Solve: |2 + 4x| 11
erastovalidia [21]

Correct option is A) [-13/4, 9/4] .

<u>Step-by-step explanation:</u>

Here we have following equation as  |2 + 4x| = 11 or , |2 + 4x| = 11 . We need to solve for the value of x .Let's find out:

We know that Modulus Function is both positive & negative for particular values of x , i.e.

|2 + 4x| is positive :

⇒ |2+4x|=11

⇒  2+4x=11

⇒  4x=9

⇒  x = \frac{9}{4}

|2 + 4x| is negative :

⇒ |2+4x|=11

⇒  -2-4x=11

⇒  -4x=13

⇒  x = \frac{-13}{4}

Therefore , Correct option is A) [-13/4, 9/4] .

On your own paper graph each system of equations and then describe it: y=x+4 3x+5y=10
ki77a [65]
Each equation form a straight slanting line. For the first equation, it is slanting towards the right which denotes that it has a positive slope. For the the second equation, its plot is slanting towards the left denoting that its slope is negative. Common to both equation is the point (-1.25, 2.75). At this point, the two lines intersect.

What actions did colonists take to protest the Townshend Acts?
brilliants [131]

Answer:

The Townshend Acts would use the revenue raised by the duties to pay the salaries of colonial governors and judges, ensuring the loyalty of America's governmental officials to the British Crown. However, these policies prompted colonists to take action by boycotting British goods.
