So we know that the slope intercept form is y=mx+b
so the formula is y=3*-3+-6
I think the ratio is for for every 4 packs it cost 10 dollars so in all it would cost 30 dollars
To get you answer multiply .3 and 2.7
Answer:
12x − 2
Step-by-step explanation:
7(x+4)+5(x−6)
Distribute:
=(7)(x) + (7)(4) + (5)(x) + (5)(−6)
=7x + 28 + 5x − 30
Combine Like Terms:
=7x + 28 + 5x − 30
=(7x+5x) + (28−30)
= 12x − 2
