Choose the correct simplification of the expression (−2x + 10y)(4x − 6y). (1 point)

ELEN [110]

(-2x+10Y)(4X-6Y) can be simplified as -8x+-60Y because you have to combine like terms such as -2x and 4x.

3x + 4y = 14 x = 2y - 12 Which point satisfies both equations?

Neporo4naja [7]

X = 2y - 12....so sub 2y - 12 in for x in the other equation

3x + 4y = 14
3(2y - 12) + 4y = 14
6y - 36 + 4y = 14
6y + 4y = 14 + 36
10y = 50
y = 50/10
y = 5

x = 2y - 12
x = 2(5) - 12
x = 10 - 12
x = -2

solution is (-2,5) <==

What is the recursive formula for this geometric sequence?–2, –16, –128, –1024, ...

Tatiana [17]

Answer:

$b_n=-2\cdot 8^{n-1}$

Step-by-step explanation:

Denote first four terms of the geometrc sequence as

$b_1=-2,\\ \\b_2=-16,\\ \\b_3=-128,\\ \\b_4=-1024.$

Note that

$b_2=b_1\cdot q\Rightarrow -16=-2\cdot 8;\\ \\b_3=b_2\cdot q\Rightarrow -128=-16\cdot 8;\\ \\b_4=b_3\cdot q\Rightarrow -1024=-128\cdot 8.$

Then the common ratio is

$q=8.$

Therefore, the recursive formula for the geometric sequence is

$b_n=b_1\cdot q^{n-1}\Roghtarrow b_n=-2\cdot 8^{n-1}.$
