Answer:
<h2>16.26</h2>
Step-by-step explanation:
Pythagorean Theorem | a^2 + b^2 = c^2
1) Plug in a & b
<h2>11^2 + 12^2 = c^2</h2>
2) Rewrite
<h2>c =

</h2>
3) Solve
<h2>c = 16.2788206</h2>
4) Round
<h2>16.26</h2>
Answer:
Part A) The graph in the attached figure
Part B) see the explanation
Step-by-step explanation:
Part A) Graph the function
we have the quadratic function

This is a vertical parabola open upward
The vertex is a minimum
using a graphing tool
The graph in the attached figure
Part B) What are the values of a, b and c?
we know that
The values of a and b represent the x-intercepts of the quadratic equation
The x-intercepts are
(-2,0) and (6,0)
so

Find the value of c
we know that
The x-coordinate of the vertex in a vertical parabola is equal to the midpoint of the roots
so
The value of c is equal to

substitute the given values

see the attached figure
Answer:
D
-5x + y = 7
x+3y = 5
Step-by-step explanation:
when you graph the equations, they are parallel. as you know, solutions are the point where the lines meet. if they are parallel, it's not possible for the lines to intersect.
