Does the graph represent a function? Why or why not?
Answer:
Yes
Step-by-step explanation:
Because any vertical line drawn doesn't meet the graph at two points.
So this concludes that there is a single output for any input. Which is the basic requirement for a function

Step-by-step explanation:
Given h(x) = 4x + 5 solve for when h(x) = 9 .
Answer:
3x = 5
Step-by-step explanation:
9x = 4x + 5
-4x -4x
3x = 5
Answer:
h(x) = 4x + 5 h(x) = 9
9 = 4x + 5 9 - 5 = 4 and 5 - 5 = 0
4 = 4x 4 divided by 4 equals 1
Answer is x = 1.
--------------------------------------------------------
Check your answer:
9 = 4x + 5
Input the 1 into the variable x's place in the equation.
9 = 4 X 1 + 5
And now solve.
4 X 1 + 5 = 9
So, now we know that our answer is fully correct.

How do you find percentages?
Answer:
obtained number divided by total number multiply by 100%.
· Definition of Percentages
Mathematically, percentages are either numbers or ratios that are expressed as fractions of 100. They are usually denoted as "%" or simply "percent." They may be further represented as simple fractions or as decimal fractions. An example of a percentage is 65% or 65 percent. The term percentage was formed from two words, “per” and “cent.” Cent is a word with Latin and French origin that means "hundred," and "percent" means "per hundred." For example, 90 percent (or 90%) means 90 out of 100 while 50 percent (or 50%) means 50 out of 100 or half of a whole.
1. Determine the initial format of the number to be converted to a percentage
The number to be converted to a percentage can either be in the decimal or fraction format. A good example of a decimal number is 0.57, which may be the calculated ratio of the values you are comparing, while an example of a fraction is 3/20. The initial format will determine the next mathematical process to be carried out on the number.
2. Carry out a mathematical process on the number to be converted to a percentage
If the number to be converted to a percentage is a decimal number like 0.57, you may not need to do anything to it before you go to the next step. However, if it is a fraction like 3/20, you should first divide the numerator (3 in this case) by the denominator (20 in this case) to get a decimal number.
3. Multiply the result of the mathematical process by 100
If you are required to convert a decimal number like 0.57 to a percentage, you are to simply multiply it by 100. That is, 0.57 x 100 = 57. Therefore, 0.57 as a percentage = 57% or 57 percent. Another example of converting a decimal to a percentage is 0.03 x 100 = 3% or 3 percent.
However, if you are required to convert 3/20 to a percentage, you should divide 3 by 20 = 0.15. Then multiply 0.15 by 100 = 15% or 15 percent.
Another example is if you are to convert 5/10 to a percentage, you should divide 5 by 10 = 0.5. Then, multiply 0.5 by 100. Therefore, 0.5 x 100 = 50% or 50 percent.

Decide if the following statement is true or false. A simple random sample of twelve 2+ bedroom houses in Rockingham County has a mean monthly lease of $695 with a standard deviation of $135. The true rental cost will be from $560 to $830
Answer:
Step-by-step explanation:
783
The given statement is "False" because the statement's range is based on the mean and standard deviation of a simple random sample of houses, not the whole population of Rockingham County's houses..
What is a simple random sample?A simple random sample is a subset of a population chosen in a way that gives each member of the population an equal chance of being selected. The mean and standard deviation of a simple random sample provides information about the population from which the sample was drawn, but they do not provide a range in which the true value of a population parameter is guaranteed to fall.
In this case, the statement provides a range for the true rental cost of 2+ bedroom houses in Rockingham County, but there is no guarantee that the true rental cost will fall within this range. The range provided in the statement is based on the mean and standard deviation of a simple random sample of houses, not the entire population of houses in Rockingham County.
Hence, the given statement is False.

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Billy read an average of 2.5 magazines each week during the year.
The equation that represents the number of magazines that he read (y) per week (x) will be

The points (6, 9) and (5, 8) fall on a particular line. What is its equation in slope-intercept form?
Answer:
y=x+3
Step-by-step explanation:
Start with the slope equation [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Since the first point is actually further along the x-axis that x-value becomes [tex]x_{2}[/tex] and its corresponding y-value is [tex]y_{2}[/tex]
[tex]\frac{9-8}{6-5}[/tex]=[tex]\frac{1}{1}[/tex]
The slope for the equation is just one so now find the y-intercept by rearranging the slope-intercept equation.
y=mx+b
y-mx=b
Now Substitute either point in to find b
9-1(6)=b
9-6=b
b=3
Your y-intercept is 3 so now we can write the slope-intercept equation for the two points:
y=x+3
In recent year, the total receipts for the US federal government were $2154 billion. The total outlays were $2472 billion. The deficit was $318 billion. What would the deficit have been, if there had been a 2% decrease in total receipts
If there had been a 2% decrease in total receipts, the new deficit would be $361.08 billion.
If there had been a 2% decrease in total receipts, the new total receipts would be:
New total receipts = $2154 billion - (2% of $2154 billion)
New total receipts = $2154 billion - $43.08 billion
New total receipts = $2110.92 billion
The total outlays would remain the same at $2472 billion.
So, the new deficit would be:
New deficit = New total outlays - New total receipts
New deficit = $2472 billion - $2110.92 billion
New deficit = $361.08 billion
Therefore, if there had been a 2% decrease in total receipts, the new deficit would be $361.08 billion.

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.
Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
2x + 3y = 1470
3y = -2x + 1470
y = -2/3x + 490 is the equation in slope intercept form.
slope = -2/3
y intercept = 490

The probability of event J, followed by event C is occurred is P( J | C)
What is probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
Experiment: A trial or procedure carried out to generate a result is referred to as an experiment.Sample Space: A sample space is the collection of all potential results of an experiment. Tossing a coin, for instance, has two possible outcomes: head or tail.Favorable Consequence: An occurrence is deemed to have generated the desired outcome or an anticipated event if it did so.Trial: To conduct a trial is to conduct a random experiment.The given case is case of Conditional Probability.
