Answer:
Step-by-step explanation:
The expression (t•s)(x) means t(s(x)) or t of s of x. It means to substitute s(x) into the equation for t(x).
Answer: Point A represents Q1, Point B represents the Median, Point C represents Q3

Answer:
a) y = 16/x²
b) x = 4/5
Step-by-step explanation:
You want the equation for y in terms of x when y is inversely proportional to the square of x, and y is 16 when x is 1. Further, you want the value of x when y is 25.
<h3>(a) Relation</h3>
The wording "inversely proportional to the square" means the form of the equation is ...
y = k/x² . . . . . . where k is the constant of proportionality
The value of k can be found from the given (x, y) pair.
k = x²y = (1)²(16) = 16
The equation is ...
y = 16/x²
<h3>(b) Value of x</h3>
Solving for x gives ...
x = √(16/y)
Then the value of x for y = 25 is ...
x = √(16/25)
x = 4/5
Answer: 4
Step-by-step explanation:
Let assume the number to be = x
The second statements stated that
6 ˣ x + 3 = 3 ˣ 9
6x + 3 = 27 , solving the simple linear equation,
6x = 27 - 3
6x = 24, and by dividing through by 6
x = 4
Therefore , the number is 4
