Find the inverse of the function: f(x)=1/5x+4
Greeley [361]

Answer:

B. {f}^{ - 1} (x) = 5x - 20

Step-by-step explanation:

f(x) =  \frac{1}{5} x + 4

y =  \frac{1}{5} x + 4

x =  \frac{1}{5} y + 4

\frac{1}{5} y + 4 = x

y + 20 = 5x

y = 5x - 20

\boxed{\green{{f}^{ - 1} (x) = 5x - 20}}

Solve the simulataneous equations. 5x-4y=19 x+2y=8
inysia [295]

Answer:

(5, 1.5 )

Step-by-step explanation:

Given the 2 equations

5x - 4y = 19 → (1)

x + 2y = 8 → (2)

Multiplying (2) by 2 and adding to (1) will eliminate the y- term

2x + 4y = 16 → (3)

Add (1) and (3) term by term to eliminate y

7x + 0 = 35

7x = 35 ( divide both sides by 7 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (2)

5 + 2y = 8 ( subtract 5 from both sides )

2y = 3 ( divide both sides by 2 )

y = 1.5

solution is (5, 1.5 )
