The slope is undefined because you need a y intercept as well.
Answer:
1.14 days (approximately)
Step-by-step explanation:
Family drives 350 miles per day
Let d = days
Equation: 350d = 400
d = 400/350
d is approximately 1.14 days
If you want to answer it without decimals, you should say around 2 days since it's going to take more than one day to travel.
Answer:
x ≥ 21.5/19
Step-by-step explanation:
-1.5(4x + 1) ≥ 45 - 25(x + 1)
-6x - 1.5 ≥ 45 - 25x - 25
-6x + 25x ≥ 45 - 25 + 1.5
19x ≥ 21.5
x ≥ 21.5/19
