A taxi service charges $1.00 for the first 1/10 mile then $0.10 for each additional 1/10 mile after that.
Answer:
y = 1.00+0.10 x
Step-by-step explanation:
Given that a taxi has a minimum charge of 1 dollar upto 1/10 mile and adds 0.10 for every additional 1/10 mile.
If a person travels <=1/10 miles his charges are 1 dollar
If he travels >1/10 miles charges are 1 dollar +0.10(extra miles 1/10)
Let y be the charges and x be the no of 1/10 miles.
Then the equation for y in terms of x would be
y =1.00 +1/10(x)
y = 1.00+0.10 x
Evaluate

The cost of coffee is determined by the type of coffee beans that are mixed together. The cost of a local mix of arabica and robusta beans is modeled by the equation below, where a = the pounds of arabica and r = pounds of robusta: (2 points) 700a + 1200r = 1,000,000 if a mixture contains 1000 pounds of arabica beans, how many pounds of robusta beans should be in the mixture? R = pounds
700a + 1200r = 1,000,000
700(1000) + 1200r = 1,000,000
700,000 + 1200r = 1,000,000
1200r = 300,000
r = [tex]\frac{300,000}{1200} = \frac{3000}{12} = 250[/tex]
Answer: 250 pounds of robusta beans

Does This. Graph Represent A Function? Why Or Why Not?
Answer: D. Yes because it passes the vertical line test.
Step-by-step explanation
A function cannot have duplicate x-coordinates.
When given a table or a set of coordinates, if there is an x-coordinate that is paired with two different y-coordinates then it is not a function.
When given a graph, the simplest way to determine if it is a function is to use the vertical line test. If you can draw a vertical line anywhere through the graph and it passes through two points, then it is not a function.
In the given graph, it passes the vertical line test so it IS a function.

Answer:
Your answer is B or option 2.
Step-by-step explanation:
When doing scale factors, you will multiply. Always. To get from the original box to the second box, you will multiply by a scale factor of 5/8. An equation can model this. b=5/8a. (Let a = dimensions of original/blue box, let b = dimensions of second/green box).
Since you need to find the dimensions of the first/original box, you need to change b=5/8a to a= [something]. To do that, divide both sides by 5/8. You have b / 5/8 = a. The dimensions of the second box divided by the scale factor 5/8 is the dimensions of the first box. This also makes sense, because the green box looks smaller than the blue box. Hope I helped! This is a challenging subject to explain properly. ^_^"
oh yeah kekeke my name is pizaz/pzaz, what a coinkidink
The answer is D.
Since the original rectangle is bigger, we are going to divide the dimensions in the smaller triangle by the scale factor 5/8. An easy hint to look at in this question is an answer choice that both dimensions are bigger than the dimensions of the smaller rectangle. All the other choices are incorrect because the dimensions of the original triangle are not bigger than that of the smaller triangle which makes them false.
Best of Luck!

Enter a recursive rule for the geometric sequence.
2, 6, 18, 54, …
a1= ; an=
Answer:
Step-by-step explanation:
Given a geometric sequence.
2, 6, 18, 54, …
We have to find the I and nth term.
A geometric sequence. is one where each term is multiplied by a constant value to get the next term.
In our sequence, we find the pattern as each term is multiplied by 3 to get successive terms.
Hence common ratio r = 3
First term = a = 2
For Geometric sequence nth term = a_n = ar^(n-1)
Hence we get a_1 = 2
and a_n = 2(3)^(n-1)
By substituting for n any natural number we can get that term.

Use the substitution method to solve the system of equations. 3x + 7y = 1 y = x – 7
A. (3, –4)
B. (4, –3)
C. (2, –5)
D. (5, –2)
Answer: The correct option is (D) (5, -2).
Step-by-step explanation: We are given to use the method of substitution to solve the following system of equations :
[tex]3x+7y=1~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\y=x-7~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]
Substituting the value of y from equation (ii) in equation (i), we get
[tex]3x+7y=1\\\\\Rightarrow 3x+7(x-7)=1\\\\\Rightarrow 3x+7x-49=1\\\\\Rightarrow 10x=50\\\\\Rightarrow x=\dfrac{50}{10}\\\\\Rightarrow x=5,[/tex]
and from equation (ii) again, we get
[tex]y=x-7=5-7=-2.[/tex]
Thus, the required solution is (x, y) = (5, -2).
Option (D) is CORRECT.
What are the domain and range of the function below?
Answer:
Domain is the set of all real numbers
Range is the set of all real numbers.
Step-by-step explanation:
Given a graph with curve which has y intercept -5, and x intercept 5.
The graph is continuous at all points of x and y
We find that the graph is a straight line with positive slope of the form
x/5 +y/-5=1
Or x-y =5
The graph is defined for all values of x and y.
The domain is the set of values x can take
In the graph horizontal axis is x axis.
Hence from the graph we see that x can take values from -infinity to + infinity
Hence domain is x = R
For range, we consider the values of y as per graph.
WE find that y is taking values in the interval (-infinity, infinity)
Hence Range =R
The term 'domain' in mathematics refers to the complete set of possible values of the independent variable in a function. The 'range' on the other hand, represents the possible results of the function after an experiment or survey. These values are not always numerical but could be a set of words or phrases.
Explanation:The domain of a function is the complete set of possible values of the independent variable. In the context of your question, it can be a list such as X = {English, Mathematics,...} representing all the majors offered at a university, or it can be a numerical set, for example Y = {0, 1, 2,...} representing the integers from zero up to the upper limit of classes. Even functions like Z where the domain includes any amount of money from zero upwards can exist.
Similarly, the range of a function is the set of all possible values that the function can take after the experiment is performed or the question is answered. For instance, if a function has a domain of hair color, its range would be the different hair colors like black, blond, gray, green, orange, etc. This shows that the domain and range of a function are not necessarily numerical.
The specific value x the function takes only becomes known after performing the experiment or survey. However, there might be certain values that are outside the domain of the function and as such, would not give a reliable prediction, just like 90 in the dataset from 65 to 75. Such an occurrence doesn't fall within the domain of the function and can't be accurately predicted.

Which methods can be used to expand (x+3)3?
Which methods can be used to expand (x+3)3?
Solution
Here use the Distributive Property of Multiplication Across the Addition.
The Distributive Property is a.(b + c) = a. b + a.c
Using the distributive property, we can expand the given expression.
(x + 3).3 = 3.x + 3.3
That is the expanded form.
The expression (x+3)³ can be expanded by using the binomial expansion method or by multiplying (x+3) by itself three times. This involves using binomial coefficients and combining like terms or calculating the products directly and simplifying the resulting expression.
To expand (x+3)³, we can use binomial expansion, which involves recognizing the pattern of coefficients that arise from Pascal's Triangle or using the binomial theorem. Another way is to multiply (x+3) by itself three times. In both methods, you calculate the products and combine like terms to get the final expanded form.
For cubing of exponentials, such as cubing (x+3), you must calculate each term of the binomial raised to the third power and then combine like terms. The cube of the digit term is calculated as usual, and you multiply the exponents by 3 when dealing with exponential terms.
An example of this concept applied to individual exponentials is: (5³)⁴ = 5³*⁴ = 5¹². In our case of binomial expansion, the expanded form of (x+3)³ would be x³ + 3*x²*³ + 3*x*3² + 3³, which simplifies to x³ + 9*x² + 27*x + 27.

Which graph represents a function?
The graphs will be below the question.
C (third graph, the parabola); To find if it is a function or not draw a vertical line on the graph. If the vertical line could never intercept the figure more than once anywhere on the graph then it is a function.
From left to right of the pictures it's the 3rd photo. It's the 3rd photo because it passes the vertical line test witch means if a vertical line was drawn within the middle of the graph it would only pass through one line and not two. The other ones would pass through two lines instead of one. I hope this helped you!
