This is the only answer/solution we can get from this problem
Olivia typed 2 pages in 12 minutes. How long will it take her to type 10 pages at this rate?
Answer:
60
Step-by-step explanation:
If Olivia typed 2 pages in 12 minutes, this means that she can type 1 page in 6 minutes. Since we're looking for the amount of time it would take her to type 10 pages, we multiply 6 by 10 to get 60.
Answer:
60 minutes
Step-by-step explanation:
if Olivia writes 2 pages in 12 minutes that means she writes 1 page in 6 minutes. 6 minutes per page times 10 pages equals 60 minutes for 10 pages.
samantha needs to bake at least 120 pot pies to sell at her restaurant. she can bake 12 pot pies per hour and 15 veggie pot pies per hour.
write an inequality that represents the situation. let X be the number of hours she spends making chicken pot pies and y be the number of hours she spends making veggie pot pies.
Answer:
y>(line under >) - 4/5x + 8
Step-by-step explanation:
Phrase "at least" indicates that the total number of pies is greater than or equal to 120.
The number of chicken pot pies Samantha makes is 12x, and the number of veggie pot pies she makes is 15y.
Use this information to create the inequality:
12x + 15y >(line under >) 120
Simplify by solving for y to get this inequality:
y >(line under >) - 4/5x + 8

Which statement correctly describes the decimal form of: 2/9
Answer:
0.222 (repeated)
Step-by-step explanation:
Fractions are essentially another way to write a division expression.
This means that if a/b, then it can also be written as a÷b. (a and b are variables)
So, 2/9 is the same thing as 2÷9.
You can then calculate 2÷9 using a calculator, long division, or any other way you usually solve questions involving division.

Answer:
y= -1.4x-6.6
Step-by-step explanation:
(1,-8)
7x+5y=-7
Make the equation into standard form
Subtract 7x from both sides
5y=-7x-7
Divide all by 5
y=-1.4x-1.4
Since they are parrallel, we know the slope is -1.4x
y=-1.4x+b
(1,-8) is one of the points it goes through
Replace the x and y in the equation for the x and y in the incomplete equation
-8=-1.4+b
Add 1.4 to both sides
-6.6=b
Thus the equation is
y=-1.4x-6.6

There are 8 fewer than double the
number of students in the chorus than in
the band. There are 54 members in the
chorus. Which equation represents how
to find the number of students in the
band?
A. 2x - 8= 54
B. 2x + 8 = 54
C. 8x - 2 = 54
D. 8x + 2 = 54
Answer:
The equation to find the number of students in the
the band will be: 2x - 8= 54
Step-by-step explanation:
Let the number of members in the chorus = x
so the double number of members in the chorus will be = 2x
As Total members in the chorus = 54
As there are 8 fewer than double the number of students in the chorus than in the band. i.e. 2x - 8
Therefore, the equation to find the number of students in the
the band will be: 2x - 8= 54

A professor of statistics wants to test that the average amount of money a typical college student spends per day during spring break is over $70. Based upon previous research, the population standard deviation is estimated to be $17.32. The professor surveys 35 students and finds that the mean spending is $72.43. Which of the following statements is most accurate? Select one: a. reject the null hypothesis at ? = 0.01 b. reject the null hypothesis at ? = 0.10 c. fail to reject the null hypothesis at ? ? 0.10 d. reject the null hypothesis at ? = 0.05
Answer:
Option c: Fail to reject the null hypothesis at α = 0.10
Step-by-step explanation:
We are given;
Population mean; μ = 70
population standard deviation; σ = 17.32
Sample mean; x¯ = 72.43
Sample size; n = 35
Thus;
Null hypothesis; H0: μ = 70
Alternative hypothesis; Ha: μ > 70
Z-score formula is;
z = (x¯ - μ)/(σ/√n)
z = (72.43 - 70)/(17.32/√35)
z = 2.43/2.9276
z = 0.83
From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.05 and one tailed hypothesis, we have;
P-value ≈ 0.2033
It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.05
Similarly, From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.01 and one tailed hypothesis, we have;
P-value ≈ 0.2033
It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.01
Similarly, From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.10 and one tailed hypothesis, we have;
P-value ≈ 0.2033
It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.10
From the 3 significance values, the correct option is option c. fail to reject the null hypothesis at α = 0.10
Using the z-distribution, it is found that the most accurate statement is:
c. fail to reject the null hypothesis at [tex]\alpha = 0.1[/tex]At the null hypothesis, it is tested if the average spending is not over $70, that is:
[tex]H_0: \mu \leq 70[/tex]
At the alternative hypothesis, it is tested if it is over $70, that is:
[tex]H_1: \mu > 70[/tex].
We have the standard deviation for the population, hence, the z-distribution is used to solve this question.
The test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean. [tex]\mu[/tex] is the value tested at the null hypothesis. [tex]\sigma[/tex] is the standard deviation of the sample. n is the sample size.In this problem, the values of the parameters are as follows: [tex]\overline{x} = 72.43, \mu = 70, \sigma = 17.32, n = 35[/tex].
Hence, the value of the test statistic is:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{72.43 - 70}{\frac{17.32}{\sqrt{35}}}[/tex]
[tex]z = 0.83[/tex]
Using a significance level of [tex]\alpha = 0.1[/tex], the critical value for the right-tailed test, as we are testing if the mean is greater than a value, is [tex]z^{\ast} = 1.28[/tex].
The lower the significance level, the higher the critical value.Since for a significance level of 0.1, [tex]z < z^{\ast}[/tex], we fail to reject the null hypothesis at [tex]\alpha = 0.1[/tex], and option c is correct.
