x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
x=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

Step-by-step explanation:
(-8+2)/(8-8)= -6/0= undefined
Step-by-step explanation:
When w=10, 7w=7×10=70
But the given value of 7w is 73.
So, the given value is not a solution of the equation.
The rate of descent is <em>164.64 meters / minute
</em><em />
<em />To get this answer you just divide the total number of meters descended by the total number of minutes passed.
<em>
</em>So:<em>
</em>922.02 ÷ 5.5 = 164.64
I hope this helped!! Have an amazing day! :D
Answer:
There will be approx 283908 hits.
Step-by-step explanation:
A website had 342,000 hits in 2011.
This is a decline of 2.3% from the previous year.
Decline rate = 2.3% or 0.023
So, increase rate will be 
Time = 
We can calculate the answer as:

= 
= 283907.88 rounding to 283908.
Therefore, there will be approx 283908 hits.
