Answer:
Answer:
Solution given:
f(x)=5x-3
let
y=f(x)
y=5x-3
interchanging role of x and y
x=5y-3
x+3=5y
y=
$o,
f-¹(x)=
we conclude that
f-¹(x)≠g(x)
Each pair of function are not inverses.
g(x)=x/5+3
let g(x)=y
y=x/5+3
interchanging role of x and y
x=y/5+3
x-3=y/5
doing crisscrossed multiplication
5(x-3)=y
y=5x-15
g-¹(x)=5x-15
So
g-¹(x)≠f-¹(x)
Each pair of function are not inverses.
Answer:
11x
Step-by-step explanation:
you add the numbers like you normally would and then add the x at the end
3 + 6 + 2 = 11
add the x
11x
Answer:400
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
We can start by subtracting 3 from both sides of the equation:
7(x+2) + 3 - 3 = 73 - 3
We will get:
7(x+2) = 70
Now we have to figure out what times seven gives us 70:
70/7 = 10
We get the answer 10. Now we know that:
x+2 = 10
We can now subtract two from both sides of the equation:
x+2-2 = 10-2
We will get:
x = 8
Answer:
240 cars
Step-by-step explanation:
The salesman sells 15 to 25 cars per month. Average number of cars sold per month would be = cars per month
one year has 12 months
Number of cars sold in an year = monthly rate x no. of months
= 20 x 12
= 240 cars
