Y=3x=4 , 9x-3y=-6 do the lines intersect or are they parallel or perpendicular

Lines are parallel.

Step-by-step explanation:

The given lines are

Rearrange the equation in the slope intercept form that is where is the slope.

First Line:

compare it with

slope () of first line

Second Line:

divide both by

compare it with

slope of second line

Since slope of two lines are equal

hence these lines are parallel.

the answer is $4.45. i started by figuring out the cost of the plates and napkins. the easiest way to figure this cost out is through the tax. we know the way they found the tax is by multiplying the cost of non-food items by the tax rate (5% or 0.5). so, all we have to do to find the cost before tax is set up an equation and work this formula backwards. the equation is 0.19=0.05x where x is the cost of the plates and napkins. now all you do is divide both sides by 0.05 to come up with 3.8=x. now that we know the cost of the plates and napkins is $3.80, all we have to do is subtract this cost from the total cost of $8.25 giving us the cost of the watermelon which is $4.45.
