k=2/7
Step-by-step explanation:
Constant of proportionality (k) can be found by using k=y/x
Substitute the y value (6) and the x value (21) into the equation.
Simplify: Divide 6 by 21 and come up with the answer k=2/7
Answer:
k=2/7

Are these functions: 1. In a class of ninth graders, the relationship between shoe size (x-axis) and height (y-axis). 2. in a class of ninth graders, the relationship between student (independent variable) and height (dependent variable).
Answer:
Your answer depends on the numbers showed to you.
Step-by-step explanation: To find your answer you need to look at the numbers on the x-axis are they the same repeating number each time(-1,9),(2,3),(4,-3)(-1,7) if they look like the example I just gave you then it is not a function. If the x-axis has all different number then yes it is a function.
The scenario 1 is not a function, while the scenario 2 is a function
How to determine the functions?Scenario 1:
The relationship is between:
The shoe size on the x-axisThe height on the y-axisIt is true that a certain shoe size can belong to students of different heights.
This means that the relation is a one-to-many relation
A one-to-many relation is not a function;
Hence, this is not a function
Scenario 2:
The relationship is between:
Independent variable: StudentDependent variable: HeightIt is true that a student can have only one height.
This means that the relation is a one-to-one relation
A one-to-one relation is a function;
Hence, this is a function

Kei has some money. Nozomi has three times as much money as Kei. Nozomi gave $10 to Kei. Now, Kei has $23 less than Nozomi. How much did Nozomi have at first?
Answer:
39$
Step-by-step explanation:
Because she gave Kei 10$ so you subtract 23 - 10 = 13 and thats the original that Kei had. Then you times 13 x 3 = 39. Thats your answer.
A little help here lol
Answer:
the last one
Step-by-step explanation:
Answer:
The 3rd answer.
Step-by-step explanation:
1. The absolute value of -6 is 6 so it does = the absolute value of 6.
I -6 I = 6 I 6 I = 6
2. Absolute value is the distance from that number and 0
I -6 I = 6
3. Since absolute value is the distance between that number and 0 it can not be the distance for 6 to -6.
4. This is how you write "absolute value of -6"
I -6 I = 6

(01.03) What number should be placed in the box to help complete the division calculation? (4 points) long division setup showing an incomplete calculation. 13 is in the divisor, 3302 is in the dividend, and 2 hundreds and 5 tens is written in the quotient. 2600 is subtracted from 3302 to give 702. An unknown value represented by a box is being subtracted from 702.
Answer:
i don't know if this is correct, but i think you place 2 in the box.
Step-by-step explanation:
you need to try to find the closetest multiple to find the division answer. so whichever one is closer is the one you need to use. mulitpy 2 to see if that's gets you anywhere, but something times 2 will get you 702. because if it ends in 2,4, or 6 it's a factor of 2. i hope this helps, but i'm not sure!

The length of a rectangle is 5 times larger than x. The width is 4 cm less than the length. The perimeter is at least 96 cm. What are the smallest possible dimensions for the rectangle?
We know that the perimeter of a rectangle = 2(l + w)
l = length
w = width
In our problem,
l = 5x
w = 5x - 4
Let's create an inequality to help us solve this problem.
2(5x + (5x - 4)) ≥ 96
Let's start off by simplifying the terms inside the parentheses.
2(10x - 4) ≥ 96
Distribute the 2
20x - 8 ≥ 96
Add 8 to both sides.
20x ≥ 104
Divide both sides by 20
x ≥ 5.2
Let's plug 5.2 into x for our length and width.
Length = 5x = 5(5.2) = 26 cm
Width = 5x - 4 = 5(5.2) - 4 = 26 - 4 = 22 cm
The smallest possible dimensions for the rectangle are, length = 26 cm and width = 22 cm
Answer:
width = 10 cm
length = 14 cm
The smallest dimension is 10 cm.
Step-by-step explanation:
2x + 2(x + 4) ≥ 48
Solve for x.
2x + 2x + 8 ≥ 48
4x + 8 ≥ 48
4x ≥ 40
x ≥ 10

Jessica was rock climbing. She was 42.8 feet above sea level. Jacob was swimming in the ocean below. He was 5.4 feet below sea level. How far apart were Jessica and Jacob?
SHOW WORK or i'll just take your answer off.
Answer:
48.2
Step-by-step explanation:
To solve this you can set up a number line.
1. Draw the number line and make sure it includes the numbers -5.4 (because Jacob is BELOW sea level), 0, and 42.8 (because Jessica is ABOVE sea level it will be positive)
2. On your number line make a shape or figure you are comfortable with above the -5.4 and 42.8 because this represents where they are in comparison to each other.
3. To figure out the distance between them both you can start at Jacobs spot and count the "notches" that indicate a new number on the number line all the way up to where Jessica is.
Equation Method
1. Set up the equation 42.8 + |-5.4| = x
In this case x is the total distance between Jessica and Jacob. You would use absolute value bars around -5.4 because you want to find his distance in relation to 0. You would add them, because you are trying to find the total distance between both of them.
2. Start to solve: 42.8 + 5.4 = x
If you are confused by absolute value bars I would reccomend watching a Khan Academy video explaining the topic.
3. 48.2 = x
Just add the numbers together. This will be your final answer.
