Answer:
6
Step-by-step explanation:
6j + 27 = j + 57
6j - j = 57 - 27
5j = 30
j = 30 / 5
j = 6
Answer:
Domain 
Range
Step-by-step explanation:
Domain : Domain of a function 
is the set of all possible values of 
for which exists.
Range : range of a function is the set of all possible values of .
Here 
can be any value from 
to 
.
hence possible value of can be any value between and
let 
so 
.
hence can have any value between 
.
Range
Those are all lines...
So the x interval is from -2 to 3, because of x=-2 and x=3
The upper line is y(u)=4x and the lower line is y(l)=x-5
So the area between the two lines is:
A=⌠y(u)-y(l) dx
A=⌠4x-x+5 dx
A=⌠3x+5 dx
A=[3x^2/2+5x]
A=[(3x^2+10x)/2], x=[-2,3]
A=(1/2)(27+30-(12-20))
A=(1/2)(57+8)
A=(1/2)(65)
A=32.5 u^2
Step-by-step explanation:
-17 < 3 - 5x
-3 -3 step 1: subtract 3 from both sides
-20 < -5x
/-5 /-5 step 2: divide both sides by 5
4 < x
