Answer:
A. y=1/3x+1
Step-by-step explanation:
When finding a line that is perpendicular to another line, all you have to do is find the "opposite reciprocal" of the slope. In this case that means writing the slope as the fraction -3/1, and then flipping the fraction over (1/-3) and taking away the negative sign which gets you 1/3 for the slope of your new line. Now, all you have of your new equation is the slope. You need to take your new equation (y=1/3x+b) and plug in the x and y coordinates to that equation, and then solve for the last variable which is b. That solving process goes as follows:
3=1/3*6+b
3=2+b
1=b
now you can replace the b with 1 in your equation to get your final answer of y=1/3x+1
A group of students would like to know how well the value of coins in a bag can be predicted based on their weight. They collected the following data.
Weight (grams) 32.7 -96.9- 93.8 65.4 65.4 79.7 69.3 112.1
Value $0.63 $3.22 $2.10 $2.17 $2.14 $2.03 $1.76 $3.19
For the bags of coins, what is the correlation coefficient, r , between "weight" and "value"? Use technology, and round your answer to the nearest hundredth.
Using a calculator, it is found that the correlation coefficient between weight and value is of -0.15.
Correlation coefficient:Has two inputs, which are the sets of values x and y.In this problem, the set x is composed by the weights.The set y is composed by the prices.Inserting these values in a calculator, it is found that the correlation coefficient between weight and value is of -0.15.

Answer:
4 and 5
Step-by-step explanation:
xy = 20
x + y = 9 ⇒ x = 9 - y
y(9 - y) = 20
9y - y² = 20
y² - 9y + 20 = 0
D = ( - 9)² - 4(1)(20) = 81 - 80 = 1
[tex]y_{1}[/tex] = (9 + 1) ÷ 2 = 5
[tex]y_{2}[/tex] = (9 - 1) ÷ 2 = 4
The numbers are 4 and 5

Solve for x when y=16.
3x+7=y
Answer: 3
Step-by-step explanation:
3x + 7 = y
3x + 7 = 16
*subtract 7 from both sides because inverse operations*
3x = 9
*divide both sides by 3 because inverse operations*
x = 3

find the slope
Answer:
3
Step-by-step explanation:
The difference between the y coordinates is 6.
The difference between the x coordinates is 2
The slope is rise over run so in this case, the rise is 6 and the run is 2.
This makes our slope:
6/2
This can be simplified to 3/1 so the slope is 3.

Is 18x-2y = 26 linear or non linear?
Answer: it’s a linear function
Step-by-step explanation:
18x-2y=26 as -2y= -18x + 26 by adding 18x to both sides, and then y=9x - 13 by dividing both sides by -2. So, it represents a linear function
Answer:
It's linear
Step-by-step explanation:
18x-2y=26
Because it has two variables x and y

Factorise the expression 6x^2-13x+6 and hence solve the equation 6x^2-13x+6=0
Answer:
Part A
The factored form of the expression, 6·x² - 13·x + 6 is (2·x - 3) × (3·x - 2)
Part B
The solution of the equation 6·x² - 13·x + 6 = 0 are x = 3/2 or x = 2/3
Step-by-step explanation:
Part A
The given expression to factorize is 6·x² - 13·x + 6, which can be written as follows;
6·x² - 13·x + 6 = 6·x² - 4·x - 9·x + 6
The 13·x is split at - 4·x - 9·x
6·x² - 4·x - 9·x + 6
2·x·(3·x -2) - 3·(3·x - 2)
Bringing out the common factor (3·x - 2) gives;
(2·x - 3) × (3·x - 2)
Therefore, the expression 6·x² - 13·x + 6 in factored form is (2·x - 3) × (3·x - 2)
Part B
Solving the equation, 6·x² - 13·x + 6 = 0, therefore gives;
6·x² - 13·x + 6 = (2·x - 3) × (3·x - 2) = 0
Therefore, either (2·x - 3) = 0 and x = 3/2 or (3·x - 2) = 0 and x = 2/3
From which we have 6·x² - 13·x + 6 = 0 when x = 3/2 or 2/3 and x = 3/2 or x = 2/3 are the solution of the equation 6·x² - 13·x + 6 = 0.
Chase wants to earn at least $900 this month in commission. What is the minimum amount he needs to sell in order to earn $900 if he earns a 3.3% commission on everything he sells? Round to the nearest dollar.
Answer:
$27,272.73= sales
Step-by-step explanation:
Giving the following information:
Desired commission= $900
Commission rate= 3.3% = 0.033 of sales
To calculate the sales required, we need to use the following formula:
Commission= sales*commission rate
900= sales*0.033
900/0.033= sales
$27,272.73= sales
Answer: $27,273
Step-by-step explanation: 900a=3.3100 Write the proportion. Let a represent the amount he needs to sell.
900a=3.3100 Because 3.3×272.72=900 , multiply 100 by 272.72 to find a.
90027.271=3.3100 100 × 272.72 ≈ 27,273, so a = 27,273.
Chase needs to sell $27,273 to earn $900 in commission.

simplify (y + 1)^5y + 1)^3
Note: Your expression sounds a little unclear, so I am assuming your expression is
[tex]\left(y\:+\:1\right)^5\times \left(y\:+\:1\right)^3[/tex]
But, the procedure to solve the expressions involving exponents remains the same, so whatever the expression is, you may be able to get your concept clear.
In the end, I will solve both expressions.
Answer:
Please check the explanation
Step-by-step explanation:
Given the expression
[tex]\left(y\:+\:1\right)^5\times \left(y\:+\:1\right)^3[/tex]
solving the expression
[tex]\left(y\:+\:1\right)^5\times \left(y\:+\:1\right)^3[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}[/tex]
[tex]\left(y+1\right)^5\left(y+1\right)^3=\left(y+1\right)^{5+3}[/tex]
[tex]=\left(y+1\right)^8[/tex]
Therefore, we conclude that:
[tex]\left(y\:+\:1\right)^5\times \left(y\:+\:1\right)^3=\left(y+1\right)^8[/tex]
IF YOUR EXPRESSION IS THIS
↓
[tex]\left(y\:+\:1\right)^{\left(5y+1\right)^3}[/tex]
solving the expression
as
[tex]\left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3[/tex]
so
[tex]\left(5y+1\right)^3=125y^3+75y^2+15y+1[/tex]
[tex]=125y^3+75y^2+15y+1[/tex]
Thus, the expression becomes
[tex]\left(y+1\right)^{\left(5y+1\right)^3}=\left(y+1\right)^{125y^3+75y^2+15y+1}[/tex]
Wesley is raising monarch caterpillars for a school science project. Every day, he feeds 7 fresh milkweed leaves to each caterpillar. Wesley wants to find out how many caterpillars he can feed in a day with a total of 42 leaves. Write an equation that can be solved for n to find the number of caterpillars he can feed in a day?
Step-by-step explanation:
Let n be the number of caterpillars.
Since each catepillar eats 7 leaves,
Wesley have 7n number of leaves.
In this case 7n = 42, so n = 6.
Answer: 7n = 42, n = 6.
Explanation:
Every caterpillar eats 7 milkweed leaves. That means [tex]n[/tex] is the number of caterpillars Wesley feeds every day. Since we know 7n is equal to 42, n = 6 because 42 ÷ 7 = 6.
