solve the inequality for x. 5 is greater than or equal to 4x+9 . simplify as much as possible
Answers
Answer:
X ≤ - 1
Step-by-step explanation:
5 ≥ 4x + 9 ( subtract 9 from both sides )
- 4 ≥ 4x ( divide both sides by 4 )
- 1 ≥ x , then
x ≤ - 1

help with horizontal asymptotes
Answers
Answer:
y = 3. last option is correct answer for 2nd question.
Step-by-step explanation:
f(x) just means y.
horizontal asymptote is y = 'something.'
the graph crosses y = 4, so y = 4 cannot be asymptote.
y = 3 is since the graph never quite touches it.
as for ∞, we see that as x approaches -∞, y almost reaches 3. but not quite. also, as x approaches +∞, y approaches +∞.
so the last option is the correct answer.

Answers
Alonzo has $3.00 in dimes and nickels. The number of dimes he has is twice the number of nickels
that he has. How many dimes does he have?
Answers
Answer:
30 dimes
Step-by-step explanation:
Since a dime is equal to .10 and each nickel is worth .05, and there is double the amount of dimes then we can conclude that if we had 1 collection of all then we would have 2 dimes and a nickel, or .25. So now we divide 3.00 by 0.25 and get 12, now since there is 2 dimes in per 1 nickel we multiply this by 2 and get 24.

Signature of the Principle investigator on the final proposal implies his responsibility for the following except
Answers
The signature of the Principal Investigator on the final proposal does not imply responsibility for the availability of funding or the financial aspects of the project.
The signature of the Principal Investigator (PI) on the final proposal does not imply responsibility for certain aspects of the project beyond their control or expertise. While the PI plays a crucial role in leading and overseeing the research project, there are certain areas for which they may not bear direct responsibility.One aspect the PI may not be responsible for is the availability of funding. Although they may have been involved in securing the initial funding or writing the budget proposal, the final decision and availability of funds typically lie with funding agencies, institutions, or sponsors. The PI's signature on the proposal signifies their commitment to the project but does not guarantee funding.Additionally, the PI may not be accountable for the technical or scientific success of every aspect of the project. Research projects often involve interdisciplinary collaborations and multiple team members who contribute their expertise. The PI's signature signifies their leadership and overall responsibility, but they rely on the expertise and contributions of other team members for specific tasks and outcomes.Furthermore, the PI may not bear sole responsibility for external factors that can impact the project, such as changes in regulations, unforeseen events, or external market conditions. While they may adapt the project's direction and approach as needed, these external factors are beyond their direct control.In summary, the signature of the Principal Investigator on the final proposal does not imply responsibility for funding availability, technical success of every aspect, or external factors that may influence the project. The PI's role is primarily centered around leadership, coordination, and overall project management.The complete question should be What does the signature of the Principal Investigator on the final proposal NOT imply responsibility for?

Write these numbers in order from least to greatest. (You will have to change the fractions to equivalent decimals to place them in the correct order.). 0.131,0.141,0.121,0.139,0.1201,0.1401,0.14,0.147,0.149,0.137
Answers
Answer:
0.1201<0.121<0.131<0.137<0.139<0.14<0.1401<0.141<0.147<0.149
Step-by-step explanation:
OK let's see the numbers:
0.131,0.141,0.121,0.139,0.1201,0.1401,0.14,0.147,0.149,0.137
First off, we find the smallest number, We highlight the ones that have 1 for hundredth digit, looks like there's none!, try 2 for the hundredth digit:
0.131,0.141,0.121,0.139,0.1201,0.1401,0.14,0.147,0.149,0.137
There's two! 0.1201 is smaller than 0.121, so 0.1201 one is smallest followed by 0.121.
What we already have:
0.1201<0.121
Then we find the decimals that have 3 for hundredth digit.
0.131,0.141,0.121,0.139,0.1201,0.1401,0.14,0.147,0.149,0.137
There's three!
0.131 is smaller than 0.137 and both of them are smaller than 0.139.
What we already have:
0.1201<0.121<0.131<0.137<0.139
We now find the decimals that have 4 for hundredth digit.
0.131,0.141,0.121,0.139,0.1201,0.1401,0.14,0.147,0.149,0.137
There's five!
We can see that 0.14 is smaller than 0.1401 is smaller than 0.141 is smaller than 0.147 is smaller than 0.149.
What we already have:
0.1201<0.121<0.131<0.137<0.139<0.14<0.1401<0.141<0.147<0.149
And this is the answer:
0.1201<0.121<0.131<0.137<0.139<0.14<0.1401<0.141<0.147<0.149

Answers
Step-by-step explanation:
In order to test the rate of growth of the functions, we use a single value of x to monitor the results of all the equation.
Let's use a random value of 3;
The equation with the highest result is the one that grows the quickest
a. (x) = 5x + 3
a. (x) = 5(3) + 3 = 18
b. (x) = 3x + 5
b. (x) = 3(3) + 5 = 14
c. (x) = x +4
c. (x) = (3) +4 = 7
d. (x) = 1 + 4x
d. (x) = 1 + 4(3) = 1 + 12 = 13
Upon going through the results and arranging in increasing order;
c. (x) = x +4
d. (x) = 1 + 4x
b. (x) = 3x + 5

Answer and Step-by-step explanation:
I will replicate what you said into an algebraic equation.
Your number will be represented as x.
(3x + 3) - (2x + 1) = 9
Distribute the negative.
3x + 3 - 2x - 1 = 9
Combine like terms.
x + 2 = 9
Subtract both sides of the equation by 2.
x = 7
Your number is 7.
Checking my answer:

13 A young girl standing on a cliff is throwing stones up into the air so that they land in the ocean below. The height h, in meters, of each stone above the ocean is related to the
time 1, in seconds, after it has been thrown by the function
h = -21? + 21 + 40. What is the maximum height reached by
each stone?
Answers
The maximum height reached by each stone is 40.5 meters.
The height of each stone above the ocean is given by the function:
h = -2t² + 2t + 40
This is a quadratic function in standard form, with a = -2, b = 2, and c = 40.
The maximum height reached by the stone occurs at the vertex of the parabolic curve described by this function.
The t-coordinate of the vertex is given as:
t = -b / 2a
Substitute the values of a and b,
t = -2 / (2×(-2)) = 0.5
So the maximum height is reached 0.5 seconds after the stone is thrown.
To find the maximum height, substitute the value of t into the function:
h = -2(0.5)² + 2(0.5) + 40 = 40.5 meters
Therefore, the maximum height reached by each stone is 40.5 meters.

Answer:

Step-by-step explanation:
I had originally put B, but my teacher explained and said its C.
the first part of b is correct where it says 8/5, bc you need to flip it in order to not have a negative exponent (you cant have a negative exponent as an answer) but 0.42 is correct and iit does not need to be fliped, since there is no (8/5)(0.42)^2 option, you need to make the 8/5 into a decimal, it becomes 1.6 and so the answer is C
A system of equations is given.
Equation 1: 4x − 6y = 10
Equation 2: 9x + 2y = 7
Explain how to eliminate x in the system of equations.
Answers
Step-by-step explanation:
To eliminate x in the system of equations:
1. Multiply Equation 1 by 9 and multiply Equation 2 by -4, this gives:
Equation 1: 36x -54y = 90
Equation 2: -36x - 8y = -28
2. Add the two equations together to eliminate x:
(36x - 54y) + (-36x - 8y) = 90 - 28
Simplifying, we get:
-62y = 62
3. Solve for y:
y = -1
4. Substitute y = -1 into one of the original equations, say Equation 1:
4x - 6(-1) = 10
Simplifying, we get:
4x + 6 = 10
5. Solve for x:
4x = 4
x = 1
Therefore, the solution to the system of equations is x = 1 and y = -1. We can check that these values are correct by substituting them back into the original equations and verifying that they satisfy both equations.

The equations x² + 4x + 3 = 0 and x² -6x + 13 = 0 are equivalent to (x + 2)² = 1 and (x - 3)² = -4
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on
The standard equation of a quadratic function is:
y = ax² + bx + c
1) Given that:
x² + 4x + 3 = 0
subtract 3 from both sides:
x² + 4x = -3
add to both sides the square of half the coefficient of x:
x² + 4x + 4 = -3 + 4
(x + 2)² = 1
2) Given that:
x² - 6x + 13 = 0
subtract 13 from both sides:
x² - 6x = -13
add to both sides the square of half the coefficient of x:
x² - 6x + 9 = -13 + 9
(x - 3)² = -4
The equations are (x + 2)² = 1 and (x - 3)² = -4
