There's a special case of the quadratic formula called the Shakespeare Quadratic Formula (2b or -2b) that applies when the linear coefficient is even.
If you're planning on solving a lot of quadratic equations quickly, it's good to know.
Here we have
so
Answer:
11/50
Step-by-step explanation:
you talk 22 and divide it by 2 & you get 11
then you take 100 and divide it by 2 and you get 50
1. -1/3 - (-1/2) = .16666666666666
2. -8
Hope it helps, if you need it in fractions, you can always convert it :)
The answer to the question is $4.7
Answer:
-38 - 12x < 200
Step-by-step explanation:
Given,
The original elevation = -38 feet,
Also, the explorer starts moving at a rate of negative 12 feet per minute.
So, the distance covered by explorer after x minutes = -12x feet,
Thus, the final elevation = original elevation + distance covered by explorer
= -38 - 12x
According to the question,
final elevation < -200 feet
⇒ -38 - 12x < 200
Which is the required inequality.
