ANSWER- 23 , 76
Explanation- just did it :)
Set it up at 425=.17x
Solve for x by dividing both sides by .17 to get x=2500
Answer is 2500
The x values decrease by 12 and the y increase by 4.
Answer: (x-12, y+4)
Answer:
25/56
Step-by-step explanation:
make 3 1/8 an improper fraction then u should get 25/8 and then multiply the numerator of 1/7 by 25 and then multiply the denominators of the two fractions to get 7*8=56 so your fraction is 25/56
For simplicity, dy/dx means f'(x);
We have y = ( 8 - x^2 ) / 2x;
Then, y = 4/x - x/2;
So, f'(x) = (4/x - x/2)' = (4/x)' - (x/2)' = -4/(x^2) -1/2 because we use <span> d<span>ifferentiation formulas, such as : (f+g)' = f' + g'; (cf)' = cf'; x'=1; (1/x)' = -1/(x^2);
</span></span>Finally, f'(4) = -4/16 -1/2 = -4/16 - 8/16 = -12/16 = -3/4.
The correct answer is E.
