Answer:

Step-by-step explanation:

x + y = 5

y = 3x + 1

x + 3x + 1 = 5

4x + 1 = 5

4x = 4

x = 1

1 + y = 5

y = 4

(1, 4)

Answer:

One pair of socks is $370.

Step-by-step explanation:

Sean bought <em>three pairs</em> of the same socks and a shoe polish for $1450. If the

polish cost $340, how much is the cost of <em>one pair</em> of socks.

6x - 340 = 1450

6x = 1450 -340

6x = 1110

2x = 1110 / 3

2x = 370

What is the inverse of f(x)=−3x+5?
kotykmax [81]

Answer:

f-¹(x) = (4- x)/ 3

Step-by-step explanation:

inverse of a function is nothing but the value of x in terms of f(x)

like

if we write f(x) as y we'd get

y = - 3x + 5

so, ill express x in terms of y:-

y= -3x + 4

  • adding 3x on both sides of the equation

y + 3x = -3x + 3x + 4

  • subtracting y on both sides

y - y + 3x = 4 - y

3x = 4 - y

  • dividing the whole equation by 3

x = (4 - y)/ 3

soo, the inverse of the function is x = (4- y)/ 3

mostly we write the inverse in terms of x, hey! don't get confused, when i say this, I simply mean that we're gonna replace y with x and x with f-¹(x).

therefore,

f-¹(x) = (4- x)/ 3
