The expression 5(2)^t5(2) t gives the number of leaves in a plant as a function of the number of weeks since it was planted. what does 22 represent in this expression?

2 is growth factor

Step-by-step explanation:

We are given expression

We can use formula

here ,

a is initial value

b is growth factor

so, we get

so, growth factor is 2

So, Number of leaves doubled after one week

So, 2 is growth factor

a. -0.3 > -0.33

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
