$4.00 because
$15 - $7 = $8 than divide it by 2 which gives the $4 dollars for each 2 people
Amy can estimate with 10% instead, so she can just simply move the decimal point of $9.11 to the right, and so it will be estimated to more than 91 cents.
Answer:
Yes, the graph represents a proportional relationship. No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0).
The answer is:
x=-8
Because:
If you pick a number(-8) to fill in the equation written below
5x+20+5x=5x-20
After applying the -8 to x you get
-40+20-40=-40-20
When you simply the both sides you get
-60=-60
And that’s right -60 is equal to -60!
Answer:
The quadratic equation is: 
Step-by-step explanation:
If the roots of the quadratic equation are "-6" and "6", then it must have the following factors: 
Therefore, we can write the equation in factor form as:
where a is a real number constant factor. Now, this equation in standard form will look like:
Therefore, using the information about the leading coefficient being "1" (one), we derive that the constant factor 
must be "1". The final expression for the quadratic becomes:
