Answer:
A function is a relation that maps inputs from a set called the domain, into outputs from a set called the range.
Such that each input can be mapped into only one output.
So for example, if we have a relation that maps the input 2 into two different values:
f(2) = 4
f(2) = 8
Then this is not a function.
In the case of the problem, we have a student as the input, and the hair color as the output.
So we will have something like:
f(student) = blond
And if this student decides to change his/her hair color to red?
Then the function becomes:
f(student) = red
So for the same input, we had two different outputs, which means that this is not a function.
We also could have the case where a given student has two colors (Californian for example)
Where again, we would see two different outputs for one single input.

For each triangle find the value of x
Answer:
x = 20
Step-by-step explanation:
The sum of the angles in a triangle is 180. A right triangle has one angle of 90. Thus, the sum of the other two angles will be 90. So, 90+31 = 121 and 180-121 = 59. (3x-1) = 59. Solve for x. This would mean that x would be 20. 3*20 = 60 and 60-1 = 59. All the angles add together would get 180: 59+90+31.

Mrs Fuller plants a 4 inch tomato plant in her garden. The tomato plant grows at a rate of 2 inches each week. Which equation can be used to determine h, the height of the tomato plant in inches after w weeks?
Answer: 4 + 2w
Step-by-step explanation:
The height of the tomato plant in inches after w weeks will be the value of the current height plus the weekly growth pee week. This can be represented in an equation as:
h = 4 + 2(w)
h = 4 + 2w
For example, the height of the tomato plant in inches after 5 weeks will be:
h = 4 + 2w
h = 4 + 2(5)
h = 4 + 10
h = 14 inches
What is the slope of the line?
Answer:
2
Step-by-step explanation:
To find slope just compare two points on a graph then put them into a fraction like so y₁ - y₂/x₁ - x₂

Anyone please me on this!!
Answer:
27 degrees
Step-by-step explanation:
So looking at this rhombus, we can make out 4 seperate traingles.
How many degrees are in a traingle? 180.
Looking at the traingle with z angle in it, we can see that it is a right traingle.
Now, lets subtract that 90 degrees from the 180.
This leaves us with the 63 degrees and x that make up the 90 degrees that are left.
Now all we have to do is subtract the 63 degrees from the 90 total degrees that we have left, and we will find out what z is equal to.
90 minus 63 is 27, so the angle of z is:
27 degrees
I hope this helps!
Note that I assumed these are right traingles, however I dont see how you can solve this without these being right trianlges, since you cannot use sin, cos, or tan to find this value without another angle or side length.

You preform a business service for which you charge $575. You receive $200 in cash and a promissory note for the balance, payable in 60 days. What steps will you use to show this transaction on your balance sheet?
Answer:
Cash is increased by $ 200 , and Notes Receivable is also increased by $ 375
Revenue Earned is also increased By $ 575.
Step-by-step explanation:
We make a journal entry
Cash $200 Debit
Notes Receivable $ 375 Debit
Services Revenue Earned $ 575 Credit
In the balance sheet the Cash is increased by $ 200 , and Notes Receivable is also increased by $ 375 on the Assets sides.
On the Liabilities side in the Owner's Equity section Revenue Earned is also increased By $ 575.
Increasing both sides ( Assets and Liabilities sections) with equal amounts will have no effect on the Balance Sheet .

At Raging River Sports, polyester-fill sleeping bags sell for $76. Down-fill sleeping bags sell for $141. In one week the store sold 17 sleeping bags for $1,460. $76$141Let x represent the number of polyester-fill bags sold and let y represent the number of down-fill bags sold. Complete the system of equations that can be used to find the number of each type sold. The system is braceleftze 76x + y = x + y =
Answer:
The system of equations that can be used to find the number of each type sold is given as:
x + y = 17 ...... Equation 1
76x + 141y = 1460....... Equation 2
Step-by-step explanation:
Let
x represent the number of polyester-fill bags sold
y represent the number of down-fill bags sold.
In one week the store sold 17 sleeping bags
x + y = 17 ...... Equation 1
x = 17 - y
At Raging River Sports, polyester-fill sleeping bags sell for $76. Down-fill sleeping bags sell for $141. In one week the store sold 17 sleeping bags for $1,460.
Hence:
$76 × x + $141 × y = $1460
76x + 141y = 1460....... Equation 2
Therefore, the system of equations that can be used to find the number of each type sold is given as:
x + y = 17 ...... Equation 1
76x + 141y = 1460....... Equation 2

2. What is the measure of angle AOE and angle EOD?
X+138
x + 48
Answer:
AOE = 138, EOD = 48
Step-by-step explanation:
Since AD is the diameter of the circle and goes through the middle
angle AOE + angle EOD = 180
Solving the equation (x + 138) + ( x+ 48) = 180
We get x = 0.

The sum of two numbers is 19 . When the second number is subtracted from the first number, the difference is 17 . Find the two numbers.
What are the two numbers?
Answer:
19 and 2
Step-by-step explanation:
Let x represent the first number and y represents second number
x + y = 19
x - y = 17 add two equations up
2x = 36 divide both sides by 2
x = 19 and since the difference is 17 the other number is 2
