The value of f(x) * g(x) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3
We have two functions -
f(x) = 4x + 8
g(x) = x + 3
We have to determine f(x)*g(x).
What is function in mathematics ?A function in mathematics is an expression with a independent variable (x) in it. The variable is called independent because it is not dependent on any value to get its value. Function also has a dependent variable (y) whose value depend on x. Ex -
y = f(x) = ax + d
According to the question, we have -
f(x) = 4x + 8
g(x) = x + 3
Therefore -
f(x) * g(x) = (4x + 8)(x + 3) = 4x(x + 3) + 8(x + 3) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3
Hence, the value of f(x) * g(x) = 4[tex]x^{2}[/tex] + 20[tex]x[/tex] + 3

9. Ms. Ortiz sells tomatoes wholesale. The function p(x)=–80x2 + 320x – 10, graphed below,
indicates how much profit she makes on a load of tomatoes if she sells them for 4- x dollars
per kilogram
What should Ms.Ortiz charge per kilogram of tomatoes to make the maximum profit, and what is the maximum profit she can make on a loaf of tomatoes
A. $230 at $3 per kilogram
B. $310 at $2 per kilogram
C. $320 at $2 per kilogram
D. $320 at $3 per kilogram
Answer:
The correct answer is B. $310 at $2 per kilogram
Step-by-step explanation:
1. Let's find out the maximum profit Ms. Ortiz can make with a loaf of tomatoes:
function p(x)=–80x² + 320x – 10
For x = 1, price per kilogram of tomatoes would be: 4 - x = 3
–80x² + 320x – 10, replacing with x = 1
-80 * 1² + 320 * 1 - 10 = -80 + 320 - 10 = 230
For x = 2 price per kilogram of tomatoes would be: 4 - x = 2
–80x² + 320x – 10, replacing with x = 2
-80 * 2² + 320 * 2 - 10 = -320 + 640 - 10 = 310
For x = 3, price per kilogram of tomatoes would be: 4 - x = 1
–80x² + 320x – 10, replacing with x = 3
-80 * 3² + 320 * 3 - 10 = -720 + 960 - 10 = 230
The correct answer is B. $310 at $2 per kilogram
Answer:The correct answer is B.) $310 at $2 per kilogram

daniel bought hamburgers and fries for his classmates. the hamburgers costed 1.49 each and a bag of fries cost 1.19. ben spent a total of 50.93. the number of hamburgers was five less than twice the amount of fries, how many hamburgers and fries did he buy
Number of hamburgers bought is 23 and number of bags of fries bought is 14
Solution:Let "h" be the number of hamburgers bought
Let "f" be the number of bags of fries bought
Cost of one hamburger = $ 1.49
Cost of one bag of fries = $ 1.19
Given that Ben spent a total of 50.93
Thus we can frame a equation as:
number of hamburgers bought x Cost of one hamburger + number of bags of fries bought x Cost of one bag of fries = $ 50.93
[tex]h \times 1.49 + f \times 1.19 = 50.93[/tex]
1.49h + 1.19f = 50.93 ------ eqn 1
Also given that the number of hamburgers was five less than twice the amount of fries
number of hamburgers bought = 2(number of fries) - 5
h = 2f - 5 ---------- eqn 2
Let us solve eqn 1 and eqn 2 to find values of "h" and "f"
Substitute eqn 2 in eqn 1
1.49(2f - 5) + 1.19f = 50.93
2.98f - 7.45 + 1.19f = 50.93
4.17f = 50.93 + 7.45
4.17f = 58.38
[tex]f = \frac{58.38}{4.17}[/tex]
f = 14Substitute f = 14 in eqn 2
h = 2(14) - 5
h = 28 - 5 = 23
h = 23Summarizing the results:
number of hamburgers bought = h = 23
number of bags of fries bought = f = 14

To make 5 batches of cookies, 10 cups of flour are required. Consider the question: How many cups of flour does each batch require? Please also work out the problem.
Answer:
2 cups of flour
Step-by-step explanation:
To make 5 batches of cookies, 10 cups of flour are required.
To make 1 batch of cookies:
10 cups ÷ 5 cups = 2 cups of flour.
To find out how many cups of flour are required for each batch of cookies, divide the total cups of flour (10 cups) by the number of batches (5 batches), which equals 2 cups of flour per batch.
Explanation:To determine how many cups of flour are needed for each batch, we can set up a simple division equation where we divide the total amount of flour by the number of batches. The student is given that 10 cups of flour make 5 batches of cookies. Using this information, we calculate the amount of flour per batch as follows:
Amount of flour per batch = Total cups of flour ÷ Number of batches
Amount of flour per batch = 10 cups ÷ 5 batches
Thus, the amount of flour required for each batch is:
Amount of flour per batch = 2 cups
Jack is two weeks into his diet and now weighs 197 pounds. If he lost 3 pounds the first week and 6 pounds the second week, what was his starting weight?
Answer:
206
Step-by-step explanation:
197 + 3 + 6 = 206
To find Jack's starting weight before he started his diet, we need to add the pounds he lost in the first and the second week back to his current weight.
Jack's current weight is 197 pounds.
In the first week, he lost 3 pounds.
In the second week, he lost 6 pounds.
So the total weight lost over the two weeks is 3 pounds + 6 pounds = 9 pounds.
Now we just add these 9 pounds back to Jack's current weight to find his starting weight before the diet.
197 pounds (current weight) + 9 pounds (total weight lost) = 206 pounds.
Thus, Jack's starting weight was 206 pounds.
While in Europe, if you drive 117 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 42.0 mi/gal ? Assume that 1euro=1.26dollars.
Answer:
Total Cost of Week = 81.20 Euros
Total Cost of Week (in dollars) = $102.31
Step-by-step explanation:
117 km per day
You drive 7 days
So,
Total miles driven = 117 * 7 = 819 km
Mileage is 42 miles per gallon. So how many gallons would it require to drive 819 km?
819/42 = 19.5 gallons
We know 1 gallons = 3.78 liters
So,
19.5 gallons would be:
19.5 * 3.78 = 73.82 liters
1.10 Euro PER LITER, so the total cost:
Total Cost of Week = 73.82 * 1.10 = 81.20 Euros
In dollars (1 euro = 1.26 dollars):
Total Cost of Week (in dollars) = 81.20 * 1.26 = $102.31
The cost on gas is approximately 7.2 euros
Data given;
Distance = 117kmrate of consumption = 42.0 mi/galcost of gas = 1.10 eurosConversion of distance from km to milesIf 1mi = 1.609km
And we cover 117km daily, let's convert this into miles
[tex]1mi=1.62km\\ x mi = 117km\\ x = 117/1.62\\ x = 72.2mi[/tex]
This shows that we cover a distance of 72.2 miles daily.
But the car consumes 1 gallon in 42 miles, let's calculate the gas required to cover 72.2 miles
[tex]42mi = 1g\\ 72.2mi =x\\ x = 72.2/42\\ x = 1.719[/tex]
The total gas consumed daily is approximately 1.72 gallons.
Cost of gas dailyThe cost of gas daily can be calculated from the data given but we have to convert the volume from gallon to liter
Gallon - Liter1L = 0.26 gallon
xL = 1.72 gallons
cross multiply this and solve for x
[tex]x = \frac{1*1.72}{0.26}\\ x = 6.6[/tex]
This shows that we consume 6.6L daily.
But we were given that the cost of 1 liter of gas is equal to 1.10 euros
1L = 1.10 euros
6.6L = x euros
[tex]x = \frac{1.1*6.6}{1}\\ x = 7.26[/tex]
The cost of gas daily is 7.26 euros or approximately 7.2 euros.

A student is trying to solve the system of two equations given below:
Equation P: y + z = 6
Equation Q: 3y + 4z = 1
Which of the following is a possible step used in eliminating the y-term?
(y + z = 6) ⋅ 4
(3y + 4z = 1) ⋅ 4
(y + z = 6) ⋅ −3
(3y + 4z = 1) ⋅ 3
Answer:
(y+z=6)*-3
Step-by-step explanation:
using this would make the top equation or (y+z=6) turn negative and would be this [-3y-3z=-18) using the distributive property. Since the bottom equation has a positive 3y. The -3y from the top equation and 3y from the bottom ones cancel out leaving you with z=-17 when combining like terms.
Answer:
c is the answer since you are trying to make the ys number (-/+) of the value the other y contains
(3) so you will multiply the first equation by -3 to be able to eliminate y
2. Juanita is trying to find the roots for the quadratic function f(x) = x2 + 64. She argues that there is no solution. Is Juanita correct? Justify your answer.
Answer:
Yes, Juanita is correct.
Step-by-step explanation:
Given:
The function given is:
[tex]f(x)=x^2+64[/tex]
The roots of a function means the values of 'x' for which the function intersects or touches the x-axis. Therefore, the roots are nothing but the x-intercepts of the function.
In order to find the roots of the above function, we should equate it to 0.
So, [tex]f(x)=0[/tex]
[tex]x^2+64=0\\\\x^2=-64[/tex]
We know that, square of any number is always a positive quantity. But here, the square of 'x' is -64 which is a negative number. This is not possible.
So, there is no real solution to the given function. In other words, we can say that the function doesn't intersect the x-axis.
Therefore, Juanita is correct in her argument.

Select the correct answer. If f(x) = |x| - 4, which translation is applied fo f(x) to get g(x)?
Answer:
It is a vertical translation of f(x) four units downward.
Step-by-step explanation:
We are given the original equation f(x) = |x| and the transformed function is g(x) = |x| - 4.
It is clear that the transformed function that g(x) = f(x) - 4.
So, the y-value in g(x) is reduced by 4 units from the y-value of f(x) i.e. the transformation is by 4 units down of function f(x).
Therefore, it is a vertical translation of f(x) four units downward. (Answer)
7x + 2y = 17
(3x +2y = 3)
Step-by-step explanation:
Multiply second equation by -1
-1 × (3x + 2y) = 3
-3x -3y = -3 now add this to the first equation
7x +2y = 17
(-3x-2y)= -3
7x +2y -3x -2y = 17 -3 (2y will eliminate -2y)
4x = 14
x = 7/2 now by using this information we found we can calculate the value for y
if 3x + 2y = 3 (replace x by 7/2)
3 ×(7/2)+2y = 3 ➡ 21/3 + 2y = 3 ➡ 2y = 3 - 21/3 ➡ 2ty = 15/2 ➡ y = 15/4

Q1. Ned washes dishes at a constant rate. Ned can hand-wash 18 dirty dishes in 3 minutes. Choose the graph that best represents the number of dishes, d, Ned can wash in any number of minutes, t.
(CHECK Media (picture) for answer choices)
Answer:
Graph A
Step-by-step explanation:
As we know, in 3 minutes he washes 18 dishes. Without even doing any math, you can see that this is the only graph that represents that. The others show that he washes two dishes in 12 minutes, which doesn’t make sense.
Ned's rate of washing dishes is 6 dishes per minute. The graph representing the number of dishes Ned can wash in any number of minutes would be an upward sloping line originating from the origin. The slope of this line, or the rate of change, signifies Ned's dish-washing rate.
Explanation:This is a typical problem in Mathematics subject related to speed or rate, specifically, it involves a rate of washing dishes. Ned can hand-wash 18 dishes in 3 minutes. Thus, Ned's rate of washing is 18 dishes per 3 minutes, or 6 dishes per minute.
The relationship between the dishes and the minutes is a direct proportional relationship since the amount of dishes Ned can hand-wash increases directly as the time increases.
To reflect this in a graph, we would have a straight, upward sloping line originating from the graph's origin (0,0). The slope of this line, or the rate of change, signifies the rate at which Ned can wash dishes.
Given that Ned can wash 6 dishes per minute, each point on the line should increase by 6 dishes for each increment of 1 minute on the time axis. Hence the correct graph would be a straight line with a slope of 6.

the NACI cafeteria wants to sell two 25 cm diameter medium size pizzas for the same price as one large pizza. what should the diameter be of the large pizza so that it contains the same amount of pizza as the two medium-size pizzas?
Answer:
35.34 centimeters
Step-by-step explanation:
The amount of pizza is same as the area. The pizza is in a shape of a circle. The area of a circle is:
[tex]A=\pi r^2[/tex]
Where
r is the radius (half of diameter)
Area of one medium size pizza is (diameter 25 means radius is 25/2 = 12.5):
[tex]A=\pi r^2\\A=\pi (12.5)^2\\A=490.87[/tex]
So, area of two of these medium size pizzas is:
490.87 * 2 = 981.74
This should be the area of the large pizza. We can find the radius of that by substituting into formula. Shown below:
[tex]A=\pi r^2\\981.75=\pi r^2\\r=\sqrt{\frac{981.74}{\pi}} \\r=17.67[/tex]
Hence, the diameter would be around:
