what is the domain of the function f(x)=6x+3
Answers
Answer:
All Real Numbers
Step-by-step explanation:
This is a linear function, so the domain is All Real Numbers, or (-∞, ∞). In other words, the all numbers on the x-axis are defined on the graph. We have no points where x is undefined or imaginary. Domain contains all real numbers.

Based on the graph below, how would you describe the curve?
A. The curve is a linear function
B. The curve is a "many-to-one" function.
C. The curve is a "one-to-one" function.
D. The curve is not a function.
Answers
Based on the curve ; The graph is:
B. The curve is a many-to-one function.
Step-by-step explanation:Function--
A function is a relation in which each element is mapped to a single element i.e. no element is mapped to two different elements.
Also, the graph of a function satisfies the vertical line test i.e. any line passing through the domain and parallel to the y-axis should intersect the graph exactly once.
and one-to-one function--
A one-to-one function is such that no two elements have the same image i.e. any line passing through the co-domain and parallel to the x-axis should intersect the graph at most once.
The graph passes the vertical line test and hence is a function.Also, the graph of a linear function is a straight line.Hence, by looking at the graph we see that the graph is not a straight line.
Hence, it is not a linear function.
Also, it does not passes the horizontal line test (since somewhere in the interval (2,3) the same value is obtained many times )and hence it is not a one-to-one functionHence, the correct answer is:

Identify the algebraic description that maps a point (3, 7) onto another point (-5, 7).
A) (x,y) → (x-8, y)
B) (x,y) → (x, y - 8)
C) (x, y) → (x, y + 8)
D) (x,y) → (x+8, y)
Answers
Answer:
A) (x, y) → (x - 8, y)
Step-by-step explanation:
(3, 7) → (-5, 7)
Without adding or subtracting any values, we can immediately tell that the y-value did not change, but the x-value did. With this, we are left with choices A and D.
A) (x, y) → (x - 8, y)
(3, 7) → (3 - 8, y)
(3, 7) → (-5, 7)
This matches our problem, and therefore, A is the correct answer.
Hope this helps!
Answer:
A) (x, y) → (x-8, y)
Explanation:
Present Point: (3, 7)
Future Point: (-5, 7)
The change be: (x, y)
Solve:
(3, 7) + (x, y) → (-5, 7)
change side
(x, y) → (-5, 7) - (3, 7)
simplify the following
(x, y) → (-8, 0)
Therefore, we identify this using (x - 8, y)

The amount of time a certain brand of light bulb lasts is normally distributed with a
mean of 1400 hours and a standard deviation of 50 hours. Using the empirical rule,
determine what interval of hours represents the lifespan of the middle 68% of light
bulbs.
Answers
The interval of hours represents the lifespan of the middle 68% of light bulbs, using the empirical rule is, 1210 hours to 1390 hours.
What is empirical rule?According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.
[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]
Here, we had where mean of distribution of X is \mu and standard deviation from mean of distribution of X is \sigma
The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1400 hours and a standard deviation of 50 hours. Thus,
[tex]\mu=1300\\\sigma=90[/tex]
Using the empirical rule, the interval of hours represents the lifespan of the middle 68% of light bulbs is,
[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(1300- 90 < X < 1300+ 90) = 68\%\\P(1210 < X < 1390) = 68\%[/tex]
Thus, the interval of hours represents the lifespan of the middle 68% of light bulbs, using the empirical rule is, 1210 hours to 1390 hours.

A sporting goods company near the beach rents bicycles for $10 plus &5 per hour. Write an equation in
slope-intercept form that shows the total cost, y, of renting a bicycle for x hours. How much would it cost
Emily to rent a bicycle for 6 hours?
Answers
Answer:
It will cost Emily $40 to rent the bike for 6 hours.
Step-by-step explanation:
SOLUTION:
Total cost equals = (cost per hour × number of hours) + initial bike cost.
Let, y be total cost and x = renting a bicycle for x hours.
y=5x+10
To calculate Emily's cost for 6 hours, let x=6.
y=5(6)+10
y=30+10
y=40
It will cost Emily $40 to rent the bike for 6 hours.

Answers
Answer:20%
Step-by-step explanation:
Solution for 600 is what percent of 3000:
600:3000*100 =
( 600*100):3000 =
60000:3000 = 20
Now we have: 600 is what percent of 3000 = 20
Question: 600 is what percent of 3000?
Percentage solution with steps:
Step 1: We make the assumption that 3000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that $100%=3000.
Step 4: In the same vein, x%=600.
Step 5: This gives us a pair of simple equations:
$100%=3000(1).
x%=600(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% / %=3000/600
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100%=600/3000
--->=20%
Therefore, $600 is $20% of $3000.
2.7% of X equals 50,000. what is X?
don't give fake answers just for points YOU WILL BE REPORTED
Answers
Answer:
x = 1851851.851....
Step-by-step explanation:
Given statement:
2.7% of x equals 50,000.
When we convert the statement into an equation, we get;
⇒ 2.7% × x = 50,000
A percentage is always written as (Percent)/100 in fraction form. Thus;
⇒ 2.7/100 × x = 50,000
Using cross multiplication:
⇒ 2.7 × x = 50,000 × 100⇒ 2.7 × x = 5,000,000To determine the value of x, we need to isolate it. This can be done by dividing the cooeficient of x both sides.
Divide both sides by 2.7
⇒ (2.7 × x)/2.7 = 5,000,000/2.7⇒ x = 1851851.851....Answer:
Percent in decimal form:
[tex]\sf 2.7\% = \dfrac{2.7}{100} = 0.027[/tex]
Therefore:
27% of X = 50000
[tex]\sf \implies 0.027 \cdot X=50000[/tex]
[tex]\sf \implies X=\dfrac{50000}{0.027}[/tex]
[tex]\sf \implies X=\dfrac{50000 \times 1000}{0.027 \times 1000}[/tex]
[tex]\sf \implies X=\dfrac{50,000,000}{27}\quad \textsf{(as a fraction)}[/tex]
[tex]\sf \implies X=1,851,852\quad \textsf{(nearest whole number)}[/tex]
