The length of sere's pencil is given by the equation y=15 - x where y is its length in cm and x is the number of days she uses it. a)Find the length of her pencil on day 6.

b) on what day is her pencil 5cm long?

a) Find the length of her pencilonday 6

Step-by-step explanation:

here is the

mark brainliest pl

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
