Answer:
Jason can plug what x equals (6.5) back into the equation everywhere x is and solve! If the answers on both sides equal each other (example 3=3) then that means his answer is correct.
Step-by-step explanation:
Facts and math.
Answer:
You begin with 1 bacteria, and after 1 hour it has tripled so you now have 1 x 3=3.
Next hour, it triples again so you now have 1 x 3 x 3=9
You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 34 means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).
Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:
n x 324 where n is the number of bacteria you begin with.
Since you begin with 1 bacteria, the solution is 1 x 3 to the power 24 and u will get ur answer

Option C ![-7x-5y=-48](https://tex.z-dn.net/?f=-7x-5y%3D-48)
Step-by-step explanation:
step 1
Find the slope of AB
we have
A(-3,-1) and B(4,4)
The slope m is equal to
![m=(4+1)/(4+3)](https://tex.z-dn.net/?f=m%3D%284%2B1%29%2F%284%2B3%29)
![m=5/7](https://tex.z-dn.net/?f=m%3D5%2F7)
step 2
Find the slope of BC
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so
![m1*m2=-1](https://tex.z-dn.net/?f=m1%2Am2%3D-1)
we have
![m1=5/7](https://tex.z-dn.net/?f=m1%3D5%2F7)
substitute
![5/7*m2=-1](https://tex.z-dn.net/?f=5%2F7%2Am2%3D-1)
![m2=-7/5](https://tex.z-dn.net/?f=m2%3D-7%2F5)
step 3
Find the equation of the line into slope point form
![y-y1=m(x-x1)](https://tex.z-dn.net/?f=y-y1%3Dm%28x-x1%29)
we have
![m=-7/5](https://tex.z-dn.net/?f=m%3D-7%2F5)
![B(4,4)](https://tex.z-dn.net/?f=B%284%2C4%29)
substitute
![y-4=-(7/5)(x-4)](https://tex.z-dn.net/?f=y-4%3D-%287%2F5%29%28x-4%29)
Multiply by 5 both sides
![5y-20=-7x+28](https://tex.z-dn.net/?f=5y-20%3D-7x%2B28)
![7x+5y=28+20](https://tex.z-dn.net/?f=7x%2B5y%3D28%2B20)
![7x+5y=48](https://tex.z-dn.net/?f=7x%2B5y%3D48)
Multiply by -1 both sides
![-7x-5y=-48](https://tex.z-dn.net/?f=-7x-5y%3D-48)
Multiply 40.5 by 800
you get 32400
then divide by 100 to get to meters
324 meters
