What are the solutions of the system?

{y=-6x-6
y=x^2-5x-6

answer choices:

a) (0, -1) and (0, -6)

b) (0, -1) and (-6, 0)

c) (-1, 0) and (-6, 0)

d) (-1, 0) and (0, -6)

D. (-1, 0) and (0, -6)

Step-by-step explanation:

The system of equations:

y = -6x - 6

y = x² - 5x - 6

We equate the two equations;

-6x - 6 = x² - 5x - 6

x² + x + 0 = 0

x² + x = 0

x(x + 1) = 0

So, x = 0 or -1

When x = 0,

Then y = -6(0) - 6 = -6

When x = -1,

Then y = -6(-1) - 6 = 6 - 6 = 0

So the answer is: (0, -6) and (-1, 0)

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
