Let the unknown number be x.
5/11 * x = 55
Since x is being multiplied by 5/11, and you want x alone, you need to multiply both sides of the equation by the reciprocal of 5/11 which 11/5.
11/5 * 5/11 * x = 55/1 * 11/5
x = 605/5
x = 121
Answer: The number is 121.
Equation is y = -1/6x
Step-by-step explanation:
- Step 1: Given that slope, m = -1/6 and a coordinate (12,-2). Write the equation and find the y-intercept, b.
⇒ y = mx + b
⇒ -2 = -1/6 × 12 + b
⇒ -2 = -2 + b
∴ b = 0
- Step 2: Write the equation in slope intercept form.
⇒ y = -1/6x + 0
⇒ y = -1/6x
Answer: B 
Step-by-step explanation:
From the given table
When x changes from 1 to 2 , value of y changes from 6 to 4
The multiplicative rate of change=
Similarly we can check
When x changes from 2 to 3 , value of y changes from 4 to 
The multiplicative rate of change=
When x changes from 3 to 4 , value of y changes from
to 
The multiplicative rate of change=
Therefore, the multiplicative rate of exponential function = 
(8-3)²-(5-2)²
Follow the PEMDAS
P-Parenthesis
E-Exponents
M/D-Multiplication/Division
A/S-Addition/Subtraction
clear the numerals in the parenthesis:
(5)²-(3)²
Now do the exponents:
=25-9
=16
Its just: (5)²-(3)²
