No se porque no se me van a hacer nada de eso
(x-73) + (x-65) = x
2x - 138 = x
2x - x = 138
x = $138 cost of the bike
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)
Yes because together they have a little more than one and a half feet of wire
9 and 250 thousandths written as a mixed number is as much as 9 250/1000. We can simplify it, so we'll get:
9 25/100
Or even:
<u>9 1/4
</u>
I hope it will help you :)
