PLZZZ HELP NEED ANSWER ASAP

The answer is A: yes, she is correct

Step-by-step explanation:

Roxanne is correct because the solution is where the two lines meet. In this case, systems y = 2/3x-5 and y=-2x+3 intercept at (-3, -3), like Roxanne insisted. Hope this helps!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
