6- 2/5 * x = 3y + 8x is nonlinear or linear

is a linear equation

Step-by-step explanation:

Given:

For a equation to be linear it must be in the form of

Where a, b and c are constants.

The given equation on simplifying we get

∴

Which is in the form of

where

Which is linear.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
