Write the following using algebraic notation, using the letter x for any unknown numbers: I think of a number, subtract three then multiply by four

a) The  algebraic notation is     4 ( x -3 ) = 4x -3

b)  The algebraic notation is 2x +2

Step-by-step explanation:

Explanation:-

a)

Let 'x' be the number

Given 'x' is a number, subtract three

⇒ x - 3   and multiply '4'

The result of algebraic is     4 ( x -3 ) = 4x -3

b)

Let 'x' be a number and add one

⇒ (x+1) and then double

∴ The algebraic notation is

    (x+1 ) (2) = 2x +2

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

they disappear if your absent from to long. i found out that the hard way.
