When functions are defined by more than one equation, they are called piecewise- defined functions.
Hope that helped
Answer:
see below
Step-by-step explanation:
y = 5x-3
Let x = -2 y = 5(-2) -3 = -10 -3= -13
Let x = -1 y = 5(-1) -3 = -5-3 = -8
Let x = 0 y = 5(0) -3 = 0-3 = -3
Let x = 1 y = 5(1) -3 = 5-3 = 2
Let x = 2 y = 5(2) -3 =10-3 = 7
Answer:
if x=2, y= 1
if x=5, y=-5
Step-by-step explanation:
6x+3y=15
3y=-6x+15
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
y=-2(5)+5
y=-10+5
y=-5
Slope is rise/run
gains 4m height for every 3secons
rise=4m
run=3sec
slope=4/3
if takes 54seconds t
54 times 4/3=72 meters
max height is 72 meteres assuming that it starts from the ground level
