The first 3 rows are proportional
because when you divide the earning by car washed they all have the same unit rate of 9.5/ to answer the second part you multiply 9.5 by 88. you'll get $836
The height is going to be 10.6
7(2e - 1) - 3 = 6 + 6e
14e - 7 - 3 = 6 + 6e
14e - 10 = 6 + 6e
- 6e
8e - 10 = 6
+ 10
8e = 16
÷ 8
e = 2
Hope this helps!
Answer: Completing the square changes the value of the equation.
Step-by-step explanation:
For example we have expression : ![x^2+ax](https://tex.z-dn.net/?f=x%5E2%2Bax)
which is equivalent to ![x^2+2\frac{a}{2}x](https://tex.z-dn.net/?f=x%5E2%2B2%5Cfrac%7Ba%7D%7B2%7Dx)
We add and subtract
to form a complete square.
![x^2+ax+(\frac{a}{2})^2-(\frac{a}{2})^2](https://tex.z-dn.net/?f=x%5E2%2Bax%2B%28%5Cfrac%7Ba%7D%7B2%7D%29%5E2-%28%5Cfrac%7Ba%7D%7B2%7D%29%5E2)
, where
is a perfect square binomial.
Thus, the true statements about the completing squares are:-
- Completing the square will always work.
- When completing the square you add and subtract the same value to the equation.
- When completing the square you create a perfect square binomial.
Completing the square does not change the value of the equation.
Ok so we know that each combo meal is $5. So 24 x 5 = $120
$6 service charge has to be divided by 120.
6/120 = 0.05
