Answer:
30 seats
Step-by-step explanation:
To answer this question, we will be assigning values for both rows and seats.
R = Rows
S = Seats
Remember that rs = 600
r = s - 10, plug this equation into rs = 600, and factor it:
s(s-10) = 600
s^2-10s-600 = 0
(x-30)(x+20) = 0
There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.

Option D is the correct answer
Answer:
To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.

Step-by-step explanation:
When a graph is reflected about the x-axis, their x-intercept(s) are invariant point(s).
For y = 2x + 3, the x-intercept is -3/2.
Also the slope of the line graph when reflected about the x-axis will change from m to -m.
Therefore the new slope is -2.
We have y = -2x + c.
When x = -3/2, y = 0.
=> (0) = -2(-3/2) + c, c = -3.
Hence the answer is y = -2x - 3. (E)
