Answer:
The equation of the line will be:

Step-by-step explanation:
Given the points
Finding the slope between (3, 4) and (12, 9)




The equation of the line can be obtained using the point-slope form of the equation of the line

substituting the values m = 5/9 and the point (3, 4)



Therefore, the equation of the line will be:

 
        
             
        
        
        
Answer:
There will be 200 000 bacteria after 8 hours
Step-by-step explanation:
The crop quadruples every hour.
x represents the number of hours that pass after preparing the crop
y represents the number of bacteria after x hours.
The equation for y in function of x  3 hours after observing the crop is:

We want to know after how long there will be 200 000 bacteria.
Then we make y = 200 000 and clear x.

 
        
             
        
        
        
Answer:
x= 17/8
Step-by-step explanation:
6x− 5/2=2x+6
Step 1: Simplify both sides of the equation.
6x+−5/2=2x+6
Step 2: Subtract 2x from both sides.
6x+−5/2−2x=2x+6−2x
4x+−5/2=6
Step 3: Add 5/2 to both sides.
4x+−5/2+5/2=6+5/2 
4x=17/2
Step 4: Divide both sides by 4.
4x/4=17/2/4
x=17/8
 
        
             
        
        
        
Answer:
The answer would be m.
Step-by-step explanation:
The point would be (7,1)  If you look at the top two points, (3,5) and (10,5)  You can see that the y coordinates are the same.  They are both 5.  So on the bottom left (0,1) we know that are n will be 1 .  Now we have to figure out m.  If we look on the top (3,5) (10,5)  We can see from the x's 10 and 3, that they are a distance of 7 apart.  Since our bottom left hand corner is (0,1)  If we add 7 to 0 we get 7.  That makes m equal  7
