Which equation do you mean?
the value of the dimes is 10(21 - 5)
hope this helps
Replace x in the equation for f(x) with -5:
|2x +9| = |2(-5) +9| = |-10 +9| = |-1| = 1
Now find x 1 and see where the graph of G(x) crosses the Y :
It crosses ay Y = 5
The answer is A. 5
C = 8.5x + 6y
Rearrange the equation by making the side with x, be on the Left Hand Side (LHS)
8.5x + 6y = C
Subtract 6y from both sides of the equation
8.5x + 6y - 6y = C - 6y
8.5x = C - 6y
Divide both sides of the equation by 8.5
(8.5x/8.5) = (C - 6y)/8.5
x = (C - 6y)/8.5
I hope this helped.
Answer:
![x=0,x=-4,x=-3](https://tex.z-dn.net/?f=x%3D0%2Cx%3D-4%2Cx%3D-3)
Step-by-step explanation:
The given equation is
![x^3 + 7x^2 + 12x = 0](https://tex.z-dn.net/?f=x%5E3%20%2B%207x%5E2%20%2B%2012x%20%3D%200)
Factoring by x:
![(x^2 + 7x + 12)x = 0](https://tex.z-dn.net/?f=%28x%5E2%20%2B%207x%20%2B%2012%29x%20%3D%200)
One of the root is x=0. Let's solve the parentheses.
Expanding the trinomial
![x^2 + 4x+3x + 12=0](https://tex.z-dn.net/?f=x%5E2%20%2B%204x%2B3x%20%2B%2012%3D0)
Factoring
![x(x + 4)+3(x + 4)=0](https://tex.z-dn.net/?f=x%28x%20%2B%204%29%2B3%28x%20%2B%204%29%3D0)
Factoring
![(x + 4)(x+3)=0](https://tex.z-dn.net/?f=%28x%20%2B%204%29%28x%2B3%29%3D0)
This will give us the two remaining roots
![x=-4,x=-3](https://tex.z-dn.net/?f=x%3D-4%2Cx%3D-3)
