Which is a factor of 5xy − 40x − 15y + 120? A. 2 B. y − 8 C. x − 4 D. x + 6

1 answer:

5 0

Upon slight rearranging:

5xy-15y-40x+120, now factor 1st and 2nd pair of terms

5y(x-3)-40(x-3) which is equal to:

(5y-40)(x-3) if we factor the first parenthetical term as well

5(y-8)(x-3)

So (y-8) is a factor

Answer: 30 $15 tickets and 20 $35 tickets

Step-by-step explanation:

.X%2BY=50

2.15X%2B35Y=1150

From eq. 1,

15X%2B15Y=750

Subtract from eq. 2,

15X%2B35Y-15X-15Y=1150-750

20Y=400

Y=20

Then,

X%2B20=50

X=30

30 $15 tickets and 20 $35 ticket
