*subtract 5 to the 26 side*
3b=21
Now divide 21 by 3
B=7
So there are 7 books bought. ^^

Answer: -7cos(x)
Step-by-step explanation:
d/dx (f(x))= -7cos(x)
The 3rd option is correct
Answer:
The slope of this line would be undefined.
Step-by-step explanation:
In order to find the slope of any line, use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - -1)/(-6 - -6)
m = (3 + 1)/(-6 + 6)
m = 4/0
Since we cannot divide by 0, then we know the slope is undefined.
