Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and
nevsk [136]

Step-by-step explanation:

Points are (8,5) and (-12,-9)

The equation of a line passing through two points is given by :

y-y_1=m(x-x_1)\ \text{m is slope}\\\\y-5=\dfrac{y_2-y_1}{x_2-x_1}(x-8)\\\\y-5=\dfrac{-9-5}{-12-8}\times (x-8)\\\\y-5=\dfrac{7}{10}\times (x-8)\\\\10y-50=7x-56

or

-50+56=7x-10y\\\\7x-10y=6

But he writes the equation 7x – 10y = 3 which is not matching with the one we have calculated. It means that model calculated by Devon is not good.

What is the sum of the first five terms of a geometric series with a1=20 and r=1/4
IrinaK [193]
The sum of a geometric sequence is:

s(n)=a(1-r^n)/(1-r), a=initial term and r=common ration so

s(n)=20(1-0.25^n)/(1-0.25)

s(5)=20(1-0.25^5)/(0.75)

s(5)=26.640625
