Answer:
f9
Step-by-step explanation:
Answer:
f'(-1)= 3
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)= (7-(-2))/(1-(-2))=9/3=3
Slope of the tangent line in the given point equals f' at this point.
So,
f'(-1)= 3
Answer: 0.75 ×24 carat = 18 carat
Step-by-step explanation:
24 carat is 100% pure gold. If there is 3/4 parts of gold it is 75 % = 0.75
C. 16 over 26
8/18 x 2/2 = 8 x 2 is 16 and 18 x 2= 26 so your answer is 16/26 (multiply the top and bottom by a number that is the same to get a proportional fraction)
