1. which of the following is true regarding the graph of y = 1/x ?
a. the domain is all real numbers.
b. there are horizontal and vertical asymptotes.
c. the graph intersects the x-axis in two places.
d. the range is 0 < y< .

b. There are horizontal and vertical asymptotes

Step-by-step explanation:

The graph is a hyperbola with asymptotes of x=0 and y=0

5x+2x=49

7x=49

x=7. 35 apples

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
