Answer:
(-1, -2)
Step-by-step explanation:
when x = -1 and y = -2,
(-2 · -1) - (-2) = 2 + 2 = 4
i dont know the answer, but i reccommend using mathpapa.com as they give you the answer PLUS the explaination.
To get the answer, you need to solve the equation for x = 7.
f(7) = 3/7 + 2 - sqrt(7) - 3.
= 3/7 - 1 - sqrt(7).
If you need to simplify it further:
= -4/7 - sqrt(7).
If you need it in decimal form: = -3.2171798824
The number of soda bottles Katie bought is 6
The given parameters are:
- Large Pizza = $14.99
- Soda = $1.50 per bottle
- Total cost = $23.99
Assume the number of soda bottle is x.
So, we have:

This gives

Subtract 14.99 from both sides of the equations

Divide both sides of the equations by 1.5

Rewrite the equation as

Hence, the number of bottles is 6
