General Formulas and Concepts:
Algebra I
Composite FunctionsCombining Like TermsStep-by-step explanation:
Step 1: Define
f(x) = x - 7
h(x) = 2x + 3
f(h(x)) is x = h(x)
Step 2: Find f(h(x))
Substitute: f(h(x)) = (2x + 3) - 7Combine like terms: f(h(x)) = 2x - 4Zelda rode her bike at a steady rate of 12 miles per hour for 3
Answer:
36miles
Step-by-step explanation:
Given parameters:
Rate = 12mph
Time = 3hr
Unknown:
Distance = ?
Solution:
The given rate amount is the speed. Speed is the distance divided by the time.
It is mathematically expressed as:
Speed = [tex]\frac{distance}{time}[/tex]
Distance = Speed x time
Distance = 12 x 3 = 36miles

Find f(g(4)) if f(x)=2x+1 and g(x)=x^2
Answer:
is this even math????
Step-by-step explanation:
First solve g(x) by replacing x with 4
G(x) = x^2 = 4^2 = 16
Now replace x in f(x) with 16:
F(x) = 2x + 1 = 2(16) + 1 = 32 +1 = 33
The answer is 33
Monica can clean the house in 5 hours by herself. When Monica and Sydney
work together, it takes 3 hours. How long would it take Sydney to clean the
house by herself?
A. 5.5 hours
B. 7.5 hours C. C: 2.0 hours
D. 4.7 hours
Answer:
The answer is B 7.5 hours.
Step-by-step explanation:
A. P. E. X
Sydney can clean her house in 7.5 hours.
What is Efficiency?Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output ("product") produced per the amount C ("cost") of resources consumed.
Here, Monica can clean her house in 5 hours
Monica's efficiency = 1/5
Let, Sydney cleans the house in x hours.
Sydney's efficiency = 1/x
They both together complete their work in 3 hours
Combined efficiency = 1/3
Now, according to question;
1/5 + 1/x = 1/3
(x+5)/5x = 1/3
3x + 15 = 5x
5x - 3x = 15
2x = 15
x = 15/2
x = 7.5
Thus, Sydney can clean her house in 7.5 hours.

Average Weekly Earnings The average weeklyearnings in dollars for various industries are listedbelow. Find the percentile rank of each value.
804 736 659 489 777 623 597 524 228
For the same data, what value corresponds to the 40th percentile
Answer:
a. 228- 6th, 489- 17th, 524- 28th, 597- 39th, 623- 50th, 659- 61th, 736- 72th, 777- 83th, 804- 94th
b. 597
Step-by-step explanation:
arrange the data:
228, 489, 524, 597, 623, 659, 736, 777, 804
a. percentile = ((number of items below position + 0.5)/ number of items ) 100
for 228 = (0+0.5/ 9) 100 = 6th
for 489 = (1+0.5/ 9) 100 = 17th
for 524 = (2+0.5/ 9) 100 = 28th
for 597 = (3+0.5/ 9) 100 = 39th
for 623 = (4+0.5/ 9) 100 = 50th
for 659 = (5+0.5/ 9) 100 = 61th
for 736 = (6+0.5/ 9) 100 = 72th
for 777 = (7+0.5/ 9) 100 = 83th
for 804 = (8+0.5/ 9) 100 = 94th
b. The corresponding value for the 40th = number of item( percentile)/ 100
= 9( 40) / 100 = 3.6 approximately 4th which is 597
