Answer:
x= 143/184
Step-by-step explanation:
23 times 8x= 184x
23 times -6= -138
5= 184x-138
add 138 to both sides
143= 184x
x= 143/184
Y=x^3+5
y^-1=....
example >>a=x^3+5
a-5=x^3
3√a-5=x
y^-1=3√x-5
Just multiply the cost by the tax rate (use the decimal fraction 0.0625 for this):
0.0625($498) = answer
You haven't provided a graph for us to see but the graph should look like a diagonal line going from the bottom left to the top right and the point of intersection on the y axis is -2

Answer:
1/(3x) =(x -2)/(4x^2 +9)
Step-by-step explanation:
The denominator cannot be factored further, so the final form will be ...
A/(3x) + (Bx +C)/(4x^2 +9)
The value of this is ...
(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))
= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))
Equating coefficients gives ...
3B+4A = 7
3C = -6 ⇒ C = -2
9A = 9 ⇒ A = 1
Using the found value of A, we find ...
3B +4 = 7 ⇒ B = 1
Then the decomposition is ...
