Answer:
tanθ = 
Step-by-step explanation:
By applying tangent rule in the given right triangle ROE,
tanθ = 
tanθ = 
tanθ =
Therefore, answer will be tanθ =
Answer:
1/9 or .11111111111111111111111111111111111111...
Step-by-step explanation:
The power of two means that it will be 9, but the negative power means it will be the denominator and 1 will be the numerator (top number).

Hope it helps and is correct!
Answer:
x = 25.35 (or 2129/84) and y = 4334.04 (or 121353/28)
Step-by-step explanation:
The given equations are set up and ready to go with substitution. Simply just plug in the first equation to the second equation as both are equal to y.
Step 1: Replace y in <em>y = 87x + 2129 </em>with <em>171x</em>
171x = 87x + 2129
Step 2: Subtract 87 x on both sides
84x = 2129
Step 3: Divide both sides by 84 to get x
x = 2129/84 or 25.35 (rounded)
To get y, simply plug in x into one of the 2 original equations. In this case, I will use the first equation:
y = 171 (25.35)
y = 121353/28 or 4334.04 (rounded)
You can check your work by plugging both solutions into the calculator and see if they equal each other. The values for these answers are solely based on the equations, so if you write the <em>equations </em>wrong themselves, then that means you have the values wrong as well.
Answer:
If a quadratic function is not discriminating at 0, it does not have any real roots and it does not intersect the x-axis in the parabola it serves.
Step-by-step explanation:
The equation has no true solution if the discriminant is less than 0.
