Question

20. Today is Rini's birthday. Mama is making a beautiful cake for her. Rini wants to learn from her
mother. Mother is very happy. She takes a cup and some eggs. She said the number of eggs needed to
make a cake varies directly as the number of cups of flour used. She takes 2 cups of flour and a half a
dozen eggs. As number of guests increase, the number of eggs and cups of flour increase. Take 'x' as
the number of cups of flour used and 'y' as the number of eggs.
(a) Write an equation for the above relationship.
(i) y = 3x (ii) y = 2x (iii) y = 6x
(iv) y = x
(b) How many eggs are needed if you take 3 cups of flour?
(i) 7 eggs (ii) 8 eggs
(iii) 9 eggs
(iv) 5 eggs
(c) How many cups of flour needed if Rini takes 21 eggs?
(i) 7 cups
(ii) 8 cups
(iii) 9 cups (iv) 6 cups
(d) Will the point (2,6) lie on the graph y = 3x?
(i) always lie (ii) never lie
(iii) may lie
(iv) may or may not lie
(e) If (1,3) is solution of the equation y - 3x = 0, then the graph of this equation
(i) passes through the origin. (ii) is parallel to the x-axis.
(iii) is parallel to the y-axis. (iv) lies on the graph.​

plz answer fast if u i will give I as brillianist

Answer 1

Answer:

(a). y=2x.

(b). 9 eggs.

(c). 7 cups.

(d). maybe

Step-by-step explanation:

(a). an equation y=2x

(b).

2 cups =half dozen eggs

2cups = 6eggs

1cup= 3eggs

so,3cups =9 eggs

(c).

1cup=3eggs

21eggs= 7cups
