1 lap in 2.5 minutes
so 4 in 10 minutes and 12 in 30.
Also 0.4 laps in 1 minute
Answer:
Step-by-step explanation:
4*7+
=28+2*2*2*2
=28+16
=44

Answer:
x>21
Step-by-step explanation:
-2x + 7 < -41 Subtract 7 from both sides
-2x<-48 Divide by negative 2
x>21 When you divide by a negative you have to flip the sign
Answer:
z=-5
Step-by-step explanation:
divide -77.5 by 15.5, which equals -5
The rules that define the piecewise function graphed are as follows:
y = x + 2, y = 5.
<h3>What is a piecewise function?</h3>
A piecewise function is a function that has different definitions, depending on the input.
In this problem, for x between 0 and 3, a linear function is given, with slope given as follows:
m = (5 - 2)/(3 - 0) = 1.
The y-intercept is of 2, as y = 2 when x = 0, hence the definition is:
For x greater than 3, the function is constant at y = 5, hence the definition is:
y = 5, x > 3.
Hence, the rules that are used to define the piecewise function graphed are as follows:
y = x + 2, y = 5.
