2(-2×-8)+4×=2(1+3×) someone pls help​
Murljashka [212]

Answer:

x=-3

Step-by-step explanation:

2(-2x-8) + 4x = 2(1+3x)

Distribute:

-4x-16+4x=2+6x

Simplify Like-Terms:

-16=2+6x

Subtract 2 from both sides:

-18=6x

Divide both sides by 6:

x=-3

64,-48, 36, -27
Ganezh [65]

Answer:

Step-by-step explanation:

The first term of the given sequence is a(1) = 64.  Each succeeding term is found by multiplying the present one by (-3/4), and so (-3/4) is the common ratio.  Then the geometric sequence represented here is

a(n) = a(1)*(-3/4)^(n - 1), or, specifically,

a(n) = 64*(-3/4)^(n - 1)

Alternatively:  a(n) = a(n - 1)*(-3/4). or a(n) = (-3/4)a(n - 1)

CAN SOMEONE ANSWER ASAP 20 POINTS AND ILL GIVE YOU BRAINLIST
9966 [12]

Answer:

First, fourth.

Step-by-step explanation:

The g(x) function is basically g(x) = (x^{2} + 2) + 5.

All we have to do is substitute. I'll just do that, I hope you'll get it from the visuals.

<u>First option:</u>

<u />g(x)= ((-2)^{2} + 2) + 5\\g(x) = (4 + 2) +5\\g(x) = 6 +5\\g(x) = 11This works.

<u>Second option:</u>

<u />g(x) = (4^{2} + 2) + 5\\g(x) = (16 + 2) + 5\\g(x) = 18 + 5\\g(x) = 23This does not work

<u>Third option:</u>

<u />g(x) = (0^{2} + 2) + 5\\g(x) = (0 + 2) + 5\\g(x) = 2 + 5\\g(x) = 7This also does not work.

<u>Fourth option:</u>

<u />g(x) = (1^{2} + 2) + 5\\g(x) = (1 + 2) + 5\\g(x) = 3 + 5\\g(x) = 8This works.

<u>Fifth option:</u>

<u />g(x) = (7^{2} + 2) + 5\\g(x) = (49 + 2) + 5\\g(x) = 51 + 5\\g(x) = 56This does not work.
