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:
L = 80.2 + 2(0.4)
(b) No, one linear equation will be sufficient to solve the problem. Because it is not two statements of equation
Step-by-step explanation:
Between 1996 and 2005, there is 10 years difference.
It is given in the question that the life expectancy increases by 0.4 every five years.
Between 1996 and 2005, life expectancy of woman born will increase by 2x0.4 = 0.8.,
In 2005, the life expectancy of woman born is:
L = 80.2 + 0.8 = 81.0 years
Answer:
point 13 on the line
Step-by-step explanation:
First you would distribute the 2 to the -8 (because of the parenthithese), which would give you -16.
Then you would add the -3 .
So, your answer would be -19. Hope this helps!
Answer:
y = 5x + 4
Step-by-step explanation:
Starting with 5x - y = -4
Subtract 5x from both sides to get -y = -5x - 4
Multiply the entire equation by -1 to make the y positive
You get y = 5x + 4
