x = - [tex]\frac{14}{3}[/tex]
Step-by-step explanation:
Given
[tex]\frac{3}{4}[/tex] (x + 5 [tex]\frac{1}{2}[/tex] ) = [tex]\frac{5}{8}[/tex]
Multiply both sides by 8 to clear the fractions
6(x + 5 [tex]\frac{1}{2}[/tex] ) = 5 ← distribute parenthesis on left side
6x + 33 = 5 ( subtract 33 from both sides )
6x = - 28 ( divide both sides by 6 )

What is the Inverse function?An inverse function is a function which reverses the function direction for which the range of the function becomes the domain and the domain of the function becomes the range of the inverse function.
If y = f(x) is the given function then x = f⁻¹(y) is the inverse function.
Here, given in the question the value of x and the value of f(x).
for which f(-1)= -3
f(1)= -1
f(4)= 1
f(6)= 4
f(7)= 6
So let the value of f(x) is y
we can write y=f(x)
applying inverse on both side
⇒f⁻¹(y)= f⁻¹(f(x))
⇒f⁻¹(y)= x
⇒ x= f⁻¹(y)
given that the inverse of f(x) is g(x)
so now the equation will be
⇒ x= f⁻¹(y)=g)y)
⇒ x= g(y)
according to the above function at the value of y, the inverse of the function will be g(y)= f⁻¹(y)
so from the table it is clear that at the value of x=4, f(x)=y=1.
So at y=1, 1=f(4)
so applying inverse on both side
⇒ f⁻¹(1)= f⁻¹(f(4))
⇒ f⁻¹(1)= 4
⇒g(1)= 4
Therefore the value of the g(1)= 4.

As the weather changes from Summer to Fall, it was noted that the temperature dropped 20°F over 4 weeks. It continued to drop the same amount of degrees for each week. Write an integer that represents the change in temperature each week. Explain.
Answers
Answer:
The integer that represents the change in the temperature each week = 5
The temperature of the weather drops 5°F each week
Step-by-step explanation:
The given parameters regarding the weather are;
The range over which the temperature dropped = 20°F
The duration over which the temperature dropped = 4 weeks
The rate at which the weather dropped each week = The same amount (constant rate)
Therefore, we have;
For a constant rate of change, the rate of change of the temperature of the weather, m, is given as follows;
m = (The change in the temperature)/(The duration of the change)
m = 20°F/(4 weeks) = 5°F/week
The integer that represents the change in the temperature each week = 5
