Somebody please help meeeee pt.2

rosijanka [135]

Answer:

See explanation

Step-by-step explanation:

Consider the sequence 10, 6, 2, -2, -4, ...

Rewrite it as

$a_1=10,\\ \\a_2=6,\\ \\a_3=2,\\ \\a_4=-2,\\ \\a_5=-6,...$

The points on the coordinate plane are

$(1,a_1),\ (2,a_2),\ (3,a_3),\ (4,a_4),\ (5,a_5),...$ (see attached graph).

Since

$4=a_2-a_1=a_3-a_2=a_4-a_3=a_5-a_4=...,$ given sequence is arithmetic.

If B is the midpoint of AC, and AC = 8x – 20, find BC. 3x - 1 A B C

sammy [17]

Answer:

x = 9

Step-by-step explanation:

Since B is the midpoint, that means segment AB has to be the same length as BC.

Therefore:

$2(3x-1)=8x-20$

$6x-2=8x-20$

$18=2x$

$9=x$

WARRIOR [948]

Answer:

y=2x+7

Step-by-step explanation:

Use point slope form --> $y-y_1=m(x-x_1)$

y-1=2(x+3)

y-1=2x+6

y=2x+7
