There are 22 students in the class. Make two groups such that the first group has 8 students less than the second one. Let x be the the number of students in the second group.

Equation :

Answer :

6

Step-by-step explanation:

22-8-x

x=22-8

x=14

x=14-8

the temperature will be -18 just do 62 + (-40) + (-40)

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
