Please help with this! I need to discern whether or not they represent a function.

A function associates a value from a set (domain) one and only one value from another set. IE, from the same x value you can have only one y. So pick a ruler and scan each graph parallel to the Y axis. If you touch the blue line in two points, that's not a function.

Which equation correctly shows how to determine the distance between the points (9,-2) and (6.3) on a coordinate grid?
Nastasia [14]

Answer:

d = \sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }

Step-by-step explanation:

The distance formula is d= \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}     }.

6 is x_{2}, 9 is x_{1}, 3 is y_{2}, and -2 is y_{1}.

When you plug these into the formula, you get d = \sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }

Write and solve an equation to find the unknown side length x (in feet).
Setler79 [48]

Answer:

11.9 feet

Step-by-step explanation:

We want to find the value of 'x' and we are asked to set up an equation to find the value of x. In equation we must remember to get all the numerical values to one side and all the non-numerical values to the other while remembering to keep the equation balanced for example if we add 4 on one side we must do it to the other side to keep the equation balanced so,

→ x + 5.2 + 11.1 + 6.4 = 34.6

⇒ Simplify equation

→ x + 22.7 = 34.6

⇒ Minus 22.7 from both sides to isolate x

→ x = 11.9 feet

Please answer one question asap <br>A(-4,3) B(2,-1) D(-4,-1) C(2,-5)
Leni [432]

Answer:

Step-by-step explanation:

Vertices of the given quadrilateral are A(-4, 3), B(2, -1), C(2, -5) and D(-4, -1)

Since, slope of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

Slope = \frac{y_2-y_1}{x_2-x_1}

Slope of AB = \frac{3+1}{-4-2}

                    = -\frac{2}{3}

Slope of AD = \frac{3+1}{-4+4}

                    = Not defined (Parallel to y-axis)

Slope of DC = \frac{-5+1}{2+4}

                     = -\frac{2}{3}

Slope of BC = \frac{-1+5}{2-2}

                   = Not defined (Parallel to y-axis)

Slope of AB = slope of DC = -\frac{2}{3}

Slope of BC = slope of AD = Not defined (parallel to y-axis)

As per property of a parallelogram,

"Opposite sides of a parallelogram are parallel and equal in measure"                  

Therefore, ABCD is a parallelogram.
