Step-by-step explanation:
The formatting is likely incorrect for these two options:
y=(x−1)2, and
y = ( x − − 1 ) 2
I'll assume they were meant to be:
y=(x−1)^2, and
y = ( x + 1 )^2
In this case they would be non-linear, since y depends on the value of 
Use a "^" sign to indicate raised to a power: x^2 means
.
y=(x−1)2 means y = 2x - 2
y=(x−1)^2 means y = 
Answer:
£90
Step-by-step explanation:
Given the ratio of 5:1, total denominator is 5+1=6. Therefore, Natasha's proportion is 5/6 while Richard gets 1/6.
The differences in proportion is 5/6-1/6=4/6
This difference of 4/6, simplified as 2/3 is equivalent to £60
Therefore, 3/3=1 is given by cross multiplication
Total proportion is £60*3/2=£90
In this case, Natasha gets 5/6 of 90=5/6*90=75 while Richard gets 1/6 of 90=1/6*90=15
The difference is 75-15=60
In concljsion, they altogether get £90
