Answer:
Step-by-step explanation:
We can find the inequalities whether they are valid for x = 5 or not.
if 4x - 1 ≤ 19
Then for x = 5 ⇒ 4 × 5 - 1 ≤ 19
20 - 1 ≤ 19
19 ≤ 19
Since 19 = 19 so inequality is true for x = 5
Now 4x - 1 < 19 for x = 5
4 × 5 - 1 < 19
20 - 1 < 19
19 < 19
It's not valid because 19 is not less than 19 .
Because its less than or equal to 19 and the other is just less than

If u and v are indeed vectors,
,
$12 x .20 = $2.40
12 - 2.40 = $9.60
$9.60 x .07 = $0.67
$9.60 + $0.67 = $10.27
Total price (including tax): $10.27
