7. Madeline has a headache and takes 500 milligrams of a pain reliever. The brand of pain reliever she takes has a half-life of 2.5 hours. Which function could be used to describe the amount of pain reliever remaining in Madeline's system at any given time? F(x) = 500.1 O f(x). x= = 3(500) * O F(x) = 5 * 500 o = F(x) = 500 ()​

its adding 5.5 each time

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
