Step-by-step explanation:
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the solid line
-----> inequality B
The solution of the inequality B is the shaded area above the solid line
Using a graphing tool
The solution of the system of inequalities is the shaded area indicated in the attached figure
<span>Here's the official formula:
If you have two points :
L(a,b) and M(c,d)
slope=(d-b)/(c-a)
We have:
M(20,22) and L(12,6)
slope=(22-6)/(20-12)=16/8=2</span>
B. The square root function is the quadratic function reflected across
the line y = x, with a limited domain.
graph y=x^2 and y=√x and y=x
graph is attached

Factor them
19x^7=19*x*x*x*x*x*x*x
3x^5=3*x*x*x*x*x
common group is x*x*x*x*x or x^5
gcf is x^5
