A function cannot send one input to more than one distinct output. You can think of this as passing the vertical line test – if you can draw a vertical line which passes through more than one point in a graph, it does not represent a function.
a. Not a function (there are several values of x that are sent to more than one value of y)
b. Not a function (-1 is sent to two different values of y)
c. Function (each value of x is sent to exactly one value of y)
d. Function (though 2 is listed as an input twice, the y-value is the same both times, so it is not sent to two different outputs)
e. Not a function (7 is sent to more than one different value)

Find the distance between the two points rounding to the nearest tenth (if necessary).
(-6, 6) and (-3,3)
Answer:
[tex]\boxed {\boxed {\sf d\approx 4.2}}[/tex]
Step-by-step explanation:
The formula for distance is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Where (x₁, y) and (x₂, y₂) are the points.
We are given (-6, 6) and (-3, 3). If we match the value and its corresponding variable, we see that:
x₁= -6 y₁ = 6 x₂ = -3 y₂ = 3Substitute the values into the formula.
[tex]d= \sqrt{ (-3 - -6)^2+(3-6)^2[/tex]
Solve inside the parentheses.
-3 --6 = -3+6 = 33-6 = -3[tex]d= \sqrt{(3)^2+ (-3)^2[/tex]
Solve the exponents.
(3)²= 3*3= 9 (-3)²= -3*-3 =9[tex]d= \sqrt{9+9[/tex]
Add.
[tex]d= \sqrt18[/tex]
[tex]d= 4.24264069[/tex]
Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 2 in the tenth place.
[tex]d \approx 4.2[/tex]
The distance between the two points is apprximately 4.2

Sherelle and Venita find two bags of coins in their grandmother’s attic. Each girl selects a bag, takes a random sample of 20 coins from that bag, and lists the dates of those coins as the number of years since 1900. Here are the results.
Sherelle: 72, 56, 81, 84, 75, 26, 39, 62, 65, 66, 85, 71, 74, 68, 73, 66, 83, 60, 58, 72
Venita: 45, 65, 73, 57, 79, 66, 69, 75, 51, 44, 53, 69, 58, 77, 51, 55, 53, 78, 70, 62
1. Find the five-number summary of each data set. Then construct box-and-whisker plots of the data sets. Draw both plots above the same number line. Label the plots with the girls’ names.
Answer:
hope this helps sweetie :)
Step-by-step explanation: So first what you want to do find the data sets. You can do that by crossing out the numbers to find the median which would be in the very middle. Then draw the box and whisker plot, and boxes around each number. this should give you everything you need to draw the number line and label the plots.
Answer:
Sherelle: Venita:
minimum = 26 minimum = 44
maximum = 85 maximum = 79
First Q. = 60.5. First Q. = 53
Third Q. = 74.75 First Q. = 72.25
Median = 69.5. Median = 63.5

2. X 0 4 7 10 13 y -5 -5 -5 -5 -5 Domain: ______________________ Range: _______________________ Function? _______
Answer:
[tex]Domain =\{0,4,7,10,13\}[/tex]
[tex]Range = \{-5\}[/tex]
[tex]y = -5[/tex] --- function
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}x & {0} & {4} & {7} & {10} & {13} \ \\ y & {-5} & {-5} & {-5} & {-5} & {-5} \ \end{array}[/tex]
Solving (a): The domain
The x values represent the domain.
Hence, the domain is:
[tex]Domain =\{0,4,7,10,13\}[/tex]
Solving (b): The range
The y values represent the range
Hence, the range is:
[tex]Range = \{-5\}[/tex]
Solving (c): The function
By observation, we can see that for all values of x the value of y remains unchanged (-5)
Hence, the function is:
[tex]y = -5[/tex]
what is volume of rectangular pyramid with bases 6.3 mm and 2.4 mm and height 3.6 mm
Answer:
18.144 mm3
Step-by-step explanation:
V = l * w * h / 3
V: volume
I: base length
w: base width
h: pyramid height
Now, put the values in the formula to form an equation and solve it.
V = l * w * h / 3
= 6.3 * 2.4 * 3.6 / 3
= 18.144 mm3

After solving the system x+2y=10 and x-2y=2. What is the sum of x+y equal to?
Answer:
The sum of x and y is 8.
Step-by-step explanation:
x+2y=10
x-2y=2
------------
2x = 12, so x = 6. Substituting 6 for x in the 2nd equation, we get:
6 - 2y = 2, or
4 = 2y, or y = 2. The solution is therefore (6, 2).
The sum of x and y is 6 + 2 = 8 (answer)
Answer:
6 + 2 = 8
Step-by-step explanation:
[tex]x + 2y = 10 \\ + \\ x - 2y = 2 \\ = \\ 2x = 12 \\ x = 6 \\ 6 + 2y = 10 \\ 2y = 4 \\ y = 2 \\ x + y = 6 + 2 = 8[/tex]

James goes out to eat with Janet, and their meal costs $68. There is a sales tax of 7% and Janet wants to leave a 20% tip. How much money will Janet spend on the entire meal?
Answer:
$86.36
Step-by-step explanation:
Tax: 7%, or 0.07
Tip: 20%, or 0.2
Substitute the values:
Tip: 68 * 0.07 = 4.76
Tip: 68 * 0.2 = 13.6
Just the meal cost: 1 * 68 = 68
Add these all together
4.76 + 13.6 + 68 = 86.36
Thus, the total cost of the meal would be $86.36

Sum of place value and face value of 5 in 75897 is
Given:
The number is 75897.
To find:
The sum of place value and face value of 5 in the given number.
Solution:
The given number is:
75897
The face value is 5 is always 5.
The number of is 5 on thousands place. So, the place value of 5 is:
[tex]5\times 1000=5000[/tex]
The sum of place value and face value of 5 in the given number is:
[tex]5000+5=5005[/tex]
Therefore, the sum of place value and face value of 5 in the given number is 5005.
Mary bought 5/6 of a foot of blue ribbon and 2/3 of a foot of yellow ribbon. she used a combined total of 1/2 foot of ribbon to make bows. how much ribbon does she have left?
Answer:
3/4
Step-by-step explanation:
2/3 = 4/6 so 5/6 plus 4/6 = 1 3/6 then divide by 2, it will give u 0.75 in decimal form which is simplifyed to 3/4, so 3/4 is the answer.

Use the Pythagorean Theorem to find the missing length and then round the
result to the nearest tenth.
b = 2, c = 3
a =
Answer:
A=2.2
Step-by-step explanation:
PYTHAGOREAN THEOREM:
a^2+b^2=c^2
STEP 1:
Lets put in the given number into the Theorem.
x^2+ 2^2= 3^2
I put x in the "a" place because there is no Number that goes into there, so we put in a variable.
STEP 2:
We find the numbers, which are
x^2+4=9
STEP 3:
We then subtract by 4 from both sides, (We do this because x is not the Hypotenuse)
After subtracting from both sides we have
x^2=5
STEP 4:
Once we have that, we have to find the square root of 5 which is 2.23606798
STEP 5:
Since you say to round to the nearest tenth, we get 2.2
TIP: If the answer didn't have to be rounded to the nearest tenth the answer would've been: [tex]x=\sqrt{5}[/tex] Which is the same as 2.23606798.

By intersecting chords theorem:
[tex] AE \times EB = CE \times ED[/tex]
[tex] \therefore 3 \times 4= x \times (x+1)[/tex]
[tex] \therefore 12= x^2 +x[/tex]
[tex] \therefore x^2 +x-12=0[/tex]
[tex] \therefore x^2 +4x-3x-12=0[/tex]
[tex] \therefore x(x +4)-3(x+4)=0[/tex]
[tex] \therefore (x +4)(x-3)=0[/tex]
[tex] \therefore (x +4)=0, \: (x-3)=0[/tex]
[tex] \therefore x=-4, \: x=3[/tex]
Since, the value of x can not be negative.
[tex] \therefore x\neq - 4[/tex]
[tex] \implies x = 3[/tex]
[tex] \implies CE = 3[/tex]
