Answer:
$0.10/pencil
Step-by-step explanation:
Find the unit cost. To do this, divide $1.25 by 12 pencils, obtaining:
$1.25
---------------- = $0.1042/pencil, or (more logically) $0.10/pencil
12 pencils
MachineA: y=120x
MachineA could pack in 12 min
y=120(12)
y=1440
MachineB could pack in 12 min
y=150(12)
y=1800
MachineB pack than MachineA
1800-1440
=360 candies
Answer:
A
Step-by-step explanation:
The rate of change for the table is found using the slope formula. The rate of change for the linear function is the coefficient of x.
__
<h3>table</h3>
The slope formula tells us the rate of change is ...
m = (y2 -y1)/(x2 -x1)
m = (-9 -(-10))/(-1 -(-4)) = 1/3
<h3>equation</h3>
The coefficient of x in the equations of the offered answer choices are 1/4 and 6.
<h3>comparison</h3>
The relations between the various slopes are ...
1/4 < 1/3 < 6
That is, the equation with a slope of 1/4 has a rate of change less than that of the function represented by the table:
y = 1/4x +4 because ... table of values is 1/3
