The solution to the system of inequalities is (-3.375, 1.75)
<h3>How to graph the inequalities?</h3>
The system of inequalities is given as:
3y > 2x+12
2x+y < -5
Next, we plot the graph of the system using a graphing tool
From the graph, both inequalities intersect at
(-3.375, 1.75)
Hence, the solution to the system of inequalities is (-3.375, 1.75)

The external angle between the secants (20°) is half the difference of the intercepted arcs.
(75° - B)/2 = 20°
75° - B = 40°
75° - 40° = B = 35°
Answer: 
Step-by-step explanation:
Given
The plane is cruising at an altitude of 
The angle of depression is 
Suppose the distance of the plane to the runway is x
from figure
First, set up what you know. Twice the sum of a number and seven means: 2x+7. Three times the difference of the number and 8 is 3(x-8).
Set both of them equal to each other and you'll get this:
2x+7 = 3(x-8)
Afterwards just follow through with algebra.
2x+7 = 3x - 24
2x + 31 = 3x
31 = 3x - 2x
31 = x
Afterwards check your work to see if it is correct.
2(31) + 7 = 3( 31 - 8 )
62 + 7 = 3(23)
69 = 69
An angle that turns through 1/360 of a circle is called a "one-degree angle," and can be used to measure angles.
