y - 35 = 2(x - 10)
Step-by-step explanation:
Let
y-----> the height of the plant
x ----> the number of days
Find the slope
we have the points
(10,35)
The slope is equal to
m= (55-35)/(20-10)
m= 2
Find the equation of the line into point slope form
y- y1 = m(x - x1)
we have
m= 2 and point (10,35)
y - 35 = 2(x - 10)

If every 4 cm on a scale drawing is equal to 3 yards in rea
scaled-drawing lengths below would be less than 9 yards in real life? Select all that apply. A) 16 cm B) 6 cm C) 8 cm D) 24 cm
The scale drawing which is equal to 9 yards in real time is 12 cm.
Given that 4cm on the scale, drawing is equal to 3 yards in real-time
we have to find the scale drawing which is equal to 9 yards in real-time.
Let the scale drawing be 'x'
Now it can be written as
4 cm ------ 3 yards
x cm ------- 9 yards
Now we can divide this as
4/x = 3/9
By cross multiplication, we get
4 * 9 = 3 * x
x = 4 * 9 / 3
x = 12
Therefore, the scale drawing which is equal to 9 yards in real time is 12 cm.

Step-by-step explanation:
Let's solve your equation step-by-step.
5/9 = x/54
Step 1: Cross-multiply.
5/9 = x/54
(5)*(54)=x*(9)
270=9x
Step 2: Flip the equation.
9x=270
Step 3: Divide both sides by 9.
9x/9 = 270/9

Question
Consider the following two loans for Po = $15,000.
• Loan A: 5 year loan, annual interest rate of 8%, monthly repayments of $304.15.
Loan B: 3 year loan, annual interest rate of 11%, monthly repayments of $491.08.
Calculate the absolute difference between the total interest paid on both loans. Give your answer to the nearest ten dollars.
Do not include the dollar sign in your answer
Answer:
570
Step-by-step explanation:
570
The absolute difference that is between the loans paid as 570
How to solve for the absolute differenceWe have the following details:
Po = $15000
loan a 5 year loan, interest = 8 percent and repayments = 304.15 dollars
Loan b
3 year loan, interest = 11 percent repayments = $491.08
Total number of repayments = 5 x 12 = 60
Total repayments = 304.15 dollars x 60
= $18249
The total interest that is paid for A would be
$18249 - $15000
= $3249
For the second loan
Total number of repayments = 3 x 12 months = 36
Total repayment = 36 x 491.08 = $17678.88
The total interest for the loan B would be: $17678.88 - $15,000
= $2678.88
Then the absolute difference between the paid loan would be
$3249 - $2678.88 = 570.12
Hence we would have the absolute difference that is between the loans paid as 570.

Write the equation of the line that passes through the point P (0, 0) and is perpendicular to the line y = – 2x + 10.
The equation of the line that passes through the point (0,0) and is perpendicular to the line y=-2x+10 is .
We will be using the concept of slope and equation of straight line for this question. Here it has been said that the line passes through (0,0) which is the origin, so we know the point ([tex]x_{1},y_{1}[/tex]) is (0,0).This point will be required while solving the equation for the straight line. The line is said to be perpendicular to another line given by y=-2x+10. When two lines are parallel their slopes are equal and when two lines are perpendicular the product of their slopes is equal to -1. The slope of a line can be found from the equation of the line by dividing the coeeficient of x by the coefficient of y.
Slope of y=-2x+10 is -2

X - y = 5 and x + y = -10
The value of x and y by using the given expressions is x = -5/2 and y = -15/2.
What is an expression?
An expression can be defined as the combination of variables and constants with two or more operations applied to it. The operation can be addition, subtraction, multiplication and division.
Simplifying the expressions for x and y
The given expressions are:
x - y = 5 —--- 1
x + y = -10 —---- 2
Adding the expression 1 and 2, we get,
2x = -5
x = -5/2
Subtracting the expression 1 and 2, we get,
-2y = 15
y = -15/2

40 Members of arwick youth club go on a trip to a leisure centre they go in minibuses that can each seat up to 15 people. It costs £30 for each minibus and £150 for the group to have use of the leisure centre. How much will the trip cost per person
The trip cost per person is 6 pounds.
What is a unit rate?Unit rate is the ratio of two different units, with the denominator as 1.
It means a rate for one of something.
We have,
Total members = 40
Each minibus cost = 30 pounds
Leisure centre cost = 150 pounds
Each minibus can carry = 15 people
The number of minibusses needed to carry 40 members:
= 40 / 15
= 2.67
= 3 minibusses.
This means we need 3 minibusses to carry 40 members.
Now,
The total cost for the trip:
= 150 pounds + 3 x 30 pounds
= 150 + 90
= 240 pounds
The cost per person:
= 240 / 40
= 6 pounds
Thus the trip cost per person is 6 pounds.

The translation of the points as Z' ( - 8 , - 3 ), K' ( - 7 , 0 ) and K' ( - 5 , 0 ).
We are given the translation as:
(x , y) → (x - 5 , y + 1)
Now we have some points:
Z (−3, –4)
K (−2, −1)
M (0, -1)
We need to translate these points.
For Z (−3, –4), we get the translation as:
Z (−3, –4) = Z' ( - 3 - 5 , - 4 + 1)
Z (−3, –4) = Z' ( - 8 , - 3 )
For K (−2, −1), we get the translation as:
K (−2, −1) = K' ( - 2 - 5 , - 1 + 1)
K (−2, −1) = K' ( - 7 , 0 )
For M (0, -1), we get the translation as:
M (0, -1) = K' ( 0 - 5 , - 1 + 1)
M (0, -1) = K' ( - 5 , 0 )
Therefore, we get the translation of the points as Z' ( - 8 , - 3 ), K' ( - 7 , 0 ) and K' ( - 5 , 0 ).

Michael grabs a marble from a bag. There are 5 green marbles and 1 red marble. If he grabs the red marble he loses everything he bet on. The marbles are not put back into the bag. The max amount of times Michael can bet on the same game is 4. If he bets 300 and wins 578 (having 278 as winnings), he has the choice to bet again with everything he earned for 682. Then he has the choice to do so again for 945, then 1312 at max. At what point in the game should Michael stop playing to gain the most given the percent of risk of losing the game? What point in the game is the least beneficial for Michael's gains?
First bet (300 -> 578)
Second bet (578 -> 682)
Third bet (682 -> 945)
Fourth bet (945 -> 1312)
If Michael wins every round he would go from 300 to 1312. If he loses, he doesn't gain any of the rewards and is 300 in debt.
Using the expected value of a discrete distribution, it is found that:
Michael should stop playing the game after the first round.The fourth round is the least beneficial round for Michael.What is the mean of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
For the probabilities, we consider that it is given by the number of desired outcomes divided by the number of total outcomes.
For one bet, the distribution is given as follows:
P(X = 578) = 5/6 (5 green marbles out of 6).P(X = -300) = 1/6.Hence the expected value is given by:
E(X) = 578 x 5/6 - 300 x 1/6 = $431.67.
For two bets, the distribution is given as follows:
P(X = 682) = 5/6 x 4/5 = 2/3.P(X = -300) = 1/3.Hence the expected value is given by:
E(X) = 682 x 2/3 - 300 x 1/3 = $354.67.
For three bets, the distribution is given as follows:
P(X = 945) = 5/6 x 4/5 x 3/4 = 1/2.P(X = -300) = 1/2.Hence the expected value is given by:
E(X) = 945 x 1/2 - 300 x 1/2 = $322.5.
For four bets, the distribution is given as follows:
P(X = 1312) = 5/6 x 4/5 x 3/4 x 2/3 = 1/3.P(X = -300) = 2/3.Hence the expected value is given by:
E(X) = 1312 x 1/3 - 300 x 2/3 = $237.33.
