Answer:

\displaystyle h^{-1}(x) = 2\frac{1}{2}x - 3

Step-by-step explanation:

\displaystyle y = \frac{2x + 6}{5} → x = \frac{2y + 6}{5} \\ \\ 5x = 2y + 6

5x = 2y + 6

- 6 - 6

_________

\displaystyle \frac{-6 + 5x}{2} = \frac{2y}{2} \\ \\ -3 + 2\frac{1}{2}x = y → h^{-1}(x) = 2\frac{1}{2}x - 3

I am joyous to assist you anytime.

Answer:

h^{-1}(x) = \dfrac{5x - 6}{2}

Step-by-step explanation:

h(x)= \dfrac{2x + 6}{5}

(a) Rename h(x) as y  

y = \dfrac{ 2x+ 6}{5}

(b) Solve for x :  

\begin{array}{rcl}y& = &\dfrac{2x + 6}{5}\\\\5y & = & 2x + 6\\5y - 6 & = & 2x\\x & = & \mathbf{\dfrac{5y - 6}{2}}\end{array}

(d) Switch x and y  

y = \dfrac{5x -6}{2}

(e) Rename y as the inverse function  

h^{-1}(x) = \mathbf{\dfrac{5x - 6}{2}}

The graphs of inverse functions are reflections of each other across the line y = x.

In the diagram, the graph of h⁻¹(x) is the reflection of h(x) about the line y = x.

find 2 consecutive integers such that three times the square of the first is equal to seven more than five times the second
melamori03 [73]

Answer:

Step-by-step explanation:

We are looking for two numbers, N and N + 1. From the problem statement, we can setup the following equation:

3N^{2} = 5(N + 1) + 7

3N^{2} = 5N + 5 + 7

3N^{2} - 5N - 12 = 0

(3N + 4)(N - 3)

N = \frac{-4}{3}, 3

Because 3 is the only integer solution, the answer is 3 and 4.
