The number of grasshoppers is twice the number of crickets. Find the number of
each type of insect that she has
Answer:
k = 2/3 x
y = 2/3.
Step-by-step explanation:
y = kx where k is a constant
y = 2 when x = 3 so:
2 =k*3
k = 2/3.
The equation is y = 2/3 x.
When x = 1
y = 2/3 * 1 = 2/3.

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
