Roes bushes cost $5 and tomato plant cost $2. write an expression that represent the show the total cost for any number of rose bushes and tomato plant

Expression that represent the show the total cost for any number of rose bushes and tomato plant is:

Solution:

Let "x" be the number of roses bush

Let "y" be the number of tomato plant

Cost of 1 rose bush = $ 5

Cost of 1 tomato plant = $ 2

To find: Expression that represent the show the total cost for any number of rose bushes and tomato plant

Total cost = number of roses bush x Cost of 1 rose bush + number of tomato plant x Cost of 1 tomato plant

Thus the expression is found where, x and y are the number of rose bush and tomoato plant bought respectively

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
