the equation here would be set up by doing
44.4 - 10.9 = 33.5
Carlsbad caverns is 33.5 kilometers long.
The answer is -3 because you’re plugging g(x) into f(x). For every x there is in f(x), plug in g(x)’s equation. After you get another equation (simplified), which is x^2 -7x -11, plug -1 for every x and condense.
We know that, Volume of a Rectangular Prism is given by :
✿ {Length × Width × Height}
Given : The Length of Rectangular Prism = 5.5
Given : The Width of Rectangular Prism = 6
Given : The Height of Rectangular Prism = 3
⇒ The Volume of given Rectangular Prism = {5.5 × 6 × 3}
⇒ The Volume of given Rectangular Prism = 99
A. Let x = cheese and
y = chocolate
2x + y = 25
x + y = 20
B. Subtract the second equation from the first.
2x + y = 25
-(x + y = 20)
-—————
x = 5
Plug 5 back in to the second equation and solve for y.
x + y = 20
5 + y = 20
Subtract 5 from both sides.
y = 15
5 cheese and 15 chocolate
Used elimination method because coefficients on the y values were both 1 so it was easy to subtract the equations and eliminate the y variable.
