(9, 19) (2, 16)<br> Write the coordinates as decimals or integers.
9966 [12]

Answer:

In decimal 0.428571428

Step-by-step explanation:

The slope = (y2 - y1)/(x2 - x1) y2 = 16, y1 = 19x2=2 and x1=9

The slope = (16 - 19)/(2 -9)

The slope = (-3)/(-7)

The slope = 0.428571428

So in decimal form the coordinates are going to be written as 0.428571428

Slope is the steepness of a line, it is the difference between the y coordinates divided by the difference in x coordinates.

PLEASE HELP ME, ILL BRAINLIEST YOU ill give u 30 points if you help
lisov135 [29]

Answer:

x = 58

y = 90

Step-by-step explanation:

  • This is a rhombus becuase it a quadralterial and it has four right triangles, and it diagonals bisect each others so it cant be a trapezoid, and paralleolgram. and it doesnt have four right corner angles so it cant be a square or rectangle or kite.

A rhombus inner angle measure is 90 degrees.

So

y = 90

This means the upper left angle of the top triangle measure is 58 becuase triangle interior theorem.

Since a rhombus bisects angles, angle x measure 58.

You lose an online auction for an autograph. Your losing bid of $28 is 40% of the winning bid. How much less was your bid than t
TEA [102]

Answer:

My bid was $42 less than the winning bid.

Step-by-step explanation:

The winning bid is x.

$28 is 40% of x

0.4x = 28

x = 28/0.4

x = 70

The winning bid was $70.

$70 - $28 = $42

Answer: My bid was $42 less than the winning bid.

The rate of change in the function y=x+4 is________ the rate of change of the function represented in the table.
Snezhnost [94]
Recall that the slope is the "average rate of change" of any function.

\bf y=\stackrel{slope}{1}x+4\qquad \qquad &#10;\begin{array}{ccll}&#10;x&y\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;0&6\\2&8\\4&10\\6&12&#10;\end{array}&#10;\\\\\\&#10;\textit{let's check what is the slope of the tabled function}\\&#10;\textit{by using two points from it}

\bf \begin{array}{lllll}&#10;&x_1&y_1&x_2&y_2\\&#10;%   (a,b)&#10;&({{ 2}}\quad ,&{{ 8}})\quad &#10;%   (c,d)&#10;&({{ 6}}\quad ,&{{ 12}})&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope = {{ m}}= \cfrac{rise}{run} \implies &#10;\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{12-8}{6-2}\implies \cfrac{4}{4}\implies 1
