Rewrite as:
4y=x^2-12x+68
divide by four:
y= x^2/4-3x+17
your answer would be
(6,8)
This is not possible, because if you had 11 coins, then not even 11 dimes will cover it, because 11*10 is 110, or $1.10
15-3b=63
subtract 15 from both sides
-3b=48
divide -3 from both sides
b= -16
Answer:
28 eggs
Step-by-step explanation:
It takes a hen and a half to lay an egg and a half in a day and a half - this means it takes 1 hen to lay 1 egg in a day and a half. Therefore, 1 hen will lay 4 eggs in 6 days, and 7 hens will lay 28 eggs in 6 days.
Answer:
C.
Step-by-step explanation:
y = 6x
if x = 1 , y = 6
if x = 2 , y = 12
if x = 3 , y = 18
if x = 4 , y = 24
