Answer:
Yes
Step-by-step explanation:
the function that gives the alcohol level is:

where x is the number of hours.
we need to know if after 4 hours an average person is legally drunk, thus:

and we substitute this in the function:

solving these operations we obtain:


the alcohol level after 4 hours is 3.24.
Since a person is considered to be legally drunk if the level exceeds 1.5, and we obtained 3.24 which is greater than 1.5, a person who has been drinking for 4 hours under the conditions indicated by the problem would be considered legally drunk.
Answer:
6.
Step-by-step explanation:
11 + 2k > 19
2k > 19 - 11
2k > 8
k > 8/2
k > 4.
X-Intercept is found by setting y to = 0.
<span>Y-intercept is found by setting y to =0.</span>
7(x+4)>0
Distribute 7. (multiply by x and 4)
7x+28>0
Subtract 28 on both sides.
7x>-28
Divide by 7 into both sides.
x>-4
x>-4 is the answer.
I hope this helps!
