Answer:
d
Step-by-step explanation:
So the problem states,
52 = 36 + 4x
16 = 4x
x = 4 (must be less than or equal to)
The greatest value is 8, which means n can be either 8 or any number less than 8.
The inequality would be n is less than or equal to 8, which is written as:
n ≤ 8
First of all, you can move the +2x to the other side:
-11 = -26 - 2x
Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
15 = -2x
Then you can divide both sides by 2:
7.5 = -x
Then you can flip the sides and the signs around:
x = -7.5
No, The answer is not -7, it is -7.5
Hope this helps! :)
(a) Using the completing the square method, we need to write into the form of where , so
Expand to find the value of c
Notice that we get back the first two terms, the and the .We need to get rid of the last term of '9' as the term was not in the original form. The final form will look like
Hence,
(b)
(c) , square root both sides plus and minus of 2 Hence
Answer:
the correct answer would be 294 because you would have to divide 126/3 to find out how many miles per hour then multiply it by 7 for 7 hours
