Answer:
y = -4/3x +4
Step-by-step explanation:
y= mx+b
 solve for y.
4x+3y=12
Step 1: Add -4x to both sides.
4x+3y+−4x=12+−4x
3y=−4x+12
Step 2: Divide both sides by 3.
Let's solve for y.
4x+3y=12
Step 1: Add -4x to both sides.
4x+3y+−4x=12+−4x
3y=−4x+12
Step 2: Divide both sides by 3.
3y / 3 =-4x +12 /3
y = -4/3x +4

Answer:
70
Step-by-step explanation:
Graph it 
 
        
                    
             
        
        
        
First, order the number set from least to greatest: 
3 , 4 , 4 , 7 , 8 , 9 , 12 , 14 , 16 , 20
Mean: You find the mean by combining all the terms, and dividing by the amount of the terms there are in the number set: 
(3 + 4 + 4 + 7 + 8 + 9 + 12 + 14 + 16 + 20)/10
(97)/10 = 9.7
Mean: 9.7
Median: You find the median by first ordering the number set from least to greatest, and finding the middle number. Note that if there is a even number of numbers in the set, you find the mean with the two given median digits: 
8 & 9 are the median numbers: 
(8 + 9)/2 = (17)/2 = 8.5
Median: 8.5
Mode: The mode is the number(s) in the set that shows up the most: 
Mode: 4 (shows up one more time than all other numbers)
Range:  The range can be found by subtracting the least number from the greatest number in the number set: 
Range: 20 - 3 = 17
Range: 17

Answer:
Percent 250 of 275 is 90.9%
Step-by-step explanation:
We have to find 250 is what percent of 275. 
Let X be the percentage, then
=> X =  
Now simplyfying the above relation we get
=> X =  
=> => X = 90.9 %
Hence 250 is 90.9% of 275
 
        
             
        
        
        
1. P = 2(9) + 2(4.5)
P = 18 + 9
P = 27 m
2. P = 5.2(2) + 1.3(2)
P = 10.4 + 2.6
P = 13 ft
3. P = 12.9(2) + 4.7(2)
P = 25.8 + 9.4
P = 35.2 cm
