Answer:
y = 4/5x - 9/5
Step-by-step explanation:
4x - 5y = 9 to solve for y you get it by itself.
-4x -4x minus 4x from both sides
-5y = - 4x + 9
/-5 /-5 Divide both sides by 5
y = 4/5x - 9/5 because -4/-5 is 4/5 and 9/-5 is - 9/5

Answer:
Heidi (260 cookies)
Step-by-step explanation:
Megan's equation is given as y=8x, where x is the number of bags, and y the number of cookies:
#First calculate Heidi's total number of bags, cookies and cookies:

#Given that both Heidi and Megan make the same number of bags of cookies, Megan's cookies totals to:

Hence, Megan makes 416 cookies.
#From our calculations:

Hence, Heidi makes the least number of cookies(260 cookies) compared to Megan's 416 cookies.
