Answer:
y = 52
x = 30
Step-by-step explanation:
Hi!
Y is a vertical angle. See <DOB? That's it's vertical pair. So, y = 2x - 8 [vertical angles are congruent].
Now, to find y, we need x. We can find x by using the fact that AB is a straight line. The angles on a straight line add up to 90.
Given the fact that <AOB is 90 degrees, <EOB also has to be 90 degrees.
So, EOB = 90 degrees. Remember that an angle is equal to the sum of the measures of the angles that it is made of.
EOB is therefore equal to <EOD + <DOB.
90 = <EOD + DOB
90 = (x +8) + (2x-8)
90 = 3x
x = 30
Check:
38 + 52 = 90.
So, x = 30
Now, we go back to find y.
y = 2x-8
y = 52
1. Combine all of the like terms so that you can simplify it, if they are not combined already.
2. Drop all of the constants and coefficients, the constant terms are all of the terms that are not attached to the variable.
3. Put the term in decreasing order of their exponents.
4. Find the power o the largest term.
5. Identify the degree of the polynomial.
6. Know that the degree of a constant is zero.
Hope this helps!
Answer:
0≥6y
Step-by-step explanation:
y-5(y+1)≥2y-5
y-5y-5≥2y-5
-4y≥2y
0≥6y
OK. Then let's solve for ' r '. That means you have to come up with an equation that says r = everything else.
Step #1:
Write the equation you're given: <span>S = L (1 - r)
Let's divide each side by ' L ': S/L = 1 - r
Subtract 1 from each side : S/L - 1 = -r
Multiply each side by -1 : <em> 1 - S/L = r</em>
and there you have it.

The correct equilibrium constant expression for this equation is;
Given
Consider the equation below.
<h3>What are Species?</h3>
In an equilibrium constant expression, you do not include the solid substances; only gases and dissolved substances.
<h3>Equilibrium constant expression;</h3>
It is the quotient of the product of the concentrations of the species on the right-hand side of the equilibrium equation, each raised to its corresponding coefficient, and the product of the concentrations of the species on the left-hand side, each raised to its corresponding coefficient.
Therefore,
The correct equilibrium constant expression for this equation is;
Hence, the correct equilibrium constant expression for this equation is;
.
