=============================================
Work Shown:
f(x) = x+4
y = x+4 ..... since y = f(x)
y = 3p+4 .... replace x with 3p, because x = 3p
(x,y) = (3p, y) .... replace x with 3p
(x,y) = (3p, 3p+4) ... replace y with 3p+4
Answer:
D
Step-by-step explanation:
In an ordered pair, the input is the first value, and the output is the second value.
The input, x, in this case equals 3p, so that will be our first value, which eliminates answers A and B.
Now to find the output, simply plug the input into all instances of x in the equation, like so:
[tex]f(3p) = (3p) + 4 [/tex]
Resolving that, we get 3p + 4 as our second value, which combined with our first value gets us (3p, 3p+4), which is answer D.
The table and statement show the hours worked and the amounts paid for two workers.
A table labeled Worker A Earnings. It contains a row for Hours worked with the amounts 7, 12, 21, 33, 40, and a row for Amount paid with the amounts 87.50, 150, 262.50, 412.50, and 500.
Worker B earns $11.25 per hour
Which statements about the rates of pay for the two workers are true?
Select each correct answer.
Worker A earns less per hour than Worker B.
Worker B earns more after 10 hours than worker A.
Worker A earns $12.50 per hour.
After 20 hours of work, Worker A earns more than Worker B.
1st statement is correct
2nd statement is correct.
finding the average hours worker A does and then the average amount paid i got
average hrs = 22.6 hrs and average amount paid= $250
so comparing them to one hr i got the amount paid to worker A in one hr which is $1.11
so compare to worker B earnings and find the true statements

Which recursive formula can be used to determine the total amount of money earned in any year based on the amount earned in the previous year?
f(n + 1) = f(n) + 5
f(n + 1) = 5f(n)
f(n + 1) = 1.05f(n)
f(n + 1) = 0.05f(n)
Answer:
f(n + 1) = 1.05f(n)
Step-by-step explanation:
The total amount of money earned in any year based on the amount earned in the previous year is f(n+1) = 1.05f(n).
What is annual interest rate?The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned.
What is principal?Principal is the money that you originally agreed to pay back. Interest is the cost of borrowing the principal.
According to the question,
The annual interest rate is 5%
So, suppose the amount earned in the previous year is f(n).
The total amount of money earned in any year based on the amount earned in the previous year is
f(n+1) = f(n) + 5%f(n) (principal + interest)
f(n+1) = 1.05f(n)
Hence, the total amount of money earned in any year based on the amount earned in the previous year is f(n+1) = 1.05f(n).

how do I solve this and the answer is NOT x<8 the answer is supposed to be x<1 but I don't know how to get there.
8(k - 6) +58 = 2(4k + 5)
one solution
no solutions
infinite solutions
Answer:
infinite solutions
Step-by-step explanation:
Given
8(k - 6) + 58 = 2(4k + 5) ← distribute parenthesis on both sides
8k - 48 + 58 = 8k + 10 , that is
8k + 10 = 8k + 10
Since both sides are equal then any value of x will make the equation true.
There are an infinite number of solutions

D. Yes; SSS; ΔLFT ∼ ΔORT
Answer: They are not similar
Step-by-step explanation: Only way is AAA and AAA doesn’t prove triangles congruent or similar
Option (C) impossible to determine is the correct answer.
What is triangle similarity?Two triangles are said to be similar, if corresponding sides of the two triangles has same ratio or the corresponding angles of the two triangles are equal.
For the given situation,
The diagram has two triangles but the length of the sides and the angles of the triangles are not provided. So we cannot find the similarity between these two triangles.

determine if the equation y=2/7x represents a direct variation
Answer:
Represents a direct variation
Step-by-step explanation:
y = 2/7x
To find x-intercept/zero, substitute
y = 0
0 = 2/7x
Multiply both sides of the equation by 7/2
0 = x
Swap the sides of the equation
x = 0
Solution
x = 0
This is a direct variation because when x = 0. Y has to = 0 as well and it is so that makes this equation a direct variation.
direct variation - mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other
