-2x – 1 = y
5y + 3x = 9
solve for x and y

(-2,3)

Step-by-step explanation:

(-2,3) hope this helps

Step-by-step explanation:

y=-2x-1

5y+3x=9, using y from above in this equation gives you

5(-2x-1)+3x=9

-10x-5+3x=9

-7x-5=9

-7x=14

x=-2, and since y=-2x-1

y=-2(-2)-1

y=4-1=3, so the solution is the point (-2,3)

x=-2 and y=3

hey i’m new i won’t be answering any questions now bye peeps see you next time

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.
