Can someone please help

Step-by-step explanation:

Te equation of line is:

y = 3x + 12

Plug x = 0 in the above equation of line, we find:

y = 3*0 + 12

y = 0 + 12

y = 12

y-intercept = (0, 12)

Plug y = 0 in the equation y = 3x + 12

0 = 3x + 12

-3x = 12

x = 12/(-3)

x = - 4

x-intercept = (-4, 0)

Distance between x-intercept and y--intercept

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)

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
