Answer:

y= -6

Step-by-step explanation:

-4x and 4x are canceled out. -2y+8y= 6y. -12-24=-36

You are left with 6y=-36 . Divide from both sides and -36/6 is -6. So, y=-6.

Hope this helped.

Mila [183]
Ln ( a^(-4) / b^1  c^1 ) =
= ln a ^(-4) - ( ln b + ln c ) =
= - 4 ln a - ln b - ln c =
= - 4 * 2 - 3 - 5 =
= - 8 - 3 - 5 = - 16

zaharov [31]

Answer:

x = 13.4

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

x² + 6.8² = 14.1²

x² = 14.1² - 6.8²

x² = 152.57

Take the square root of both sides

x = 12.3519229272

Rounded

x = 13.4

Which linear inequality represents the graph below?
musickatia [10]

Answer:

A.

Step-by-step explanation:

It has a negative slope, so B and C are eliminated. The graph also has a solid line instead of a dashed line. This means D is eliminated because it is only greater than. If the graph had a dashed line, then D would be correct, but it does not.
