Answer:

Total no of ways can a combo containing 2 burgers, 3 different sides, 2 different flavor drinks, and 3 ice cream flavors be made = 529,200

Step-by-step explanation:

Given -

A fast-food restaurant offers 6 different burgers, 6 different side orders, 7 different flavor drinks, and 9 different flavors of ice cream .

choose 2 burgers from 6 different burger = $\binom{6}{2}$

choose 3 different sides from 6 different side orders = $\binom{6}{3}$

choose 2 flavor drinks from 7 different flavor drinks = $\binom{7}{2}$

choose 3 ice cream from 9 different flavors of ice cream = $\binom{9}{3}$

Total no of ways can a combo containing 2 burgers, 3 different sides, 2 different flavor drinks, and 3 ice cream flavors be made=

= $\binom{6}{2}\times\binom{6}{3}\times\binom{7}{2}\times\binom{9}{3}$ ( Using combination )

= $\frac{6!}{(2!)(4!)}\times\frac{6!}{(3!)(3!)}\times\frac{7!}{(2!)(5!)}\times\frac{9!}{(3!)(6!)}$

= $15\times20\times21\times84$

= 529,200

I got 3; M=-4 so you plug that in and get -4^2+5(-4)+7
-4 times -4=16
5 times -4=-20
16+(-20)=-4
-4+7=3

What is the solution to the open sentence? 4y – 3 = y + 6 A. 1 B. 2 C. 3 D. 9

azamat

4y - 3 = y + 6
Add 3 to both sides
4y = y + 9
Subtract y from both sides
3y = 9
Divide both sides by 3
y= 3
