Answer:
(f + g) (x) = 5x - 11
(f - g) (x) = x + 3
Step-by-step explanation:
f(x) = 3x - 7
g(x) = 2x - 4
to find ; (f + g) (x) and (f - g) (x)
now,
(f + g ) (x) = f (x) + g(x)
= (3x - 7) +( 2x - 4 )
= 3x - 7 + 2x - 4
= 5x - 11
again ,
(f - g ) (x) = f(x) - g(x)
= (3x - 7) - (2x - 4)
= 3x - 7 - 2x + 4
= x + 3
The gross profit is $72.45
The percentage profit is 82.8%
Step-by-step explanation:
The profit is the earning on selling a product or item in price more than its purchasing price.
Given
Purchase price of Lawn mower = $87.50
Sale price = $159.95
Profit = Sale Price - Purchase Price
=159.95-87.50
=72.45
The percentage profit is:
The gross profit is $72.45
The percentage profit is 82.8%

The total number of sample space in this item is calculated by adding up all the number of students given. That is,
S = 600 + 400 + 300 + 200 = 1500
The probability is calculated with the equation below.
P = n / S
where P is the probability,
n is the number of sophomores, and
S is the total number of students
Substituting,
P = 400 / 1500 = 4/15
<em>ANSWER: 4/15</em>
Answer: 4
Step-by-step explanation:
( f o g ) (3) means f(g(3)) so...
First: plug 3 into g(x) = x^ (2-1)
3^ (2-1) is 3^1 = 3
Next: plug 3 into f(x)= 2^(x-1)
2^(3-1) is 2^(2) > 2×2 = 4
