Does anyone know the answer to this , its math inequalities
48 > -6x
Answer:
[tex]x > - 8[/tex]
Step-by-step explanation:
Swap the sides of the inequality and flip the inequality sign:
[tex] - 6x < 48[/tex]
Divide both side of the inequality by -6 and flip the inequality sign:
[tex]x > - 8[/tex]
[tex]48 > - 6x \\ \\ \\ Change \: The \: Sides \\ Of \: Value \: With \: Signs \\ \\ \implies - 6x < 48 \\ \\ \implies \: x > - 8[/tex]

Show some work please
9514 1404 393
Answer:
B. 2 +3x
Step-by-step explanation:
The greatest common factor of 12 and 18 is 6:
12 = 6×2
18 = 6×3
The greatest common factor of x² and x is x². Factoring out the greatest common factors, we have ...
12x² +18x³ = 6x²(2 +3x)
The factors are 6x² or (2 +3x). The last of these is an answer choice.
2 +3x is a factor
how to go in minutes from hours and hours to minutes answer in picture welcome in advance
Answer:
trick:
1 hour = 60 minutes
ex if said to convert 25 minutes to hour so
1 hour/60=1minutes
multiply both sides with 25
25 x 1hour/60=25minutes
5/12 hours=25 minutes
just like that for hour
log(x)²=(logx)², find the value of x
Answer:
x = 7.39
Step-by-step explanation:
log(x)²=(logx)², find the value of x
log x² = log x * log x
2log x = log x * log x
2 = log x
Take the exponent pf both sides
e² = e^logx
e² = x
x = e²
x = 7.39
A researcher is going to estimate the average typing speed of students of a college. He selects a random sample of 20 students and finds the average typing speed of 70 wpm and the standard deviation of 5 wpm. Estimate the lower bound of the 80% confidence interval of the average typing speed of a student of this college. Express your answer using THREE decimal places
Answer:
The lower bound of the 80% confidence interval of the average typing speed of a student of this college is of 68.516 words per minute.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-interval is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 20 - 1 = 19
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.8}{2} = 0.9[/tex]. So we have T = 1.328
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.328\frac{5}{\sqrt{20}} = 1.484[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 70 - 1.484 = 68.516 wpm.
The lower bound of the 80% confidence interval of the average typing speed of a student of this college is of 68.516 words per minute.

In a lab experiment, 610 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 23 hours. How long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present?
Answer:
It would take 19 hours and 36 minutes until there are 1040 bacteria present.
Step-by-step explanation:
Given that in a lab experiment, 610 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 23 hours, to determine how long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present, the following calculation must be performed:
610X = 1040
X = 1040/610
X = 1.7049
2 = 23
1.7049 = X
1.7049 x 23/2 = X
39.2131 / 2 = X
19.6 = X
100 = 60
60 = X
60 x 60/100 = X
36 = X
Therefore, it would take 19 hours and 36 minutes until there are 1040 bacteria present.

If the graph of f(x) = |x| is shifted up 5 units, what would be the equation of the new graph?
A. g(x) = |x + 5|
B. g(x) = |x| + 5
C. g(x) = |x| - 5
D. g(x) = |x - 5|
Answer:
B. g(x)= |x| + 5
Step-by-step explanation:
-5 represents a vertical shift down, so that narrows it down to either A or B. A shows a shift across the horizontal (X) axis, so it must be B.

A sofa is on sale for $258.40 which is 34%of the regular price. What was the regular price?
Answer:
$760
Step-by-step explanation:
Set up an equation:
Variable x = regular price
34/100 = 258.40/x
Cross multiply
34 × x = 100 × 258.40
34x = 25,840
Divide both sides by 34
x = 760
Check your work:
760 × 34%
Convert the percentage into a decimal:
760 × 0.34
$258.40

The function f(x) = 4x ^ 2 + 2x represents the revenue a company earns x years after 2000, and g(x) = 10x + 125 represents the cost per year. Write a function P(x) for the profit the company earns per year. (Hint: Profit is the difference of revenue and cost.)
Answer:
Tamil Tamil Tamil Tamil Tamil
The function P(x) for the profit the company earns per year is P(x) = 4x^2 - 8x + 125
How to calculate the profit functionFrom the given information, we have the following
revenue function f(x) = 4x^2 + 2x
Cost per year C(x) = 10x+ 125
The profit = Revenue - Cost
P(x) = 4x^2 + 2x - 10x+ 125
P(x) = 4x^2 - 8x + 125
Hence function P(x) for the profit the company earns per year is P(x) = 4x^2 - 8x + 125

Answer:
1. nonsense
2. x = 1, y = 2, z = -1, w = -2
Step-by-step explanation:
1. Matrices are added term by corresponding term. Consider the upper left term in each matrix. The equation says 4 + 3 = 8. This is nonsense, so we cannot figure what you expect to solve.
__
2. This resolves to 4 equations:
3y = 6 ⇒ y = 23z = -3 ⇒ z = -12y+4x = 8 ⇒ 4+4x = 8 ⇒ x = 12z = w ⇒ -2 = wThe solutions are ...
(w, x, y, z) = (-2, 1, 2, -1)
