Determine if the graph shows two quantities that vary directly. If possible, determine the constant of proportionality using the formula K = y/x
Answer:
Option C is correct option.
Step-by-step explanation:
We need to find k constant of proportionality
In the graph below let us take the values of x and y
x=150 , y=50
x=300, y=100
x=450, y=150
Now finding k using the formula: [tex]k=\frac{y}{x}[/tex]
Putting values of x and y to find k
For x=150 , y=50 k = 50/150, k =1/3
For x=300, y=100 , k=100/300 , k=1/3
For x=450, y=150, k= 150/450 , k=1/3
Since for values of x and y, k = 1/3 is constant so, the graph shows two quantities that vary directly.
So, Option C is correct option.

A line has a slope of 6 and includes the points (n,1) and (8,5). What is the value of n?
Answer:
The value of n:
[tex]n=\frac{22}{3}[/tex]Step-by-step explanation:
Given that the line has slope 6.
i.e. m = 6
The line includes the points
(n, 1)(8, 5)Using the formula to find the slope of the points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(n,\:1\right),\:\left(x_2,\:y_2\right)=\left(8,\:5\right)[/tex]
[tex]m=\frac{4}{8-n}[/tex]
as
m = 6
substituting m = 6
[tex]6=\frac{4}{8-n}[/tex]
[tex]6\left(8-n\right)=4[/tex]
Divide both sides by 6
[tex]\frac{6\left(8-n\right)}{6}=\frac{4}{6}[/tex]
[tex]8-n=\frac{2}{3}[/tex]
subtract 8 from both sides
[tex]8-n-8=\frac{2}{3}-8[/tex]
simplify
[tex]-n=-\frac{22}{3}[/tex]
Divide both sides by -1
[tex]\frac{-n}{-1}=\frac{-\frac{22}{3}}{-1}[/tex]
[tex]n=\frac{22}{3}[/tex]
Therefore, the value of n:
[tex]n=\frac{22}{3}[/tex]

7. There are 19 red marbles for every black marble. If there are 120 marbles in the bag, how many red marbles are there? Explain or show your reasoning.
Answer:
114 marbles.
Step-by-step explanation:
Let the number of red marbles be r
Let the number of black marbles be b
Given the following data;
Total number of marbles = 120
Translating the word problem into an algebraic equation, we have;
[tex] r = 19b[/tex] .......equation 1
[tex] r + b = 120[/tex] ........equation 2
Substituting the value of "r" into equation 2, we have;
[tex] 19b + b = 120[/tex]
[tex] 20b = 120[/tex]
[tex] b = \frac {120}{20}[/tex]
b = 6 marbles.
To find the number of red marbles;
From equation 1;
[tex] r = 19b[/tex]
Substituting the value of "b" into equation 1, we have;
[tex] r = 19*6[/tex]
r = 114 marbles.
Therefore, there are 114 red marbles in the bag.

3 (x – 4) = 2x + 6
solve for x
Answer:
Step-by-step explanation:
3 (x – 4) = 2x + 6 Remove the brackets
3x - 12 = 2x + 6 Add 12 to both sides.
3x - 12 + 12 = 2x + 6 + 12 Combine
3x = 2x + 18 Subtract 2x from both sides
3x-2x = 2x-2x + 18 Combine
x = 18

what is Inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given:
A number line going from negative 1 to 1.
One-half less-than one-third
i.e., 1/2 < 1/3 is true
and, Three-fourths greater-than two-thirds
i.e., 3/4 > 2/3 is true
and, Negative one-fourth less-than negative two-thirds
i.e., -1/4 < -2/3 is false
and, Negative 1 greater-than three-fourths
-1 > -3/4 is true.

what is the slope kf the line that passes through (5,-11) and (-9,17)
Answer:
The slope is:
[tex]m=-2[/tex]
Step-by-step explanation:
Given the points
(5, -11)(-9, 17)Finding the slope between the points using the formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-11\right),\:\left(x_2,\:y_2\right)=\left(-9,\:17\right)[/tex]

Ben needs to buy an equal number of sunglasses and beach balls to place in gift bags. Each pair of sunglasses costs $4 and each beach ball costs $2.50. If he has $45 to spend on the sunglasses and beach balls, then the inequality 4x + 2.5x greater than or equal to 45 can be used to find the number of each item he can buy. How much money will he have left after buying the greatest number of sunglasses and beach balls?
$0.09 will he have left after buying the greatest number of sunglasses and beach balls.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Model Inequality: 4x + 2.5x ≥ 45.
Now, solving for inequality
4x + 2.5x ≥ 45.
(4 + 2.5)x ≥ 45
6.5x ≥ 45
x ≥ 45/ 6.5
x≥ 6.92
x≥ 7 (approx)
So, the max price for sunglasses and beach balls = 4(6.92)+ 2.5(6.92)
= $44.91
Thus, the left money is = 45- 44.91 = $ 0.09

Laura needed an electrician to provide electrical repairs in her kitchen. The electrician will charge Laura x dollars per hour for a 5-hour job and $20 for electrical parts, and also $50 for a new ceiling fan. Write an algebraic expression in simplest form to determine how much the electrician will charge Laura.
Give the expression and answer please
Answer:
The answer is 50x + 70
Step-by-step explanation:
I am happy to help. An expression has no equal sign. We don't know how much the electrician will charge Laura. But we do know how much hours the job is. Laura also has to pay for the electrical parts that are 20 dollars and 50 dollars for a new ceiling fan. This is an additional cost. In all, the expression would be 50x + 70, if it is simplified. You would add like terms, such as 20 and 50 to get 70.
