So in the photo i’m showing the process you just need to get k by itself, what you do to one side of the equals sign you must do to the other
Answer:
(5,30)
Step-by-step explanation:
That is the constant change in the y's as the x's increase by 1?
12 - 6 = 6
18 - 12 = 6
24 - 18 = 6
The common difference is 6 so the next coordinate will be 6 more on the y and 1 more on the x.

Answer:
At the time measurement starts i.e. initially there was no rainfall i.e. y value is zero.
Step-by-step explanation:
y, in terms of time the rain fell, x.
Now, x is measured in hours after 12 : 00 P.M., with x = 0 corresponding to the time 12 : 00 P.M.
Therefore, the ordered pair (x,y) ≡ (0,0) means that at the time measurement starts i.e. at 12 : 00 P. M. there was no rainfall i.e. y value is zero. (Answer)
Answer:
Dy/Dx=1/√ (2x+3)
Yeah it's correct
Step-by-step explanation:
Applying differential by chain differentiation method.
The differential of y = √(2x+3) with respect to x
y = √(2x+3)
Let y = √u
Y = u^½
U = 2x +3
The formula for chain differentiation is
Dy/Dx = Dy/Du *Du/Dx
So
Dy/Dx = Dy/Du *Du/Dx
Dy/Du= 1/2u^-½
Du/Dx = 2
Dy/Dx =( 1/2u^-½)2
Dy/Dx= u^-½
Dy/Dx=1/√ u
But u = 2x+3
Dy/Dx=1/√ (2x+3)
