Answer:

B. x < -11/3 or x > 7/3

Step-by-step explanation:

absolute value means

3x + 2 > 9 or -(3x + 2) > 9

for 3x + 2 > 9

3x > 9 - 2

3x > 7

x > 7 / 3

for -(3x + 2) > 9

-3x - 2 > 9

-3x > 9 + 2

-3x > 11

3x < -11

x < -11 / 3

<span> 2(2x-3y=3)..................4x-6y=6..........equation 1
3(5x+2y=17) ...........15x+6y=51</span>........equation 2

adding equation 1 and equation 2;
19x=57
x=3

2x-3y=3
(2*3)-3y=3

Simplify -3d^8(-4d^-14). Assume d =/ 0

Alenkinab [10]

Answer:

$\frac{12}{d^6}$

Step-by-step explanation:

$-3d^8\left(-4d^{-14}\right)$

Double negative = Positive:

$3d^8*4d^{-14}$

Apply negative exponent formula:

$3*d^8*4*\frac{1}{d^{14}}$

Multiply:

$\frac{12d^8}{d^{14}}$

Apply exponent rule: $\frac{x^a}{x^b}=\frac{1}{x^{b-a}}$

Thus, $\frac{12}{d^{14-8}}$

Simplify:

$\frac{12}{d^6}$
