Answer:
w > -15
Step-by-step explanation:
(w/5-5>-8)5
w-25>-40
w>-40+25
w > -15
Step-by-step explanation:
slope(m)= y2-y1/x2-x1
-2-6/4+2
= -8/6
= -4/3
Answer:
2 cookies
Step-by-step explanation:
let c represent cookies, m represent muffins. set up a system of equations:
2c+3m=16
m=2c
(the top equation shows that cookies are $2 each, and muffins are $3, and that the total cost is $16. the bottom equation shows that Lori bought twice as many muffins as cookies).
then solve the system of equations by substitution, substituting 2c for m in the top equation:
2c+3(2c)=16
2c+6c=16
8c=16
c=2
this means that lori bought 2 cookies.
