Answer:
Sanchez bought 20 books.
Step-by-step explanation:
Represent the total number of books purchased by t. Then:
0.75n = 15. Thus, n = 20.
Sanchez bought 20 books.
Answer:
P(x) =
+ 304x - 8510
x = 37 smallest B.E.P
Step-by-step explanation:
P = R - E
P = + 317 x
E = 13x + 8510
P = + 317 x - 13x - 8510
P(x) = + 304x - 8510
B.E.P.(X) where R=E
+ 304 x - 8510 = 0
2(x-37)(x-115)
11 / 3 = 55 / 15;
2 / 5 = 6 / 15;
So. 11 / 3 - 2 / 5 = 55 / 15 - 6 / 15 = 49 / 15 = 3.26 kg is the mass of biscuits left.
Answer:
(x+2)/(x-6)(x+2)
Step-by-step explanation:
We know that vertical asymptotes are found in the denominator, so we can start with 1/(x-6)
x-6 will equal zero at 6, so that is where the VA will be.
For the removable discontinuity (hole), it needs to cancel out in the numerator and denominator. (x+2)/(x-6)(x+2)
when x equals -2, there is an undefined y value.
