Answer:
y = 1
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y =  ← k is the constant of variation
 ← k is the constant of variation
To find k use the condition y = 25 when x =  , then
 , then
25 =  = 5k ( divide both sides by 5 )
 = 5k ( divide both sides by 5 )
5 = k
y =  ← equation of variation
 ← equation of variation
When x = 5, then
y =  = 1
 = 1
 
        
             
        
        
        
The <em>speed</em> intervals such that the mileage of the vehicle described is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h]
<h3>How to determine the range of speed associate to desired gas mileages</h3>
In this question we have a <em>quadratic</em> function of the <em>gas</em> mileage (g), in miles per gallon, in terms of the <em>vehicle</em> speed (v), in miles per hour. Based on the information given in the statement we must solve for v the following <em>quadratic</em> function:
g = 10 + 0.7 · v - 0.01 · v²      (1)
An effective approach consists in using a <em>graphing</em> tool, in which a <em>horizontal</em> line (g = 20) is applied on the <em>maximum desired</em> mileage such that we can determine the <em>speed</em> intervals. The <em>speed</em> intervals such that the mileage of the vehicle is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h].

Y/-2 + 5 = 13
y/-2 = 13 - 5 = 8
y = -2(8) = -16
y = -16
        
                    
             
        
        
        
Answer:
8
Step-by-step explanation:
total number of pencils = 186
number of students = 23
number of pencils each student gets = number of pencils ÷ number of pencils
 
=186/23
=8.08
so each student gets 8 pencils
