Geoff says that changing the value of m while leaving b unchanged in f(x)=mx+b has no impact on th intercepts of the graphs. marcus disagrees with this statement. who is correct? explain your reasoning.

Marcus is correct, changing the value of m and leaving b unchanged has impact in the x-intercept.

Step-by-step explanation:

The linear equation is

f(x) = m*x + b

now, m is the slope and b is the y-intercept, so if we cahenge m, b remains unchanged, so the y-intercept does not change.

now, the x-intercept is when f(x) = 0 = m*x + b

so the x-intercept is = -b/m

We can see that the x-intercept depends inversilt with m, so chaging m will change the x-intercept.

step-by-step explanation:

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)
