Answer: y=2x-1
Step-by-step explanation:
Equation of a line that passes through (a,b) and have slope m is given by :-
[tex](y-b)=m(x-a)[/tex] [point slope form]
Given, Point = (4,7) , m= 2
Equation in point slope form : [tex](y-7)=2(x-4)[/tex]
To write in slope intercept form (y=mx+c) , we need to simplify it
[tex]y-7= 2x-8\\\\\Rightarrow\ y-2x=-8+7\\\\\Rightarrow\ y-2x=-1\\\\\Rightarrow\ y=2x-1[/tex]
Hence, y=2x-1

A company makes 100 bags. 32 of the bags have buttons but no zips. 32 of the bags have zips but no buttons. 35 of the bags have neither zips nor buttons. How many bags have zips on them?
Answer:
32.
Step-by-step explanation:
The first 32 have buttons but NO zips.
Then 35 have NEITHER buttons OR zips.
Then 32 have ZIPs, but no buttons.
The question only asks for zips. The other bag is unaccounted for.

The goals against average (A) for a professional hockey goalie is determined using the formula A = 60 a = 60 (g /t) .. In the formula, g represents the number of goals scored against the goalie and t represents the time played, in minutes.
Three friends went for dinner and ordered Pizza for $12, Salads for $6 and Drinks for $6. If they divide the total cost equally, how much did each friend pay?
Answer:
Step-by-step explanation:
Total = 12 + 6 + 6 = 24
Divided in 3 friends = 24 ÷ 3 = 8
Each should pay 8
How do you do this question?
Step-by-step explanation:
(a) dP/dt = kP (1 − P/L)
L is the carrying capacity (20 billion = 20,000 million).
Since P₀ is small compared to L, we can approximate the initial rate as:
(dP/dt)₀ ≈ kP₀
Using the maximum birth rate and death rate, the initial growth rate is 40 mil/year − 20 mil/year = 20 mil/year.
20 = k (6,100)
k = 1/305
dP/dt = 1/305 P (1 − (P/20,000))
(b) P(t) = 20,000 / (1 + Ce^(-t/305))
6,100 = 20,000 / (1 + C)
C = 2.279
P(t) = 20,000 / (1 + 2.279e^(-t/305))
P(10) = 20,000 / (1 + 2.279e^(-10/305))
P(10) = 6240 million
P(10) = 6.24 billion
This is less than the actual population of 6.9 billion.
(c) P(100) = 20,000 / (1 + 2.279e^(-100/305))
P(100) = 7570 million = 7.57 billion
P(600) = 20,000 / (1 + 2.279e^(-600/305))
P(600) = 15170 million = 15.17 billion

Answer:
The student scores 20 pts
Step-by-step explanation:
A student answers 10 Q's correct, this earns the student 30 points (3 x 10)
The other 5 Q's are presumably wrong since they did answer the question
If every question wrong loses 2 pts then the student lost 10 points from wrong answers (2x5) =10
Take the total amount of secured points and subtract the points for questions that the student got wrong
30 pts - 10 pts = 20 pts
Answer:
20
Step-by-step explanation:
15 questions answered
10 are correct so they get 30 or 3*10
5 are incorrect so the get a -10 or -2*5
Total score is 30-10 or 20

A company is interested in learning if employees are satisfied with their jobs. To find out the company hires an independent market research
company to conduct a survey. Every survey filled out by an employee is anonymous. Which of the following statements is correct?
A This method of sampling is biased.
B This method of sampling is unbiased.
C This method of sampling is neither biased nor unbiased. D This method of sampling can be considered both biased and unbiased.
The statement (B) is correct because it is anonymous, it does not focus on a specific ethnicity, gender, or other factor.
What is a survey?A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.
We have:
A company is interested in learning if employees are satisfied with their jobs.
Every survey that an employee fills out is completely anonymous.
The statement (B) this method of sampling is unbiased because it is anonymous, it does not focus on a specific ethnicity, gender, or other factor.
Thus, the statement (B) is correct because it is anonymous, it does not focus on a specific ethnicity, gender, or other factor.

solve the system of linear equations by substitution.
x + 4y = 6
x - y = 1
9514 1404 393
Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Use the second equation to write an expression for x:
x = 1 +y
Substitute that into the first equation:
(1 +y) +4y = 6
5y = 5 . . . . . . . . subtract 1, collect terms
y = 1 . . . . . . . divide by 5
x = 1 +1 = 2 . . . use the expression for x to find x from y
The solution is (x, y) = (2, 1).

11) Find the value for x for both diagrams please help me
Answer:
Step-by-step explanation:
11 a).
20x + 5 + 24x - 1 = 180
44x = 176
x = 176 / 44
x = 4
b). 6x = 5x + 10
x = 10
Look at the scatter plot. Which of these equations is the best representation of the trend line?
A. y = -5x + 5
B. y = 5x + 5
C. y = -5x - 5
D. y = 5x - 5
Solve for x:
5x - 15 = 2030
Answer:
x=409
Step-by-step explanation:
First add and make the varible on one side of the equation: add 15 to both sides. 5x=2045
Then divide to find x. 2045/5=409
A giant tortoise can travel 0.14 miles in 1 hours .At this rate ,how long would it take to travel 2 miles ?
Answer:
about 14.3 hours
Step-by-step explanation:
The relation between time, speed, and distance can be written any of three ways:
time = distance/speeddistance = speed×timespeed = distance/time__
Here, the question asks for the travel time, so the relevant relation is the first one. Filling in the given values, we have ...
time = (2 mi)/(0.14 mi/h) ≈ 14.29 h
It would take about 14.3 hours to travel 2 miles.
