What is the inverse of the function h(x)=\dfrac{5}{2}x+4h(x)= 2 5 ​ x+4h, left parenthesis, x, right parenthesis, equals, start
Phantasy [73]

Answer:

The inverse of the function h(x) is h^{-1}(x)=\frac{2}{5}x-\frac{8}{5}.

Step-by-step explanation:

The given function is

h(x)=\dfrac{5}{2}x+4

Replace h(x) by y.

y=\dfrac{5}{2}x+4

Interchange x and y.

x=\dfrac{5}{2}y+4

Subtract 4 from both sides to isolate variable y,

x-4=\dfrac{5}{2}y

Multiply both sides by 2.

2x-8=5y

Divide both sides by 5.

\frac{2}{5}x-\frac{8}{5}=y

Replace y by h⁻¹(x).

h^{-1}(x)=\frac{2}{5}x-\frac{8}{5}

Therefore the inverse of the function h(x) is h^{-1}(x)=\frac{2}{5}x-\frac{8}{5}.

A farmer grows two types of grain in his fields. he has a seed budget of $20,000.00 and has spent $11,200.00 to plant wheat seed
Arisa [49]
For the answer to the question above, I'll provide a solution below.
52x < = 20,000 - 11200
52x < = 8800
x < = 8800/52
x < = 169.23
So the answer to your question is 169 acres <span>of barley the farmer can plant and still be under budget.
I hope my answer helped you. have a nice day!</span>
