Answer:
You can use graphing to determing whether (5, 2) is a solution to the system of inequalities by creating a line going from the origin (0,0) and bring the line to (5, 2). Using this, you can find the x & y intercept, slope, etc.
Step-by-step explanation:
Answer:
1) The value of c is given by

2) The value of k is given by

Step-by-step explanation:
Given that function g is defined by
, where c is a constant.
To find c:
Also given that value of g(x) at x=0.5 is equal to -1
ie., 
At x=0.5






Therefore 
2) Given that function h is defined by
, where k is a constant.
To find k:
Also given that value of h(x) at x=20 is equal to 65
ie., 
At x=20



Therefore 
Answer:
x^2 ÷4
Step-by-step explanation:
f(x) = ( 4x) ^1/2
y = (4x)^1/2
x = y^2 ÷ 4
then, inverse fun. is x^2 ÷ 4
B

5,000
because the library has more than or = to 5000 books.
