L1 and L2 are parallel lines
the equation of L1 is y= 3x + 2
L2 passes through the point (3,4)
find an equation for L2

Answers

y = 3x + 2. The slope here is 3. A parallel line will have the same slope.

y = mx + b
slope(m) = 3
(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = 3(3) + b
4 = 9 + b
4 - 9 = b
-5 = b

so ur other line, L2 is : y = 3x - 5 <==
The slope for 2 parallel lines is always the same so the slope will remain 3.(m=3)
To find the y intercept you have to replace the y and x with the 2 points given and the m with the slope and simplify.
so, y=mx+b
(4)=(3)(4)+b
4=12 +b
8=b
then plug in the intercept and the slope into the slope intercept equation and there is your answer.
y=3x+8

Factor expression 42x+49

Answers

Final answer:

To factor the expression 42x+49, we find the GCF which is 7, and express the expression as 7(6x + 7).

Explanation:

The question focuses on the task to factor the expression 42x+49. Factoring is a mathematical process in which we express a number or an algebraic expression as the product of its factors, which are usually simpler or more basic expressions.

To factor the given expression, we look for the greatest common factor (GCF) that both terms share. In this case, the GCF of 42x and 49 is 7. We factor the 7 out:

42x + 49 = 7(6x + 7)

The factored form is 7(6x + 7), which is the simplest form of the expression where 7 is a common factor multiplied by the binomial 6x+7.

5^2-11 over 6(3). Evaluate the expression. A. 7. B. 2/9. C.-1/63. D. 7/9

Answers

The first thing you do is exponents, so you get (25-11)/6(3). After that simplify the denominator to 18. So, you get (25-11)/18. When you subtract the numerator you get 14/18. This reduces to 7/9.

So the answer is D, 7/9.

Describe some data that when graphed would represent a proportional relationship. Explain your reasoning

Answers

The lines would go up and over at the same rate. They would have the same slope, like parallel lines.

Hope this helps!! :)

Answer:

A proportional relationship is "two quantities vary directly with each other."

Example:

The amount of gasoline you fill in your car and the amount you pay is a proportional relationship.

If 1 gallon of gasoline is $3, then the cost of 3 gallons of gasoline is $9.

Step-by-step explanation:

A relationship is between two quantities.

A proportional relationship is "two quantities vary directly with each other."

Say, if the quantity "x" increases, then the associated quantity "y" also increases.

For example,

y = 2x

Let's find the data.

x                y

0                 0

1                  2

2                 4

3                  6

As you can see when the value of "x" increases, the value of "y" also increases.

This is called proportional relationship.

Example:

The amount of gasoline you fill in your car and the amount you pay is a proportional relationship.

If 1 gallon of gasoline is $3, then the cost of 3 gallons of gasoline is $9.

Each day, Jake donates money to the global hunger initiative according to how many lunch specials he sells. What is the constant of proportionality in money per lunch special?

Answers

Since it's y/x, and x is what you input into the function (and y is what you get out), we get that the amount donated is based off of the lunch specials, so we get y(12)/x(60)=12/60=1/5

Answer: 1/5

Explanation: Since, according to the given figure,

Jake spends money for 60 lunch special= 12 unit

Therefore, In this case, money per lunch= 12/60=1/5

Jake spends money for 45 lunch special=9 unit

Therefore, In this case, money per lunch= 9/45=1/5

Jake spends money for 30 lunch special=6 unit

Therefore, In this case, money per lunch= 9/45=1/5

Again, Jake spends money for 15 lunch special=3 unit

Therefore, In this case, money per lunch= 3/15=1/5

Thus, from the above explanation it is clear that the money per lunch is same for every condition and is equal to 1/5.

The school’s guidance department compares the grade-point averages and standardized state test scores for 10 students in each grade. The table below shows the correlation coefficient for each data set.


Answers

Ok, so to see which data sets is reasonable for a linear regression model square each set and if it is close to one it will be reasonable. 

[tex]r^{2}[/tex]
9th grade 0.3 = [tex]0.3^{2}[/tex] = 0.09
10th grade –0.1 = [tex]-0.1^{2}[/tex] = 0.01
11th grade 0.2 = [tex]0.2^{2}[/tex] = 0.04
12th grade –0.8 = [tex]-0.8^{2}[/tex] = 0.64

So 12th grade data set is reasonable but the others are not because they are not remotely close to 1.



The 12th-grade data set represents the linear regression because the value of the correlation coefficient for the 12th-grade students is near the -1 which shows a perfect negative linear regression

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

The correlaton coeffiecient is given as below:

For 9th grade = 0.3

For 10th grade = -0.1

For 11th grade = 0.2

For 12th grade = -0.8

We know that for perfect linear regression the value of the correlation coefficient is 1 or -1

As we can see from the data given the nearest value of the correlation coefficient is -0.8 which is the correlation coefficient for the 12th grade.

Thus, the 12th-grade data set represents the linear regression because the value of the correlation coefficient for the 12th-grade students is near the -1 which shows a perfect negative linear regression.

find the measure of an angle whose supplement measures seventeen times its measure

Answers

supplement angles, sum = 180
lets x =  angle
its supplement = 180 - x

x + 17x = 180
18x = 180
x = 10
180 -10 = 170

answer
angle = 10
its supplement  = 170

Final answer:

The measure of an angle whose supplement is seventeen times larger than the angle itself is 10 degrees.

Explanation:

We are looking to find the measure of an angle that is said to have its supplement measure seventeen times larger than the angle itself. In terms of mathematical relationships, this means that if we call the angle in question x, then its supplement would be 17x. We know that supplementary angles add up to 180 degrees, hence we can write the equation x + 17x = 180. By solving this equation, we find that 18x = 180, and therefore x = 180÷18 which simplifies to x = 10. So the measure of the angle we are looking for is 10 degrees.

Please explain how to do this

8% x 4.50
=0.08 x 4.50

What is a ratio?

A ratio is a comparison of two attributes of a similar kind.

Based on the random sample, the number of students doing household chores for at least two hours every week =64+3+1 =68

Out of 100, the number of students doing household chores for at least two hours every week = 68

So, out of 1, the number of students doing household chores for at least two hours every week = 68/100

So, out of 1500, the number of students doing household chores for at least two hours every week = (68/100)*1500 =1020

Thus, there will be 1020 students in the school doing household chores for at least two hours every week.

For 34, since each diameter is in scientific notation , meaning that we have one number (1-9) followed by a decimal, we simply see which has the smallest power, which is cell C.

For 35, we multiply them out to get 0.83*10^2 (we subtract exponents when dividing). Since scientific notation is one integer from 1-9 followed by a decimal, we move 0.83 one place to the right and therefore remove one power from 10^2, getting 8.3*10

This is a simple equation; "x" is the first number and (5+2x) is the second number because it is "5 more than twice the first" and the sum = 80. So... x + (5+2x) = 80 You start by subtracting "x" and moving it to the other side...5 + 2x = 80 - x Then you add the "x" to the other side...5 + 3x = 80 Next, subtract 5 to the other side...3x = 75 Finally, divide the 3 to the other side...x = 75/3...x = 25 25 is the first number so you then multiply it by 2 and add five to get the final answer. 25 + 55 = 80
