If f(3) = 12, which of the following could be a solution for the equation f(x).
Answers
Answer
f(x) = 3x+3
Explanation
So basically your replacing x with 3 to see which one would turn out to be 12.
3(3) = 9
2(3)+12 = 18
3(3)+3 = 12
(3)+10 = 13
Only the third one becomes 12 when you replace x with 3, so the answer is number 3.
The function of which f(3) = 12 is the solution is f(x) = 3x + 3 thus option (C) will be correct.
What is a function?The function is a relationship between variables, and the nature of the relationship defines the function for example y = six and y = x +6 like that.
Given the solution of an unknown function,
f(3) = 12
If it is the solution then it must satisfy the respective function.
By cross-checking options ;
Option (A) →
f(3) = 3×3 = 9 so it will not the function.
Option (B) →
f(3) = 2(3) + 12 = 18 so it will not the function.
Option (C) →
f(3) = 3(3) + 3 = 12 so it will be the respective function.
Hence "The function of which f(3) = 12 is the solution is f(x) = 3x + 3".

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is to determine the product of two or more numbers. If an event can occur in m different ways and if following it, that a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We don not write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together.
We are given the number as 9 x 3
WE can see that the number is multiple of 3
Therefore by using simplification we get;9 x 3 = 27
Hence, the answer is 27.

Juan and Ari went to the farmers market to buy fruit. Juan’s bag of apples that he bought weighed 31/7 pounds. Ari’s bag of oranges that she bought weighed 19/3 pounds. Using compatible fractions, estimate how much heavier Ari's bag is compared to Juan's bag.
A) 1 and one-half pounds
B) 2 pounds
C) 6 pounds
D) 10 and one-half pounds
Answer:
B: approximately 2 pounds
Step-by-step explanation:
Juan’s bag weighed 31/7 pounds
Ari's bag weighed 19/3 pounds.
We are told to use compatible fractions to determine the difference. Thus we have to make sure the denominator is the same;
For Juan, let's multiply both numerator and denominator by 3 to get; 93/21 pounds
For Ari, let's multiply both numerator and denominator by 7 to get; 133/21
Thus, difference is;
(133/21) - (93/21) = 40/21
This gives;
1.9 pounds heavier
This is approximately 2 pounds

B. 2 pounds

and no boxes were removed, all the boxes in the warehouse were arranged in stacks of 14 boxes each, with no boxes left over. How many boxes were in the warehouse before the 60 additional boxes arrived
Answers
Answer:
360 boxes
Step-by-step explanation:
The number of boxes in the warehouse before 60 boxes were added is;
n = 12k .... equation 1
where k is the constant of the number of stacks and n is the number of boxes.
The number of boxes after the 60 boxes were added is;
n + 60 = 14k ... equation 2
substitute the value of n in equation 2 for equation 1:
12k + 60 = 14k
60 = 14k - 12k
60 = 2k
k = 60 / 2 = 30
The number of boxes in the warehouse before 60 boxes was added is;
n = 12 * 30 = 360
Including Jose, there are eight people in his family. If order matters, how many ways can he arrange his family members into a row of five seats if Jose must sit in the first seat?
Answers
Answer:
840 ways
Step-by-step explanation:
From the above question, we are told that order matters, hence, to solve the above question, we use the Permutation formula.
P(n, r) = nPr = n!/(n -r)!
From the above question,
Since Jose is included in the 8 people and he takes the first seat
n = 8 - 1 = 7 people
r = 5 - 1 = 4 seats
This is because, once Jose takes the first seat, there are 4 seats left with 7 people waiting to be seated
Hence,
7P4 = 7!/(7 - 4)!
7P4 = 7!/3!
7P4 = 5040/6
7P4 = 840 ways

Answer:
Please check the explanation.
Step-by-step explanation:
Given the points
(x₁, y₁)(x₂, y₂)Using the formula to determine the slope between (x₁, y₁) and (x₂, y₂) of the linear function
Slope = m = [y₂ - y₁] / [x₂ - x₁]
For example, let the points be
(x₁, y₁) = (1, 2)
(x₂, y₂) = (3, 4)
Determining the slope between
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [3 - 1]
= 2 / 2
= 1
Thus,
The slope of the line between the points (1, 2) and (3, 4) will be: m = 1

The Kansas predicted that in 2018 the population in Centerville would be 17,466 and actuality it was 16,400 what is the percent error
Answers
Answer:
6.5%
Step-by-step explanation:
Percentage error formula =
|Estimated value - Real value|/Real value × 100
From the above question,
Estimated value = 17,466
Real value = 16,400
Percentage error = |17,466 - 16,400|/16,400 × 100
= 1066/16,400 × 100
= 0.065 × 100
= 6.5%
Therefore, the percent error = 6.5%
Answer: 6.5%
Step-by-step explanation: 17,466 - 16,400 = 1,066 (the difference)
16,400 / 16,400 = 1 • 100 = 100
1,066 / 16,400 = 0.065 • 100 = 6.5
