If f (x) = 8 (5x - 2) find f (x)​

Mathematics
1 answer:
Pepsi [2]2 years ago
8 0

Answer:

f-1(x) = (x - 16)/40

B

Step-by-step explanation:

Call f(x) = y

Interchange x and y

x = (5y + 2)*8             Remove the brackets

x = 40y + 16               Subtract 16 from both sides

x - 16 = 40y                Interchange the left and right sides

40y = x - 16                Divide by 40

y = (x - 16)/40

f-1(x) = (x - 16)/40

Mekhanik [1.2K]

Answer:

y = 1/2x + 3

O f(x)= 1/2x+3

Step-by-step explanation:

f(x) = 2x - 6

y = 2x - 6

x = 2y - 6

2y = x + 6

y = (x + 6)/2

y = 1/2x + 3

Solve the following system of equations using a method of your choice.
dusya [7]

Answer:

Step-by-step explanation:

cant remember what this method is called but

change the second equation to be y = something

x + y = 10

y = -x + 10

plug in this y= in the first equation to get x

4x -2(-x + 10) = 4

4x + 2x -20 = 4

6x = 24

x = 4

then plug in the x we found into the original second equation

4 + y = 10

y = 6

so your ordered pair would be (4,6)

hope this helps <3
