I=0.13x+1025 A textbook salesperson's monthly income depends on the amount of his sales. His monthly income is a salary of $1025 $ ⁢ 1025 plus 13% 13 % of his monthly sales. Write a linear equation for his monthly income for sales of x dollars. ( I=mx+b I = m x + b ).

l = 0.13x+1025

Step-by-step explanation:

Let the monthly sales be x

Monthly income = $1025 + 13% of monthly sales

Monthly income = $1025 + 0.13x

Since l  represent the monthly income

l = 1025+0.13x

Rearrange

l = 0.13x + 1025

Hence the linear equation representing the statement is l = 0.13x+1025

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
