Alexandra has $15 to buy drinks for her friends at the baseball game. soda costs $2.75 and bottled water costs $2.00. this relationship can be represented by the inequality 2.75s+2w

Step-by-step explanation:

Let

s-------> the number of sodas

w-----> the number of bottled water

we know that

The inequality that represent the situation is equal to

using a graphing tool

The solution is triangular shaded area

see the attached figure

The domain (number of sodas) is all positive whole numbers belong to the interval [0,1,2,3,4,5]

The range (number of bottled water) is all positive whole numbers belong to the interval [0,1,2,3,4,5,6,7]

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
