Which is a correct first step in solving the inequality –4(2x – 1) > 5 – 3x?

distribute –4 to get –8x + 4 > 5 – 3x.
distribute –4 to get –8x – 1 > 5 – 3x.
subtract 2x from both sides of the inequality.
add 1 to both sides of the inequality.

The correct option is A. Distribute –4 to get –8x + 4 > 5 – 3x

Step-by-step explanation:

The inequality is given to be : –4(2x – 1) > 5 – 3x

To solve this given inequality :

STEP 1 : Distribute -4 over 2x - 1

⇒ -8x + 4 > 5 - 3x

STEP 2 : Add -4 on both the sides

⇒ -8x > 1 - 3x

STEP 3 : Add 3x on both the sides

⇒ -5x > 1

Therefore, The correct first step to solve this inequality is : Distribute –4 to get –8x + 4 > 5 – 3x

Hence, The correct option is A. Distribute –4 to get –8x + 4 > 5 – 3x

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
