we have,

14x+8+6x+12=180 {interior angle}

or, 20x+20= 180

or, 20x= 180- 20

or, x= 160/20

:. x= 8

Now,

14x+8= 14.8+8

= 112+8 =120

6x+12= 6.8+12

= 48+12 = 60

Which number best represents the slope of the graphed line?

kykrilka [37]

Answer:

1/2 or 0.5

Step-by-step explanation:

Hello!

Pick two points on the graph, I'm picking (0,5) and (2,6)

To solve for the slope, we want the ratio to the rise of the graph, over the run of the graph (Rise/Run).

As the graph Rises 1 unit, it also Runs 2 units.

Hence the fraction 1/2.

We can also use the slope formula, given two points : ( $(x_1, y_1) , (x_2, y_2)$

Formula: $\frac{y_2 - y_2}{x_2 - x_1}$

Plug in our points (0,5) and (2,6):

$\frac{y_2 - y_2}{x_2 - x_1}$
$\frac{6 - 5}{2 - 0}$
$\frac12$

The slope is 1/2, or 0.5

Answer:

usually right now for me tax is 13% so when i and then i usually multiply by 1.13 to give me the total which would be the same for you so you need to multiply by 1.07 which is essentially c.

therefore c is the answer

Given the line below. Write the point-slope form of the given line that passes through the points (-4, -1) and (3, -3). Identify

allsm [11]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ -4}} &,&{{ -1}}~) 
% (c,d)
&&(~{{ 3}} &,&{{ -3}}~)
\end{array}
\\\\\\
% slope = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{-3-(-1)}{3-(-4)}\implies \cfrac{-3+1}{3+4}\implies -\cfrac{2}{7}$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-1)=-\cfrac{2}{7}[x-(-4)]
\\\\\\
y+1=-\cfrac{2}{7}(x+4)$
