In the figure below A, E,F and C lie in plane X. Points B and D do not lie in plane X. For each part below, fill in the blanks to write a true statement

Step-by-step explanation:

(a). B, C and D are the distinct points that are collinear.

(b). FC and BD are the distinct lines that intersect each other at a point C.

(c). E, F, C and A are the points that are coplanar (on the same plane).

(d). Another name for plane X is plane AEF. (Since a plane is defined by the three distinct points on the same plane.

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.
