Can someone help with math?
algol [13]

Answer:

A. {4,3}

Step-by-step explanation:

x -2y = -2

    y = - 3x +15

x - 2(-3x+15) = -2

x +6x - 30 = -2

7x = 28

x = 4

y = - 3x +15 = - 3*4 + 15 = -12 + 15 = 3

If f(x) = 6x + 3, find −1 ().
lianna [129]

Answer:

f^{-1}(x)=(1/6)x-(1/2)

Step-by-step explanation:

we have

f(x)=6x+3

Find the inverse function f^{-1}(x)

step 1

Let

y=f(x)

y=6x+3

step 2

Exchanges variables, x for y and y for x

x=6y+3

step 3

isolate the variable y

x=6y+3

6y=x-3

y=(1/6)x-(1/2)

step 4

Let

f^{-1}(x)=y

f^{-1}(x)=(1/6)x-(1/2)
