Which equation does not belong with the other three?. x+3=-1 x+1=-5 x-2=-6 x-9=-13

beks73 [17]

X+3=-1 => x=-4
x+1=-5 => x=-6
x-2=-6 => x=-4
x-9=-13 => x=-4
So the different one is x+1=-5. Have a nice day!! ^^

Roxana's normal hourly pay is $12

Step-by-step explanation:

overtime pay=p

normal hourly rate=r

p=1.5r

72/4=18

In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment t

GaryK [48]

Using an exponential function, it is found that the mass of the radioactive sample at the beginning of the 13th day of the experiment was of 169.1 mg.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

At the beginning of the first day of the experiment the mass of the substance was 500 grams and mass was decreasing by 8% per day, hence A(0) = 500, r = 0.08, and the equation is given by:

$A(t) = A(0)(1 - r)^t$

$A(t) = 500(1 - 0.08)^t$
