If y varies directly as x, and x = 3 and y = 9, solve for k Write an equation that relates x & y
If y varies inversely as x, and x = 3 and y = 12, Solve for k Write an equation that relates x & y

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

step-by-step explanation:

2.24/7

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°
