My guess would be guess A
Look for "Math Clues." Math Clues are like how many, fewer, left, and more.
How many is the total.
Fewer & Left are subtraction.
More represents add.
Recall that
d/dx sech(x) = - sech(x) tanh(x)
d/dx tan⁻¹(x) = 1/(1 + x²)
Then by the chain rule,
dy/dx = - sech(x) tanh(x) / (1 + x²)
Answer:
(2,4)
Step-by-step explanation:
When graphed the lines intersect at point (2,4) which is the solution.
