say you were inviting 5 people to fannies you would need to invite 5 1/2 people to get basically the same amount
 
        
             
        
        
        
Answer:I think the answer is 6x because 
18= 6x3
42= 6x7
30= 6x5
Step-by-step explanation:
18= 6x3 
42= 6x7
30= 6x5 And 6x(3x+7x^3+5x^4) it became 18x^2+42x^4+30x^5
 
        
             
        
        
        
Answer:
y=-3x+5
Step-by-step explanation:
concepts: y=mx+b is slope intercept equation formula
m=slope
b= y intercept
Therefore we need to find the slope and y intercept
first find slope
m=
let y2 be 2
let y1 be -4
let x2 be 1
let x1 be 3

6/-2 = -3
m=-3
slope is -3
y= -3x+ b
we need find y intercept now
just plug in (1,2) into that equation
2=-3(1)+b
b=5
y=-3x+5
 
        
             
        
        
        
Answer:
the answer should be x= -7 hope this helps!
 
        
             
        
        
        
You need to use the distance formula 


so the distance between points (5,-2) and (-3,8) is 

which won't simplify so it stays as is
