-2x +5 < 7
-2x < 2 . . . . . . subtract 5
x > -1 . . . . . . .. divide by -2, which reverses the relationship
The 1st selection is the correct one.
___
Check
Choose x = 0 > -1.
.. -2*0 +5 < 7
.. 5 < 7 . . . . . . . . . . true
Choose x = -1, not in the solution set.
.. -2*-1 +5 < 7
.. 7 < 7 . . . . . . . . . . not true, as expected
-9 + 2 = 7
7 + 9 = 16
X = 16
Answer:
14.48 ft
Step-by-step explanation:
The relation between the location of the focus (c), the vertex on the major axis (a) and the vertex on the minor axis (b) with respect the center is:
b² = a² - c²
From the question:
c = 4 ft
a= 30/2 = 15 ft
Replacing into the equation:
b² = 15² - 4²
b = √209
b = 14.48 ft
So, he should build the whisper chamber at 14.48 ft out from the center along the minor axis
