Answer:
x= 3
Step-by-step explanation:
Given data
Ratio= 5:2:x
Combined ratio= 5+2+x
= 7+x
Total amount of money= $15000
Let us apply the part to all method
Hence for Matthew whose share = $7500
5/7+x= 7500/15000
Cross multiply we have
7500*(7+x)= 15000*5
52500+7500x= 75000
Collect like terms we have
7500x= 75000-52500
7500x=22500
x= 22500/7500
x=3
Hence the value of x= 3

Answer:
B
Step-by-step explanation:
The graphs of the function and of its inverse function are always symmetrical about the line y = x.
The diagram shows the graph of the function f(x) (blue line).
The line with the equation y = x is the I quadrant bisector, so symmetrical graph to the grph of f(x) is red graph - graph of the function g(x).
Hence, correct option is B.
