Answer:
cases does he hear per hour.
Step-by-step explanation:
Unit rate is expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.
Given: Jerry hears five cases every two and three eights hours.
⇒ 5 cases for every 
hours
or we can write this as;
For every 
hours he hears 5 cases.
Unit rate per hour = 
cases.
Therefore, he hears cases per hour at this constant rate.
Answer:
-1.5
Step-by-step explanation:
2(-1/4)(3)
= - 1.5
∆= b^2 - 4ac
where b= -2
a=1
c=2
therefore: 2^2 - 4 x 1 x 2
= 4 - 4 x 2
= 4 - 8
= -4
Answer:
there is no solution for these linear equations in two variables.
since a1 (y) = a2 (y)
b1 (5x) = b2 (5x)
but, c1 (12) not equal to c2 (18)
For this case we have the following functions:
By definition we have to:
Substituting:
The range of the function is given by all values of "and" valid. That is, all the real numbers.
