Replace n with 13 and simplify

an = 84+(n-1)*(-6)
a13 = 84+(13-1)*(-6)
a13 = 84+(12)*(-6)
a13 = 84+(-72)
a13 = 84-72
a13 = 12

Answer: Choice A) 12

What is the equation of the line in the following graph? 1)y=x+2
Levart [38]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (2, 0) and (-2, -4). Substitute:

m=\dfrac{-4-0}{-2-2}=\dfrac{-4}{-4}=1

Therefore we have the equation of a line

y=1x+b\to y=x+b

Put the coordinates of the point (2, 0) to the equation:

0=2+b     <em>subtract 2 from both sides</em>

-2=b\to b=-2

Answer: \boxed{y=x-2}\to\boxed{3)}

The value 13 is 200% of
tia_tia [17]
This would be in terms of dividing the largest number (being 13) by the percentage in decimal form.

The percentage worked where you take that and divide by 100 to get your percentage, meaning:

13/2 = 6.5 | 13 is 200% of 6.5. Because if you double it you get 13 which is how 200% works.

I hope this helps, have a great rest of your day! ^ ^
