20.) Which inequality represents the solution on the graph?*<br><br>

VMariaS [17]

Answer:

Option 2

Step-by-step explanation:

You can see that the graph of the inequality is x <= -3, so you want to find why inequality matches that. Solve each one:

. $3x \geq -9\\x \geq -3$

doesn't match

$-7x\geq 21\\x\leq -3$

Does match, so this is the answer.

Is 5(1/5^3) = 5(5^3)

Lyrx [107]

Answer:

5(1/5^3) ≠ 5(5^3)

Step-by-step explanation:

5(1/5^3) = 5(5^3)

5/27 = 625

5(1/5^3) ≠ 5(5^3)

The sides aren't equal, so this equation is FALSE.

Solve the equation 2x+3/3 - 3x/2=-4<br>Fast please

alina1380 [7]

Answer:

x = 6

Step-by-step explanation:

Assuming the equation is

$\frac{2x+3}{3}$ - $\frac{3x}{2}$ = - 4

Multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions

2(2x + 3) - 9x = - 24

4x + 6 - 9x = - 24

- 5x + 6 = - 24 ( subtract 6 from both sides )

- 5x = - 30 ( divide both sides by - 5 )

x = 6
