Step-by-step explanation:

Absolute value function:

  • |x| = x when x >= 0.
  • |x| = -x when x < 0.

Swim 3 feet under water => |-3|

Stand 20 feet above => |20|

Using the absolute value function,

we have |-3| = 3 and |20| = 20.

Since 3 is less than 20, |-3| < |20|. (C)

Which of the following function pairs are inverses? Options and questions below:
kolbaska11 [484]

Answer:

Second choice

Step-by-step explanation:

To find inverses, we follow the steps:

1. exchange variables x and y

2. solve for y in terms of x.

The resulting function is the inverse.

Take case 2 as an example:

f(x) = y = 2x-3

1. exchange x and y : x=2y-3

2. solve for y: x+3=2y => y=(x+3)/2 = g(x)

Since the inverse of f(x) is g(x)=(x+3)/2, the second choice is the answer.

Can you please answer this?
Sophie [7]

Answer:

  A. (1, -1)

  B. (1, -1), (2, 0)

  C. x = 0

Step-by-step explanation:

A graph is a plot of all the points that are solutions to an equation.

<u>Part A</u>:

A point will be a solution to two equations if it is a point of intersection of their graphs. The one point that is a solution to both p(x) and g(x) is the one point where their graphs intersect: the red and blue lines cross at (1, -1).

__

<u>Part B</u>:

<em>Any other point on the graph p(x)</em> will be another solution of it. One that is near to the point of intersection with g(x) is the point where p(x) crosses the x-axis: (2, 0). Of course, the solution listed in Part A is also a solution to p(x).

__

<u>Part C</u>:

The point where the graph of g(x) crosses the graph of f(x) is (0, 3). The x-value that makes g(x) = f(x) is x=0. That is the solution to this equation. (We don't really care what the values of f(0) and g(0) are--just that they are equal.)

Which are the correct measures for
-BARSIC- [3]

Answer:

option c is the correct answer

Step-by-step explanation:

∠YXZ+117°=180°

∠YXZ=180°-117°

∠YXZ=63°

63°+36°+∠YZX=180°(sum of angles is 180)

99°+∠YZX=180

∠YZX=180-99

∠YZX=81

Derive the equation of the line that goes through (−3, 1) and (0, −5).
Oksanka [162]

Answer:

C)  y = -2x - 5

Step-by-step explanation:

\sf let \ (x_1,y_1)=(-3,1)\\\\let \ (x_2,y_2)=(0,-5)

\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-5-1}{0-(-3)}=-2

Point-slope formula: \sf y-y_1=m(x-x_1)

\sf \implies y-1=-2(x-(-3))

\sf \implies y=-2x-5
