1) Option C is correct
2) Option B is correct
Step-by-step explanation:
Question no 1:
We need to find the constant of proportionality
The constant of proportionality can be found by using the formula y/x = k, where k is the constant of proportionality.
Finding k:
x = Hot pepper corn
y = chedder corn
So, y/x = 10/4 = 2.5
y/x = 20/8 = 2.5
y/x= 30/12= 2.5
So, Constant of proportionality is k = 2.5
Hence Option C is correct.
Question No 2
Every female rabbit has 5 baby rabbits. We need to find ratio of baby rabbits to female rabbits.
Baby rabbits = 5
female rabbits = 1
Ratio of baby rabbits to female rabbits: 5: 1 or 5/1 = 5
So, ratio of baby rabbits to female rabbits is 5
Option B is correct.

Answer:
1/4
Step-by-step explanation:
8 divided by 2= 0.25=1/4
The equation
y = mx + c
First let’s find m
m is the gradient
gradient is found with
rise/run
rise is the y run is x
So
y1 - y2 / x1 - x2
Can you do that
Answer:
C. 3x + 2y = 5 and 2y = 6 - 3x & D. 3x = 2 − 4y and 4y = 7 − 3x , have no solution! (:
