so we have a table of values, with x,y coordinates, so let's use any two of those points to get the slope of the table and use the point-slope form to get its equation

~\hspace{2.7em}\stackrel{\textit{let's use}}{\downarrow }\qquad \stackrel{\textit{and this}}{\downarrow }\\\begin{array}{|lr|r|r|r|r|}\cline{1-6}x&0&1&2&3&4\\y&-1&3&7&11&15\\\cline{1-6}\end{array}\\\\[-0.35em]\rule{34em}{0.25pt}\\\\(\stackrel{x_1}{1}~,~\stackrel{y_1}{3})\qquad(\stackrel{x_2}{4}~,~\stackrel{y_2}{15})

\stackrel{slope}{m}\implies\cfrac{\stackrel{rise}{\stackrel{y_2}{15}-\stackrel{y1}{3}}}{\underset{run}{\underset{x_2}{4}-\underset{x_1}{1}}}\implies \cfrac{12}{3}\implies 4\\\\\\% point-slope intercept\begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{4}(x-\stackrel{x_1}{1})\\\\\\y-3=4x-4\implies y = 4x-1\implies \blacktriangleright  y = 4x+(-1)\blacktriangleleft

What is the value of x in the figure shown below?
Zepler [3.9K]

Answer:

75 degrees.

Step-by-step explanation:

The total number of degrees in a triangle is 180 degrees therefore you can take the sum of the other 2 angles in the triangle and take that number and subtract it from 180.

1). 30+75=105

2).180-105=75

3). using the Side, Side, Side geometry rule, this means that both triangles are the same for all angles and side lengths

4). using the Alternative angle rule, the rule that say that a line that intersects 2 parallel lines forms 4 pairs of similar angles

5). therefore angle ABC is the same as angle BCD

6). Angle ABC was determined to be 75 degrees therefore angle BCD is also 75 degrees

PLEASE HELP ME!!!!! brainy to whoever answers correctly! answer all parts please.
zhenek [66]

Answer:

y = -2

Step-by-step explanation:

Since it is a stright line going horizantal we know that its going to be 'y = a number' meaning that for any point of x, y will always be that same number. So if you look at where the line is on the y-axis its at y = -2
