Answer:
<u>x=-1.5</u>
Step-by-step explanation:
To solve for x, you need to rearrange so the x is on one side of the "=" by itself.
So To do that, first you need to subtract 1/4 on both sides of the "=". This leaves you with 1/2+x=-3/4-1/4. You can simplify the -3/4-1/4 to -1 (-4/4). So, you now have 1/2+x=-1.
The next step is to subtract 1/2 on both sides of the "=". This leaves you with x=-1-1/2. Again, you can simplify the -1-1/2 to -3/2 which can be written as -1.5. So, you now have x=-1.5, which is the final answer.
The question may ask you to write your answer in the form of a fraction, in which case your answer x=-3/2. If the questions wants it written as a mixed number, your answer would be -1 1/2.

Answer:
4 seconds
Step-by-step explanation:
using the vertex formula of a quadratic,
, where (h,k) is the vertex
h is height and t is time in seconds
the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)
Height of 1/2
time of 2 seconds
it will take 2 additional seconds to reach the water again.
this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.
Answer:
it's D all of the above
Step-by-step explanation:
.......
The unit ton, or metric ton, is a non-SI unit but commonly used in the United States. It is both approved by the NIST and the U.S National Institute of Standards and Technology. The equivalence is, 1 metric ton is equal to 1,000 kilograms. So, a metric ton is a thousand times bigger than a kilogram.
Answer:
I believe it’s the third answer!
Explanation:
The domain is what x values there can be, and the relation is between -4 and 4.
