8. Solve this system of equations
4x − 2y + 3z = 1
x + 3y − 4z = −7
3x + y +2z = 5
Select the appropriate response:

A) x = − 1, y = 2, z = 3
B) x = − 1, y = 4, z = 4
C) x = − 3, y = 2, z = 3
D) x = − 1, y = 4, z = 3

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.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

answer: it is 8

step-by-step explanation:
