Please help & explain PLEASE

A. y = 4.5x

Step-by-step explanation:

y is the length of the fish and x is the time, by checking each equation with values in the table you can see that this is the one that represents the relationship.

Example using (4 yrs, 18 cm):

A: 18 = 4.5(4) ✅

B: 4 = 4.5(18) ❌

C: 4 = 9(18) ❌

D: 18 = 9(4) ❌

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

yes   because as the functions are graphed they eventually will intersect unless otherwise
