Which equation represents a line which is parallel to the line
y = −3/5x − 7?
-
3x + 5y = 15
5x + 3y = 12
3y - 5x = 6
3x - 5y = -30
Submit Answer
Answer:
3x+5y=15
Step-by-step explanation:
3x+5y=15
5y=-3x-15
y=-3/5x-3
Because it has the same slope and a different y-intercept, it is parallel because the lines won't ever touch.
Select all of the following tables which represent y as a function of x
.
The ordered pairs that represents a function y in terms of x are {(-2, -3),(1, 3),(1, 6) (9, 8}, (12, 11)) and {(-3, -5), (3, 2), (6, 5), (7, 9), (10, 16)}
Linear functionsA set of ordered equation represents a linear function if the domain of the coordinates are not repeated.
For instance, the ordered pairs that is a function are the coordinates that do not have any repeated y-coordinates.
From the given linear functions, the ordered pairs that represents a function y in terms of x are {(-2, -3),(1, 3),(1, 6) (9, 8}, (12, 11)) and {(-3, -5), (3, 2), (6, 5), (7, 9), (10, 16)}

3x+3=2(x+7)
What does x equal?
Answer: x = 11
Step-by-step explanation:
To solve we will isolate the variable, x.
Given:
3x+3=2(x+7)
Distribute:
3x+3=2x+14
Subtract 3 and 2x from both sides of the equation:
x = 11
what is 6x+2y=18 in intercept form?
Answer:
y = -3x + 9
Step-by-step explanation:
6x + 2y = 18
move 6x to the right of the equation by subtracting on both sides
2y = -6x + 18
then to single out the 'y' divide by 2 on both sides
y = -3x = 9

Hans deposits $6000 into an account that pays simple interest at a rate of 5% per year. How much interest will he be paid in the first 4 years?
Answer:
Hans deposits $6000 into an account.
=> Principal P = 6000
Simple interest rate 5% per year.
=> Rate R = 5% = 5/100 = 0.05
The formula to calculate the amount of interest after 4 years:
A = P x R x years = 6000 x (5/100) x 4 = 1200$

The table represents a linear function. What is the slope of the function?
-2 8

2 -16
The answer is -6., is the slope of the function.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
In order to determine the slope of the function, we have to know about linear function.
In any linear function, we can get its slope using two pairs of coordinates that belong to the linear function.
m=Slope of the linear function.
P1=(x1,y1)=First pair of coordinate.
P2=(x2,y2)=Second pair of coordinate.
In this case, we have many pairs of coordinates, so we choose two of them:
P_1=(-2,8)
P_2=(0,-4)
Then, we replace them in the slope formula:
m = y2-y1/x2-x1
= -6
Finally, the slope of the function is -6.

The percentage decrease is 43.75%
How to calculate the percentage?Initial volume = 3.2 millimeters
After experiment volume = 1.8 millimeters
Reduction = 3.2 - 1.8 = 1.4 millimeters
Therefore the percentage decrease will be:
= Reduction/Initial value × 100
= 1.4/3.2 × 100

what is the property of 3x(5x7)=(3x5)7
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

The total cost of the ticket with the discount and service fee is $214.33.
What is a percentage?A percentage is a ratio or number that may be expressed as a fraction of 100. Moreover, it is denoted by the sign "%."
Given:
The cost of a ticket on an airline is $220.
And Jameson receives a discount of 10%.
To find the discounted price:
The discounted price = 220 - 220 x 10 / 100
The discounted price = $198.
And the service charge is 8.25%.
So, the amount of service charge,
= 198 x 8.25/100
= 16.33
The total cost of a ticket = $198 + $16.33 = $214.33
Therefore, the cost is $214.33.

Answer:
The second box plot represents the data
Step-by-step explanation:
A box and whisker plot gives you the five-number summary of the data, which includes:
the minimum (lowest value of the data)
the maximum (highest value of the data)
Q1 (25% of the data lies below this point)
Q3 (75% of the data lies below this point), and
the median (the middle of the data).
The two ticks at the far left and far right of the box-and-whisker plot are the minimum and maximum respectively. From the data, we see that the minimum is 5 and the maximum is 10.
Although both plots have a minimum value of 5, only the second plot has the accurate maximum at 10.
The table below shows the lengths and weights of six dolphins at an aquarium. Use the data from Pax and Snowflake to create a linear model that predicts the weight (y) of a dolphin given its length (x). Which dolphin's weight differs most from the value predicted by this model?
The dolphin's weight that differs most from the value predicted by this model is JoJo's (31 lb of difference)
Let's elaborate the model this way:
Snowflake's length - Pax's length = 8.2 - 7.6 = 0.6 ft
Snowflake's weight - Pax's weight = 549 - 519 = 30 lb
Ratio = 30/0.6 = 50 lb/ft
This means that for every foot of length, the dolphin has a variable weight of 50 lb.
However, if we multiply the ratio by the actual length of the two dolphins, we will have these results:
Snowflake = 50 × 8.2 = 410
Pax = 50× 7.6 = 380
Snowflake = Actual weight - Ratio× Length = 549 - 410 = 139
Pax = Actual weight - Ratio × Length = 519 - 380 = 139
The common difference is 139.
Therefore, the linear model that predicts the weight (y) of a dolphin given its length (X) is:
y = 139 + 50x
Now, let's use the linear equation or model to calculate the weight of the remaining four dolphins, as follows:
Blaze y = 139 + 50 × 6.8 = 479 ⇒ difference of 9 lb (488 - 479)
JoJo y = 139 + 50 × 5.8 = 429 ⇒ difference of 31 lb (460 - 429)
Corky y = 139 + 50 ×8.4 = 559 ⇒ difference of 2 lb (559 - 557)
Shadow y = 139 + 50 × 7.4 = 509 ⇒ difference of 8 lb (509 - 501)
Hence, the dolphin's weight that differs most from the value predicted by this model is JoJo's (31 lb of difference)

PLEASE HELP !
Someone has offered you a wager on the outcome of a die roll. You will pay him
$100 for each time the standard, six-sided die lands on one, and he will pay you $30 for each time the die lands on any other number. Without your awareness, he has loaded the die so that it has a 40% change to land on the number one, and besides
that an equal change to land on any of the values 2 through 6.
What is the expected value of one round of gambling in this scenario?
-$12
-$32
$2
-$22
You'll lose on average $22 per roll.
====================================================
Explanation:
Normally there is a 1/6 chance to land on any given side of a standard die, but your friend has loaded the die in a way to make it have a 40% chance to land on "1" and an equal chance to land on anything else. Since there's a 40% chance to land on "1", this leaves 100% - 40% = 60% for everything else.
Let's define two events
A = event of landing on "1".B = event of landing on anything else (2 through 6).So far we know that P(A) = 0.40 and P(B) = 0.60; I'm using the decimal form of each percentage.
The net value of event A, which I'll denote as V(A), is -100 since you pay $100 when event A occurs. So we'll write V(A) = -100. Also, we know that V(B) = 30 and this value is positive because you receive $30 if event B occurs.
To recap things so far, we have the following:
P(A) = 0.40P(B) = 0.60V(A) = -100V(B) = 30Multiply the corresponding probability and net value items together
P(A)*V(A) = 0.40*(-100) = -40P(B)*V(B) = 0.60*30 = 18Then add up those products:
-40+18 = -22
This is the expected value, and it represents the average amount of money you earn for each dice roll. So you'll lose on average about $22. Because the expected value is not zero, this means this game is not mathematically fair.
This does not mean that any single die roll you would lose $22; instead it means that if you played the game say 1000 or 10,000 times, then averaging out the wins and losses will get you close to a loss of $22.
