Emily wants to buy turquoise stones on her trip to New Mexico to give to at least 4 of her friends. The gift shop sells small stones for $4 and large stones for $6. Emily has $30 to spend. a. write and graph a system of linear inequalities
b. write two possible solutions

Step-by-step explanation:

s for small stones

l for large

4s+6l<=30 (<= means less or equal to because I couldn't get the sign on here).

s+l>=4. (>= means greater than or equal to).

Possible Answers:

s+l=5 (if she bought 5 stones in total)

answer #1: 5 large stones and 0 small stones.

s+l=6 (if she bought 6 stones in total)

answer #2: 3 large stones and 3 small stones.

so sorry i couldn't do the graphing part...

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
