If the graphs relation is a function it will never repeat its x-values. In a function, there should only be 1 output(y) for each single input(x). Each x must correspond with only one y value.

what is the slope of the line?
Answer:
No Solution
Step-by-step explanation:
Slope is rise/run
rise = 1
run = 0
you can't divide by 0 so no solution
Answer:
The slope of the line is undefined.
Step-by-step explanation:
The slope of a line is given by [tex](y_2-y_1)/(x_2-x_1)[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points on the line. Since this is a vertical line, [tex]x_2-x_1[/tex] will, however, be equal to zero. We cannot divide by zero, so the slope of the line is not defined.

25. Write an expression to represent the area of the shaded region in simplest form.
5x + 2
x + 7
3x - 1
Answer:
Step-by-step explanation:
To determine what the area of the shaded region is, simply find the area of the large rectangle and subtract the product from the smaller one.
Since they are polynomials. Multiply one binomial to the other and first obtain the product, before subtracting the product of the smaller rectangle.
(5x + 2)(3x - 1) - (x)(x + 7)
15x^2 - 5x + 6x - 2 - x^2 - 7
14x^2 + x - 9.
I believe this would be the solution in standard form.

Ethan works at an electronics store as a salesperson. Ethan earns a 5% commission on the total dollar amount of all phone sales he makes, and earns a 4% commission on all computer sales. Ethan had twice as much in computer sales as he had in phone sales and earned a total of $117 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Ethan made and the dollar amount of computer sales he made. Define the variables that you use to write the system.
Answer:
0.05x+0.04y=117
y=2x
where:
x is the amount of all phone sales
y is the amount of all computer sales
Step-by-step explanation:
From the information given, the first equation would indicate that the comission of all phone sales plus the comission from all computer sales would be equal to 117, which is:
0.05x+0.04y=117, where:
x is the amount of all phone sales
y is the amount of all computer sales
Also, the statement indicates that Ethan had twice as much in computer sales as he had in phone sales, which would be:
y=2x
Now, you can replace y=2x in the first equation and solve for x:
0.05x+0.04(2x)=117
0.05x+0.08x=117
0.13x=117
x=117/0.13
x=900
Finally, you can replace the value of x in y=2x to find the value of y:
y=2(900)
y=1800

Please help !! Which statement best describes the data ?
Answer:
The correct statement is C.
Step-by-step explanation:
A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,
1. Minimum (shown towards the left of the chart)
2. First Quartile (shown by the left-most line of the box)
3. Median (or the second quartile) (shown as a line in the center of the box)
4. Third Quartile (shown by the right-most line of the box)
5. Maximum (shown towards the right of the chart).
From the provided box plot it can be concluded that:
Minimum = 3First Quartile = 6Median = 9Third Quartile = 12Maximum = 15The median is a quantity in statistics that points out where the mid-value of a data set is. Half of the data is less than the median and half is more than the median.
The median is 9, i.e. half of the data is less than 9 and half is more than 9.
The correct statement is C.
Use the order of operations to evaluate: −7.6 − 2[9 + (−6.8)] First, simplify the parentheses: [9 + (−6.8)] = 2.2. Now the expression is: −7.6 − 2(2.2). Since there are no exponents in this problem, the next step is ✔ (- 2)2.2 . Simplify the previous step and you get ✔ -7.6 – 4.4 . The final answer is
Answer:
-12.0
Step-by-step explanation:
From the above question, we are given:
−7.6 − 2[9 + (−6.8)]
We apple the PEDMAS rule
P = Parentheses, Hence:
Step 1
The first step is to simplify the parentheses
[9 + (−6.8)] = 2.2.
Step 2
We now have:
−7.6 − 2(2.2).
Step 3
We simplify Parentheses again
(- 2)2.2 = -4.4
Step 4
We simplify
-7.6 - 4.4
= -12.0
The final answer is 12.0

Answer:
Monica = 48.50
Samuel = 24.25
Kara = 17.25
Step-by-step explanation:
First you write equations as you are reading the text:
m = 2s ("Monica earned twice as much as Samuel")
s = k+7 ("Samual earned 7 more than Kara")
m = 48.50
Next, you convert these equations to solve for s and k respectively.
So, if m=2s, then s=m/2:
s = m/2 = 24.25
Likewise, if s=k+7, then k=s-7
k = s-7 = 17.25
The difference between greatest and least is 48.50 - 17.25 = 31.25

Substitution Method
For x:
[tex]y = \frac{5}{4}x - 2\\y = -\frac{1}{4}x + 19\\\\\frac{5}{4}x - 2 = -\frac{1}{4}x + 19\\\\\frac{3}{2}x - 2 = 19\\\\\frac{3}{2}x = 21\\\\x = 14[/tex]
For y:
[tex]y = \frac{5}{4}(14) - 2\\\\y = 17.5 - 2\\\\y = 15.5[/tex]

Find the probability of the following situation.
A cooler contains thirteen sports drinks:
six lemon-lime and seven orange. Two of
the lemon-lime and four of the orange
drinks are cold. The others are still warm.
You randomly grab a bottle. It is orange
flavored or warm.
Answer:
11/13
Step-by-step explanation:
"six lemon-lime and seven orange"
"Two of the lemon-lime and four of the orange drinks are cold"
2 lemon-lime are cold
4 lemon-lime are warm
4 orange are cold
3 orange are warm
Total orange flavored: 7
Not orange warm: 4
orange or warm: 11
p(orange or warm) = 11/13
The probability of grabbing a bottle that is orange flavored or warm is [tex]\frac{11}{13}[/tex]
What is probability?'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'
According to the given problem,
Total number of drinks = 13
Number of lemon-lime drinks = 6
Number of orange drinks = 7
Number of drinks that are cold = 2 lemon-lime + 4 orange
= 6 drinks
Number of drinks still warm = 7
Probability = [tex]\frac{Number of possible events}{Total number of events}[/tex]
= [tex]\frac{7 + 4 }{13}[/tex] [ 7 + 4 because 7 are orange flavored and 4 lemon-lime
drinks are warm.]
= [tex]\frac{11}{13}[/tex]
Hence, we can conclude, the probability of grabbing a bottle that is orange or warm is [tex]\frac{11}{13}[/tex].
