$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 6 &,& -2~) 
% (c,d)
&&(~-3 &,& 7~)
\end{array}
\\\\\\
% slope = m
slope \implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{7-(-2)}{-3-6}\implies \cfrac{7+2}{-3-6}\implies \cfrac{9}{-9}\implies -1$

Find the sum: (3x2 + 5x − 8) + (5x2 − 13x − 5)

Trava [24]

The given expressions are $3x^{2}+5x-8$ and $5x^{2}-13x-5$

We have to find the sum of the given expressions,

$(3x^{2}+5x-8)+(5x^{2}-13x-5)$

Combining the like terms of both the expressions, we get

$(3x^{2}+5x^{2})+(5x-13x)+(-8-5)$

= $8x^{2}-8x-13$ .

The initial number of veiws for a reader board was 25. The number of views is growing at a rate of 18% per week.

Ugo [173]

Based on the given values above, we will be able to determine the expected number of viewers after four weeks by just multiplying the number of viewers to 18% per week. So the initial is 25 for this next. So for the first week, additional of 4.5 viewers. So the total would be 29.5 Second week, additional of 5.31, and the total would be 34.81. Third week, additional 6.27, the total would be 41.08. And on the fourth week, additional of 7.39, so the expected number of viewers would be 48.47. To round this off to the nearest whole number, we can get 48 viewers. Hope this helps.
