Identify in the given expressions, terms which are not constants. Give their numerical coefficients. (i) 5x – 3
(ii) 11 – 2y2
(iii) 2x – 1​

Given:

The expression are

(i)

(ii)

(iii)

To find:

The terms which are not constants and their numerical coefficients.

Solution:

Constants: The terms which are free from variables.

Numerical coefficient: Number multiplied with a variable.

(i)

Constant = -3

Term which is not constant = 5x

Numerical coefficient = 5

(ii)

Constant = 11

Term which is not constant =

Numerical coefficient = -2

(iii)

Constant = -1

Term which is not constant = 2x

Numerical coefficient = 2

Therefore, the terms which are not constants are    respectively and their numerical coefficients are 5, -2, 2 respectively.

so, converting firstly the mixed fractions to improper fractions and then "adding".

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
