Answer:
Part 1) The value of x is 5
Part 2) The length of line AB is 5 inches
Part 3) The length of BC is 15 inches
Step-by-step explanation:
see the attached figure to better understand the problem
Part 1) Find the value of x
we know that
-----> equation A
we have
![AB=x\ in](https://tex.z-dn.net/?f=AB%3Dx%5C%20in)
![BC=3x\ in](https://tex.z-dn.net/?f=BC%3D3x%5C%20in)
![AC=20\ in](https://tex.z-dn.net/?f=AC%3D20%5C%20in)
substitute the values in the equation A and solve for x
![20=x+3x](https://tex.z-dn.net/?f=20%3Dx%2B3x)
![20=4x](https://tex.z-dn.net/?f=20%3D4x)
![x=5](https://tex.z-dn.net/?f=x%3D5)
Part 2) Find the length of line AB
we know that
![AB=x\ in](https://tex.z-dn.net/?f=AB%3Dx%5C%20in)
substitute the value of x
![AB=5\ in](https://tex.z-dn.net/?f=AB%3D5%5C%20in)
Part 3) Find the length of BC
we know that
![BC=3x\ in](https://tex.z-dn.net/?f=BC%3D3x%5C%20in)
substitute the value of x
![BC=3(5)=15\ in](https://tex.z-dn.net/?f=BC%3D3%285%29%3D15%5C%20in)
Hello:
an equation is : f(x) = a(x-4)² - 3
the point (5 , -6)in parabola : --6 = a(5-4)² --3
-6 =a -3
a =-3 is <span>the coefficient of the squared expression in the parabola equation</span>
