Large reusable bottles cost $4 more than small ones. Eight large bottles cost $24 less than 12 small ones. How much does one sma
ss7ja [257]
A small bottle costs $14.

To solve the problem, the equation would be this:

 8(4+s)=12s-24

Let <em>s </em>represent a small bottle. Since one large bottle is $4 more than a small one, you would write out <em>(4+s)</em>. Then, multiply it by 8 to find one side of the equation, and get <em>8(4+s)</em>. To write out the right side of the equation, you would write out <em>12s </em>to represent 12 small bottles, and <em />subtract <em />24 from that to represent that 8 large bottles is $24 less than 12 small ones. 

Then, proceed to solve the equation to get the answer of <em>s=14</em>. Because a small bottle is $14, you can check your work by substituting the 14 in replace of <em>s</em>. <em />

What is the y-intercept and slope <br> of the line
bezimeni [28]

Answer:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".

Brilliant_brown [7]

Answer:

y = 2x + 54

Step-by-step explanation:

slope of equation:

(y2-y1)/(x2-x1)

= (72-58)/(9-2)

= 14/7

= 2

y = 2x + b

58 = 2(2) + b

58 = 4 + b

b = 54
