2r+ 17= 25
Subtract 17 from each side.
2r= 8
Divide each side by 2

Answer:
(4;-1)
Step-by-step explanation:
2x-2=x²-x-6
x²-3x-4=0
x=4,y=-1
Answer: B) It is the product of the initial population and the growth factor after d days.
Step-by-step explanation: Given initial number of bacteria = 10.
Rate of increase = 20% each day = 0.2 .
Expression for finding the number of bacteria after d days is given by
, where d is the number of days.
We can see than initial population of bacteria is 10 and 10 is being multiplied with growth factor (1 + 0.2) after d days.
Therefore, correct option is B option.
B) It is the product of the initial population and the growth factor after d days.
I believe it’s C sorry if I’m wrong
Answer:
They are proportional
Step-by-step explanation:
Proportionality:
They are proportional because the cost is going up by 10 the entire time and the hours rented is going up by 2 the entire time.
Graphing:
Go to the 2 on the x-axis (horizontal line)
Go up to the 20 on the y-axis (vertical line)
The points to graph are:
(2,20)
(4,30)
(6,40)
(8,50)
I put a pic of what your graph should look like below!
