Answer:
The point ( 0,-1) is a solution.
Step-by-step explanation:
y<= (x+1) (x+5)
y>= (x-1)^2 -6
See attached graph.
To prove algebraically, put the point (0,-1) into both equations and see if it is true for both of them.
y<= (x+1) (x+5)
-1 <= (0+1) (0+5)
-1<= 1*5
-1 <=5
True
y>= (x-1)^2 -6
-1 >= (-1)^2 -6
-1 >= 1-6
-1 >=-5
True
The point is a solution
Answer:
Step-by-step explanation:
A triangles angles add up to 180°. We know two angle measures in the triangles and, since they are similar, they will have the same measure. You can mirror the measures from one triangle to another. Solve for the unknown angle:
a represents the unknown angle adjacent to 3x btw
the missing angle measure is 38. Now, we can see that there is a straight angle (180°) that unites 16°, 3x°, and the angle that is now known as 38°. So we add the known degrees together
Subtract from the total value of 180
126 is the obtuse angle measure, so now solve for x
