it costs $6.95 to ship a 4-pound package and $9.35 to ship a 7-pound package. the shipping charge can be modeled by a linear function of the form y= mx + b, where y represents the shipping charge in dollars and x represents the weight of the package in pounds. what is the cost to ship a package that weighs 13 pounds?

answer: h

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
