80 I think I don’t exactly get what you’re asking tho
Hello!
If Bruce observes that the number of pitches a batter hits varies and is given by the function f(x)=x-11, and the batters get {4, 12, 14, 27, 42}, then Bruce threw {15, 23, 25, 38, 53} pitches. We get this solution set by adding 11 to each element in the set {4, 12, 14, 27, 42}.
Have a nice day
Answer:
The second graph.
Step-by-step explanation:
The first piece of the piecewise function is g(x) = -2x, and it is on the part of the domain defined by x < -2. This means that the point at -2 will not be filled in, since it is strictly less than and not less than or equal to. It also means that the graph will be a line with a slope of -2 from this point backward; this means going backward, the graph will go up two and backward 1.
The second piece of the piecewise function is g(x) = -x². This will be an upside-down parabola (u-shaped graph) that passes through (-1, 1), (0, 0) and (1, -1). It is for the piece of the domain including -2 and going up to but not including 1; this means the left endpoint will be filled in and the right will not.
The third piece of the piecewise function is g(x) = x. This is a straight line with a slope of 1, meaning it goes up 1 and over 1. It is for the part of the domain including 1 and going to the right. This means the endpoint will be filled in.
Answer:
A
Step-by-step explanation:
the answer is A because I got it right on my test
5x + 30x^2 = 57
30x^2 + 5x = 57
30x^2 + 5x - 57 = 0
Using Quadratic Formula
x = 1.297588259
and
x = -1.464254926
