Step-by-step explanation:

Surface area = Base area + 3 x side triangles area

Compare Look at these equations. Do you think they are all linear equations? Can they
Georgia [21]

Answer:

Yes they can all be written in y = mx + b. You just have to move the terms around.

Step-by-step explanation:

y = 2x -3, this is already in slope-intercept form

Now, y - 2 = x + 2: We can add 2 on both sides to cancel out the one on the left side:

y - 2 = x + 2

y - 2 + 2 = x + + 2

y = x + 4 <-- This is in y = mx + b form

Now the last one, 3x = 9 + 3y

We can first divide all terms by 3,

3x = 9 + 3y

/3     /3   /3

x = 3 + y: Then we can subtract 3 from both sides:

x - 3 = 3 + y - 3

x - 3 = y

These are all linear equations because none of the x's have bigger powers than 1. x^2 is a quadratic equation and x^3 is cubic equation.

Approximately how much do i save per bottel of juice if i buy a pack of 8 rather than a pack of 6
Korolek [52]

Answer: Your question is missing information but this is what you do to answer your question step by step

B = Cost of 8 pack / 8 bottles  =  $ Cost of 8 pack/ 8 =$ ____ per bottle

A = Cost of 6 pack/ 6 bottles = $ Cost of 6 pack/ 6= $ ____ per bottle

then do a simple subtraction  A -B = savings

Step-by-step explanation:  Information is incomplete

if an 8 pack cost $16

If the 6 pack cost $15

All you do is a simple subtraction after calculations

Cost of 8 pack / 8 bottles  = $16/8 =$2 per bottle

Cost of 6 pack/ 6 bottles = $15/ 6= $2.50 per bottle

in my example  

You would save $ 0.50 per bottle by purchasing the 8 pack
