The area of only one base was added. The first term should have a factor of 2.
3x - 17 = 9x + 7
Rearrange on same sides
-17 - 7 = 9x - 3x
-24 = 6x
Divide by 6 on either sides to isolate 6

6 and 6 cancels out
-4 = x
Answer is:
B. x = -4
Answer:
y = At²/755
Step-by-step explanation:
A = 755y/t²
multiply both sides by t²
At² = 755y
Divide both sides by 755
At²/755 = y
Flip
y = At²/755
Answer:
Step-by-step explanation:
Function representing the bacterial growth has been given as,

a). Here 1200 represents the initial number of bacteria taken for the study (1).
b). 1.8 represents the growth factor by which the population of the bacteria is multiplying.
c). Second study is modeled by the function given as,

Here, initial population of bacteria = 1000
Difference in 1200 and 1000 in two studies means → Second study was conducted on 1000 bacteria while in study (1) number of bacteria were 1200.
