<span>y = –2x + 5
–5y = 10x + 20
replace </span>y = –2x + 5 into –5y = 10x + 20
–5( –2x + 5 ) = 10x + 20
10x - 25 = 10x + 20
-25 = 20...can't be...
answer is <span>D. no solution</span>
Answer:
y = -1x + 5
Step-by-step explanation:
YX equals +2 squared minus -17 is approximately the answer of the origin
Assuming you typed this correctly, and how you wanted it, then the answer(s) would be x=3, or x=8. Both answers are correct. If it were multiple choice, then the answer would look something like: X=3 or 8.
If you meant 2x, then the answer would be x=8/3. This is a fraction



Stationary points occur where the derivative is zero. The denominator is positive for all

, so we only need to worry about the numerator.


for all

, so we can divide through:

But

for all

, so this function has no stationary points...
I suspect there may be a typo in the question.
