Answer:
Step-by-step explanation:
Proportional functions can be represented by , where is a constant of proportionality and represents any point the line passes through.
In the graph, we can see the line passes through (20, 40). Therefore, we can plug in these coordinates to find the constant of proportionality:

Step-by-step explanation:
If f(x) and g(x) are the inverses of each other, then
f(g(x)) = g(f(x)) = x
f(g(x)) = f(x - ) = x - + = x
g(f(x)) = g(x + ) = x + - = x
Hence f(x) and g(x) are the inverse of each other

Answer: -0.85
Step-by-step explanation:
3/10 + 1/5 = 1/2
1/2 x -4.25 = -0.85
Answer:
10,404/334,084
Step-by-step explanation:
Given the polynomial
289r^2 - 102r + c
We are to find the value of c that will make it a perfect square
Divide through by 289
289r²/289 - 102r/289 + c/289
Half of the coefficient of r is 1/2(102/289)
Half of the coefficient of r = 102/578
Square the result
r² = (102/578)²
r² = 10,404/334,084
Hence the required constant is 10,404/334,084
