Answer:
(-x+4)^3
Step-by-step explanation:
when you turn the x to negtive it filps over the y-axis and if the whole thing is negitve like -(x+4)^3 it filps over the x-axis
C and make sure next time make the pic look cleaer
Answer:
Step-by-step explanation:
Given the data:
Weight ____Height
110 _______ 120
130 _______140
150 _______160
From the data given, we can conclude that that there exist a positive relationship between weight and height. As weight increases, the height increases and vice versa. The weight variable and height variable are positively correlated and thus an individual with a high weight value will have a high height value.
Answer:
= 2
= k(k+1)
= (k+1)(k+2)
Step-by-step explanation:
We are given the statement,
as 2 + 4 + 6 + . . . + 2n = n(n+1)
That is,
as 2 + 4 + 6 + . . . + 2n = 
So, we have,
= 
= 2
= 
= 2 + 4 + 6 + . . . + 2k = k(k+1)
= = 2 + 4 + 6 + . . . + 2k + 2(k+1) = (k+1)(k+2)
Thus, we get,
= 2
= k(k+1)
= (k+1)(k+2)
