Distribute the -3 to both 2n and 1 (inside the parenthesis)

-3 x 2n = -6n
-3 x 1 = -3

-6n - 3 + 7 = 5

simplify

-6n + 4 = 5

isolate the n

-6n + 4 (-4) = 5 (-4)

-6n = 1

-6n(/-6) = 1(/-6)

n = -1/6

hope this helps

Write an equation in slope-intercept form for the line that satisfies the following condition.passes through (20, 1), parallel t
Dmitrij [34]

Slope-intercept form:  y = mx + b  

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be parallel, they have to have the same slope.

y = 6x + 6    The slope of this line is 6, so the parallel line's slope is also 6.

Now that you know m = 6, substitute/plug it into the equation:

y = mx + b         Plug in 6 for "m" in the equation  

y = 6x + b     To find "b", plug in the point (20, 1) into the equation

1 = 6(20) + b

1 = 120 + b       Subtract 120 on both sides to get "b" by itself

1 - 120 = 120 - 120 + b

-119 = b         Now that you know b = -119, plug it into the equation

y = 6x - 119

Find the sum of the first 30 terms for the given arithmetic sequence.
SOVA2 [1]

Answer:

Step-by-step explanation:

Find the last term of the sequence.

a1 = 8

d = -7

n = 30

a30 = 8 + (n - 1)*(-7)

a30 = 8 + (30 - 1)*-7

a30 = 8 + 29*-7

a30 = 8 - 203

a30 = -195

Sum = (a + L)*n/2

Sum = (8 + -195) * 30/2

Sum = - 187  * 15

Sum = - 2805
