Is the following relation a function?
Need answer now
If you can draw a vertical line through more than one point on the curve, then it's not a function. In this case, we can draw such a line. The graph is said to have failed the vertical line test.
What this means is that some x inputs lead to more than one y outputs. A function is only possible if any x input leads to exactly one y output. The x input must be in the domain.
Answer:
It is not a function.
Step-by-step explanation:
A relation's inputs are not repeated in a function.
Since the graph fails the vertical line test, it is not a function.
See picture.
Hope this helps.

Bernardo is converting a fraction, StartFraction a Over b EndFraction, to a percent. Both a and b are whole numbers and not equal to zero. Which expression represents the percent?
Answer:
[tex]Percent = \frac{100a}{b}\%[/tex]
Step-by-step explanation:
Given
[tex]\frac{a}{b}[/tex]
Required
Convert to fraction
To do this, we simply multiply the fraction by 100%
This gives:
[tex]Percent = \frac{a}{b} * 100\%[/tex]
[tex]Percent = \frac{a * 100}{b}\%[/tex]
[tex]Percent = \frac{100a}{b}\%[/tex]
The expression cannot be further simplified.
Take for instance the fraction is: [tex]\frac{2}{5}[/tex]
Using the same analysis, the percentage would be:
[tex]Percent = \frac{2}{5} * 100\%[/tex]
[tex]Percent = \frac{2 * 100}{5}\%[/tex]
[tex]Percent = \frac{200}{5}\%[/tex]
[tex]Percent = 40\%[/tex]
Answer:
100(a divided by b)

Given data:
Cars Vans Others
60 21 3
The data represents the number of cars on a single day.
Find the relative frequency;
It is the number of times an event occurs.
Here the time frame is within a day;
Relative frequency = [tex]\frac{number of cars + number of vans + others}{number of days}[/tex]
Relative frequency = 60 + 21 + 3 = 84vehicles per day
ii.
Number of vans in a week;
Number vans in a week = 21van per day x 7 days = 147vans

Answer:

Step-by-step explanation:
1. (x² - 4x - 10) + (x² - 9x + 3)
= x² - 4x - 10 + x² - 9x + 3
= x² + x² - 4x - 9x + 3 - 10
= 2x² - 13x - 74. (3x² - x + 1) + (15 - 9x - 2x²)
= 3x² - x + 1 + 15 - 9x - 2x²
= 3x² - 2x² - x - 9x + 1 + 15
= x² - 10x + 167. (6 - 2x + 7x²) - (10x - 3 + 3x²)
= 6 - 2x + 7x² - 10x + 3 - 3x²
= 7x² - 3x² - 2x - 10x + 6 + 3
= 4x² - 12x + 9120 caleriess in 2 servings 360 caleries in 6 servings
Answer:
60 calories per serving
Step-by-step explanation:
Divide to find the unit rate of calories per serving.
120 / 2 = 60
360 / 60 = 60

A florist charges $25 for a vase plus $4.50 for each flower. The total charge for the vase and flowers is given by the function f(x) = 4.50x + 25. How will the graph change if the vase’s cost is raised to $35? if the charge per flower is lowered to $3.00?
a) The graph change if the vase’s cost is raised to $35 is the line
[tex]y=4.5x+35[/tex]
b)The charge per flower is lowered to $3.00 is the line
[tex]y=3x+25[/tex]
We have given that the function
[tex]f(x) = 4.50x + 25[/tex]
A florist charges $25
Now we have given condition the cost is raised to 35$
We use we use the slope intercept form
What is the slope intercept form?
[tex]y=mx+C[/tex]
y is function f(x) C=vase cost, and m= charge per flower
Therefore we get,
[tex]y=f(x),m=4.50 and c=25[/tex]
we have given condition C=35$
So the line will just move up to have a y-intercept at (0,35) the equation will be,
[tex]y=4.5x+35[/tex]
Therefore,
The graph change if the vase’s cost is raised to $35 is the line
[tex]y=4.5x+35[/tex]
We have given that the charge per flower is lowered to 3$
So the slope
[tex]m=3[/tex]
Here the m value is being changed so your line will just flatten out a bit and the new equation will be
[tex]y=3x+25[/tex]
The charge per flower is lowered to $3.00 is the line
[tex]y=3x+25[/tex]

The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8500 ft, the liquid boils at 199.55 F. At an altitude of 4300 ft, the liquid boils at 206.69 F. Write an equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet. What is the boiling point of the liquid at ft?
Answer:b = -0.0013a + 211
Step-by-step explanation:
Since the relationship is linear, we can use a linear equation. The formula in slope-intercept form is .
As the question specifies to use a for altitude and b for boiling point, change the variables equation to
b is the boiling point.
m is the slope.
a is the altitude.
c is the y-intercept.
To find the slope, we can use the equation except x is a and y is b.
The sets of information given are:
8500 ft, the liquid boils at 199.95° (This can be info set 1)
4300 ft, the liquid boils at 205.41° (This can be info set 2)
Substitute the info sets into the equation. The subscripts mean which info set to get the numbers from.
m = -0.0013
Find the y-intercept by substituting m = -0.0013 and a random info set. I will use info set 1. Isolate c, the only variable.
b = ma + c
199.95 = (-0.0013)(8500) + c <= Simplify
199.95 = -11.05 + c
199.95 + 11.05 = -11.05 + 11.05 + c <=add 11.05 on both sides to isolate c
c = 211 <= y-intercept
Put the y-intercept and slope into the equation of a line:
b = ma + c
b = -0.0013a + 211 <= This is the equation for the problem.

2.Yolanda is buying supplies for school. She buys n packages of pels at $1.40 per package and m pads of paper at $1.20 each. What does each term in the expression 1.4n + 1.20m represent? What does the entire expression represent? Interpret the meaning of the term 1.4n. What does the coefficient 1.4 represent? Interpret the meaning of the term 1.20p. What does the coefficient 1.20 represent?
Answer: 1.4n represents the cost of n packages of pels.
1.20m represents cost of m pads.
Entire expression 1.4n + 1.20m represents total cost of n packages of pels and m pads.
Meaning of 1.4n = cost of n packages of pels.
Meaning of 1.20 m = represents cost of m pads.
where , 1.4 = Cost per package of pels
1.2 =Cost per pad of paper
Step-by-step explanation:
Given: Cost per package of pels = $1.40
Cost per pad of paper = $1.20
Number of packages of pels bought = n
Number of pads of paper bought = m
So, 1.4n represents the cost of n packages of pels.
1.20m represents cost of m pads.
Entire expression 1.4n + 1.20m represents total cost of n packages of pels and m pads.
Meaning of 1.4n = cost of n packages of pels.
Meaning of 1.20 m = represents cost of m pads.
where , 1.4 = Cost per package of pels
1.2 =Cost per pad of paper
