What are the coordinates (x, y) at which the graphs of 2x + 3y = 12 and 2x - y = 4 intersect?
a. (3, 2)
c. (1, -2)
(2,3)
d. (-3, 6)
Letter answers only pls.

  The coordinates (x,y) are (3,2), If the graphs of and are intersect.

Step-by-step explanation:

The given is,

                                         .................................(1)

                                           ....................................(2)

Step:1

            The values of x and y are obtained by elimination method,

            Substrate the equation (1) and (2),

             ( - )

             Equation becomes,

            From the equation (1),

Step:2

            Check for solution,

                                          ....................................(2)

            Substitute the values of x = 3 and y = 2 in above equation,

           Both sides are equal, so the x = 3 and y = 2 is correct answer

Result:

          The coordinates (x,y) are (3,2), If the graphs of and are intersect.

146 days

step-by-step explanation:

1. (365*2)/5 =

730/5 =

146 days

2. 365/5=

73*2   = 146

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
