You add 7 more to 46 and the answer would be 53.
Answer:
y = 2x + b
I dont know what b is but the slope is 2 I think
Answer:
dy/dx = -b/a cot α
Step-by-step explanation:
x² / a² + y² / b² = 1
Take derivative with respect to x.
2x / a² + 2y / b² dy/dx = 0
2y / b² dy/dx = -2x / a²
dy/dx = -b²x / (a²y)
Substitute:
dy/dx = -b²a cos α / (a²b sin α)
dy/dx = -b cos α / (a sin α)
dy/dx = -b/a cot α
Answer:
5x^2-3x-8
Step-by-step explanation:
So you will want this to be simplified.
expanding brackets is a great way of doing this
one you have expanded all brackets u get the answer above
:)
