Answer:
f + g)(x) = f (x) + g(x)
= [3x + 2] + [4 – 5x]
= 3x + 2 + 4 – 5x
= 3x – 5x + 2 + 4
= –2x + 6
(f – g)(x) = f (x) – g(x)
= [3x + 2] – [4 – 5x]
= 3x + 2 – 4 + 5x
= 3x + 5x + 2 – 4
= 8x – 2
(f × g)(x) = [f (x)][g(x)]
= (3x + 2)(4 – 5x)
= 12x + 8 – 15x2 – 10x
= –15x2 + 2x + 8
\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(
g
f
)(x)=
g(x)
f(x)
= \small{\dfrac{3x+2}{4-5x}}=
4−5x
3x+2
My answer is the neat listing of each of my results, clearly labelled as to which is which.
( f + g ) (x) = –2x + 6
( f – g ) (x) = 8x – 2
( f × g ) (x) = –15x2 + 2x + 8
\mathbf{\color{purple}{ \left(\small{\dfrac{\mathit{f}}{\mathit{g}}}\right)(\mathit{x}) = \small{\dfrac{3\mathit{x} + 2}{4 - 5\mathit{x}}} }}

Answer:
B) 2 hours
Step-by-step explanation:
If machine A complete a job in 3 1/2 hours or 7/2 of an hour
means that in one hour finished 1÷ 7/2 or 2/7
If machine B complete a job in 4 2/3 hours or 14/3 of an hour
means that in one hour finished 1÷ 14/3 or 3/14 of an hour
Then the two machines working together in one hour will make
2/7 + 3/14 = (4 + 3)/ 14
or 7/14 = 1/2
half of the job. Therefore these two machines working together will take two hours
Answer:
The amount of the fee for the truck is $20 and cost per mile is $1.3.
Step-by-step explanation:
If they pay a fee x dollars for the truck and y dollars per mile they drive.
Carrie drives 150 miles and pays $215.
Her fee= $x for the truck + 150 X y =215
x+150y=215...(I)
Similarly, Dave drives 120 miles and pays $176
His fee =$x for the truck + 120 X y = 176
x+120y=176....(ii)
To determine the values of x and y, we solve Equations I and II simultaneously.
x+150y=215...(I)
x+120y=176....(ii)
Using elimination method (Subtracting equation II from I)
30y=39
y=1.3
Substitute y=1.3 into (I) to get x.
x+150y=215...(I)
x+(150X1.3)=215
x+195=215
x=215-195=20
Since x=20, y=1.3, The amount of the fee for the truck is $20 and cost per mile is $1.3.
