Answer:
x = - 5/2 or x = - 3/2
Step-by-step explanation:
|-2(x+2|=1
|-2x-4|=1
- 2x - 4 = 1 or - 2x - 4 = - 1
- 2x - 4 = 1
- 2x = 4+1
x = - 5/2
or -2x - 4 = - 1
-2x = 4 - 1
x = - 3/2
Answer:
Y=77/x
Explanation:
Y varies inversely with x meaning

adding a proportionality constant gives

Now, we are told that y = 11 and x = 7; therefore, the above gives

Solving for k gives

Therefore, the function that models the inverse variation is

which is our answer!
Tan = opp/adj
Tan A = 16/12
