Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
To Determine: find the two negative numbers.
Given: a negative number is 2/5 of another negative number.if the sum of the two negative number is -35.
Explanation: let us consider (-x) and (-y) be the two number .
from the given condition we have
a negative number is 2/5 of another negative number.
from the second condition
if the sum of the two negative number is -35, so we have
so solve the equation by multiplying equation 2 by 2 and adding both the equations then we have .
