Answer:
1) x³-y³ = (x-y)(x²-xy+y²)
2)x²-y² =(x-y)(x+y)
3)x-y = (x-y)
hcf = (x-y)
lcm = (x-y)(x²-xy+y²)(x+y)= (x³-y³)(x+y)
Step-by-step explanation:
Answer:
Relative frequency method
Step-by-step explanation:
Relative Frequency is a classical approach to probability. It is the ratio of the occurrence of a singular event to the total number of outcomes. This is a tool that is often used after data collection.
In relative frequency, a single part of the data can be compared to the total amount of data collected. This is cleearly observed in the given question.
Answer: 
, where d= distance that Kiran walks in t minutes.
Step-by-step explanation:
Given: Kiran walked at a constant speed.
He walked 1 mile in 15 minutes.
The, distance walked by Kiran in 1 minute = 
mile
The distance that Kiran walks in t minutes = 
miles
If d= distance that Kiran walks in t minutes
The required equation:
Answer:
the number of cakes sell is 5
Step-by-step explanation:
The computation of the number of cakes sold is shown below;
Let us assume
The cake be C
And, the pie cost be P
Given that
There is two types of baked goods sold
The cost of the cake is $4
And, the cost of the pie cost is $64
Now the store sold 9 baked goods for a total of $44
So, the equation would be
C + P = 9
P = 9 - C ...... (1)
4C + 6P = 44............(2)
Now put the value of P in equation 2
4C + 6(9 - C) = 44
4C + 54 - 6C = 44
-2C = -10
C = 5
And, P = 4
hence, the number of cakes sell is 5
Y=1
Y=1 because then it is saying that the line is touching the y axes at 1
