Answer:
dy/dx = 2/x
Step-by-step explanation:
y = In x^2
Let u = x^2
du/dx = 2x
y = In u
dy/du = 1/u
dy/dx = dy/du × du/dx = 1/u × 2x = 1/x^2 × 2x = 2/x
Let n = the unknown number.
Quotient tells you use division.
n/7 = 39
Multiply both sides by 7 to cancel out the number in the denominator and isolate the variable.
n = 39(7) = 273
n = 273
7/8 × 2 = 14/8
14 / 8 = 1.75
17.5 is the Answer
Answer:
K=J+6/2
Step-by-step explanation:
J= -2(3-k)
simplify whats in the bracket
J= -6+2k
J+6=2k
Divide both sides by 2
J+6/2=2k/2
2 and 2 will cancel out
remaining K
So, Therefore K=J+6/2
