Using the substitution method, we can plug equation 1 into equation 2 (in place of x) as a result we see:
<span>x + 4 = 3x + 6</span><span /><span>

Answer:
y=1.09x+0.4
Step-by-step explanation:
Let's assume that the price of beef stays the same for every pound of beef (the first pound is also $1.09)
Then, the equation would be, it y was the cost, and x was pounds:
y=1.09x
But, the price of beef is not the same for the first pound.
The first pound costs an extra 1.49-1.09=0.4 dollars a pound, so we will add that to the equation.
y=1.09x+0.4
It’s less than a positive number
