Step-by-step explanation:
Answer:
d
Step-by-step explanation:
Answer:
a=1, b=-6, c=2, d=1
Step-by-step explanation:
You are given the function
Find the derivative:
The curve has a tangent line when x = 0 with equation y = 2x + 1, so
Hence,
The curve has a tangent line when x = 1 with equation y = -3x + 2, so
So,
From the second equation, a=-5-b, substitute it into the first one:
Answer:
F⁻¹(x) = x/9
Step-by-step explanation:
To find the inverse of a function, you want to switch x and y in the equation and solve for y.
F(x) = 9x
x = 9F(x)
x/9 = F⁻¹(x)
Therefore, the inverse is F⁻¹(x) = x/9.
Answer:
Carmen's score is 75 strokes.
Linda's score is 81 strokes.
Step-by-step explanation:
Let the score of Linda be "x".
<em>It is given that Carmen's golf score is 6 strokes less than Linda's.</em>
Thus, Carmen's score is (x-6).
The total score of the girls is
=
The total score is given to be 156.
Thus, the equation becomes,
<em>Thus Linda's score is 81 and Carmen's score is (156-81) 75.</em>
