the system of equations y=2x-1 and y=-1/4x+3 is shown on the graph below.

what is a reasonable estimate for the solution?

  (x, y) ≈ (1.8, 2.6)

Step-by-step explanation:

The point of intersection of the lines is perhaps 3/4 of the way between x=1 and x=2, and slightly over half the distance from y=2 to y=3. A reasonable estimate is ...

  (x, y) ≈ (1.8, 2.6)

The exact solution is (x, y) = (1 7/9), 2 5/9).

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°
