(Pretest Unit 3) Which graph correctly represents 5/2x - y < 3 ? (Zoom in)

Graph C represents   x - y < 3 correctly

Step-by-step explanation:

Let us revise some important notes about the solutions of an inequality

∵ The inequality is x - y < 3

- Put the inequality in the form y less than or greater than m x + b

∵   x - y < 3

- Add y to both sides

∴ x < 3 + y

- Subtract 3 from both sides

∴   x - 3 < y

- That means y is greater than   x - 3

∴ y >   x - 3

∵ The sign of the inequality is >

∴ The line is dashed

∴ The shading is above the line

- Look to the answer to find the correct answer

∵ In figure C, the line is dashed

∵ The shading is above the line

- C only has the two conditions

∴ Graph C represents   x - y < 3 correctly

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°
