For the graph y= 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. explain your answer with two or more sentences

Parallel: (Horizontal), Perpendicular: (Vertical)

Step-by-step explanation:

The equation y = 1 is an horizontal straight line (). The slope of a line parallel to it is . The slope of line perpendicular to it is , since slope is represented by tangent function, which is undefined at .

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
