Answer:
k ≥ 1
Step-by-step explanation:
Step 1: Write inequality
4(k - 5) + 12k ≥ -4
Step 2: Solve for k
Distribute 4: 4k - 20 + 12k ≥ -4Combine like terms: 16k - 20 ≥ -4Add 20 to both sides: 16k ≥ 16Divide 16 on both sides: k ≥ 1HELPPPP!!!

Two straight roads meet at right angles at an intersection. A car is traveling due
south towards the intersection at a constant speed of 60 miles per hour. A second
car is traveling due west towards the same intersection at a constant speed of 70
miles per hour. How fast is the distance between the cars changing at the instant

Hence, Option C is correct!!~A ternary string is an ordered string of characters which consists of digits (0,1, or 2). For example, the ternary string 2122010 consists of exactly 2 zero's, 2 one's and 3 two's; another ternary string meeting these conditions is 0021221. How many ternary strings are there with exactly 4 zero's, 3 one's and 6 two's?
The number of ternary strings is an illustration of combination
There are 6227020800 ternary strings with exactly 4 zero's, 3 one's and 6 two's
How to determine the number of stringsAssume the zero's, one's and the two's can take any position in the string
For a ternary string of exactly 4 zero's, 3 one's and 6 two's, the number of characters in the string is 13.
The first 4 zeros can take any of the 13, 12, 11 and 10th positions
The next 3 ones can take any of the 9, 8 and 7th positions
The remaining 6 twos can take any 6! positions
So, the number of strings is:
Strings = 13* 12 * 11 * 10 * 9 * 8 * 7 * 6!
Evaluate the products
Strings = 6227020800
Hence, there are 6227020800 ternary strings with exactly 4 zero's, 3 one's and 6 two's

Answer:
i think it would be -14 + 2y so the mistake was making the 2y negative
Step-by-step explanation:
Negative times negative = positive
Answer: The distribution of -2(7 - y) is incorrect. They came out with -14 -2y.
It should have been -14 + 2y
At the end, it would have been a division by +2 , so the solution would be y=3

Answer:
Step-by-step explanation:
Part A
Area of a rectangle = length x width
Garden area = 7 3/4 x 2 2/3
= 31/4 x 8/3
= 62/3
= 20 2/3 square feet
Part B
5/8 of the area = 62/3 * 5/8
= 31*5 / 3*12
= 155 / 36
= 4 11/36
The question asks to do so without calculation - the only way is that because the length is approximately 8 feet, section off 5 feet along the length will give an area approximately 5/8 of the total area.

5. A group of eighth-graders at your school is thinking of forming a club whose members rent DVDs. The club would also rent DVDs to non-members but at a higher price. They decided to create a membership for $20 flat fee and then charge $4 per DVD for members. Non-members could also rent a DVD, but for $5 per DVD. When would the membership be worth the money?
The membership would be worth the money if the number of DVD's rented is more than 20
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the cost of renting x DVD
They decided to create a membership for $20 flat fee and then charge $4 per DVD for members. For members:
y = 4x + 20
Non-members could also rent a DVD, but for $5 per DVD
y = 5x
The membership would be worth the money if:
5x > 4x + 20
x > 20
The membership would be worth the money if the number of DVD's rented is more than 20

Determine whether the underlined number describes a population parameter or a sample statistic. Explain your reasoning. Sixty-five of the 93 passengers aboard an airship survived an explosion Choose the correct statement below.
A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.
B. The number is a population parameter because it is a numerical description of all of the passengers that survived.
C. The number is a population parameter because it describes the people in the airship, which is a subset of all people.
D. The number is a sample statistic because it describes the people in the airship, which is a subset of all people.
Answer: A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.
Step-by-step explanation:
A population is simply similar items or events that a researcher or an experimenter is interested and wants to carry out an experiment on.
A statistic is simply referred to as the piece of information gotten from the population while a sample statistic is the piece of statistical information which a researcher will be able to get from the statistic.
In this scenario, the number is a sample statistic because it is a numerical description of all of the passengers that survived.
Consider the line y=7/4x-4.
Find the equation of the line that is perpendicular to this line and passes through the point (8,2)
Find the equation of the line that is parallel to this line and passes through the point (8,2)
Answer:
[tex]\displaystyle \perp\:y = -\frac{4}{7}x + 6\frac{4}{7} \\ \parallel\:y = 1\frac{3}{4}x - 12[/tex]
Step-by-step explanation:
Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE RATE OF CHANGES [SLOPES], so 1¾ becomes −⁴⁄₇, and we move forward:
[tex]\displaystyle 2 = -\frac{4}{7}[8] + b \hookrightarrow 2 = -4\frac{4}{7} + b; 6\frac{4}{7} = b \\ \\ \boxed{y = -\frac{4}{7}x + 6\frac{4}{7}}[/tex]
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so 1¾ remains as is as we proceed:
[tex]\displaystyle 2 = 1\frac{3}{4}[8] + b \hookrightarrow 2 = 14 + b; -12 = b \\ \\ \boxed{y = 1\frac{3}{4}x - 12}[/tex]

(9) A software company estimates that if it assigns x programmers to work on the project, it can develop a new product in T days, where T= 100 – 30.x + 3x^2. How many programmers should the company assign in order to complete the development as quickly as possible?
Using the vertex of the quadratic equation, it is found that the company should assign 5 programmers in order to complete the development as quickly as possible.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the time needed for x programmers to finish the project is given by:
T(x) = 100 - 30x + 3x².
Which means that the coefficients are a = 3, b = -30, c = 100. The number of programmers which will minimize the time is given by:
[tex]x_v = -\frac{-30}{6} = 5[/tex]
