1. What does the equation y = 9 represent in R3? a. a point b. a line c. a plane d. a circle 2. What does z = 2 represent? a. a point b. a line c. a plane d. a circle 3. What does the pair of equations y = 9, z = 2 represent? In other words, describe the set of points (x, y, z) such that y = 9 and z = 2. a. a point b. a line c. a plane d. a circle

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
