Answer:
equation 'b': y = -3/4x + 5
equation 't': y = 4/3x - 2
Step-by-step explanation:
parallel lines must have the same slope
the slope of perpendicular lines must be opposite and reciprocal
Let the speed of car B be x.
Car B is faster than car A 15mph so the speed of car A would be: x-15.
From the problem, we could come up with an equation:
So car B was traveling at 60mph
So, assume she starts at 0. Then, subtract 18, sense she lost 18 points.
She now has -18 points. Part 2, she gained 22, so its -18 + 22, which is 4.
She now has 4 points. Part 3, she gained 4 points, so its 4 + 4, which is 8.

Answer:
a.) f'(x) = 2x - 2
b.) horizontal tangent line at (1, 0)
c.) view image
d.) the point given, (-1, -1/2), isn't even located on the graph of f(x). Either there is a typo or the question is poorly stated.
Step-by-step explanation:
a.) You should know how to do derivative already
b.) Horizontal tangent line just mean that the slope is zero. Since a derivative is a slope, just find when the derivative is equal to 0.
c.) The function f(x) looks like a U. The only spot that has a zero slope is at the bottom of the U when the slope changes from negative to positive. Since my horizontal tangent line(where the slope is 0) is located at point (1,0), that must be where the bottom of the graph is,
d.) Poorly stated question. The point given isn't even located on the graph.
