Step-by-step explanation:
The function composition is achieved by putting the second function in first function in place of independent variable.
Given functions are:
In order to find (fog)(x) we will put function g in function f in place of x
Since we have to find (fog)(7)
Putting 7 in place of x
Hence,

Answer:
3"x4
Step-by-step explanation:
The symbol for a foot is "ft", sometimes denoted by a prime(') , also, the inch is denoted by a double prime(").
Given
2 1/2inces (2.5") blue print represents 10ft living room
We are told that the dimension of the room on the blueprint is
12'x16'
Let us convert 12' to inches
So
2.5" represents 10'
X ' will be 12'
Cross multiplying
X=(2.5*12)/10
X=3"
Let us convert 16' to inches
So
2.5" represents 10'
Y ' will be 16'
Cross multiplying
Y=(2.5*16)/10
Y=4"
the dimension of the blue print is
3"x4"
Answer:
f(4) = (4)² + 5(4) = 36.
g(9) = [3(9) - 4]/2 = 23/2.
f(-3) = (-3)² + 5(-3) = -6.
g(-6) = [3(-6) - 4]/2 = -11.
Set f(x) = 14.
=> x² + 5x = 14
=> x² + 5x - 14 = 0
=> (x + 7)(x - 2) = 0
=> x = -7 or x = 2.
Set g(x) = -28.
=> (3x - 4)/2 = -28
=> 3x - 4 = -56
=> 3x = -52
=> x = -52/3.
Answer:
36
11.5
6
-11
-2, 7
-17.333 / - 17⅓
Step-by-step explanation:
f(4) = 4² + 5(4) = 16+20 = 36
g(9) = 3(9)-4 ÷ 2 = 23÷2 = 11.5
f(-3) = (-3)²+5(-3) = 9 - 15 = 6
g(-6) = 3(-6)-4 ÷ 2 = - 22 ÷ 2 = - 11
f(x) = 14
x² - 5x = 14
x² - 5x - 14 = 0
(x+2) (x-7) = 0
x = - 2 or x = 7
g(x) = -28
3x - 4 = - 56
3x = - 52
x = - 52/3 = - 17 ⅓

The true statement about the juan and lisa is Juan made a higher rate of pay than Lisa.
Juan made a lower rate of pay because he made less money.
This statement is false. Juan and Lisa made a similar rate of pay per hour ($14.80 and $14.00 respectively).
Lisa made a better rate of pay because she made more money.
This statement is false. The total earnings do not determine the rate of pay; the hourly rate does.
Lisa said she made a better rate of pay because her rate was $14 an hour.
This statement is false. Lisa's actual rate was $14.00 per hour, not $14.00 as stated.
Juan said he made a better rate of pay because he was paid $14.80 an hour.
This statement is true. Juan's hourly rate was $14.80, which is higher than Lisa's rate of $14.00 per hour.
To calculate the rate of pay, we divide the money earned by the hours worked.
Juan's rate of pay is $37.00 / 2.5 hours = $14.80 per hour.
Lisa's rate of pay is $42.00 / 3 hours = $14.00 per hour.
Therefore, Juan made a higher rate of pay than Lisa.
Answer: Juan said he made a better rate of pay because he was paid $14.80 an hour.
