x = 8

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

72 + 9x + -4x = 112 + 4x + -4x

Combine like terms: 9x + -4x = 5x

72 + 5x = 112 + 4x + -4x

Combine like terms: 4x + -4x = 0

72 + 5x = 112 + 0

72 + 5x = 112

Add '-72' to each side of the equation.

72 + -72 + 5x = 112 + -72

Combine like terms: 72 + -72 = 0

0 + 5x = 112 + -72

5x = 112 + -72

Combine like terms: 112 + -72 = 40

5x = 40

Divide each side by '5'.

x = 8

Find all possible values of b such that 4x² + bx + 3 can be factored. Check all that apply.
aleksklad [387]

The possible values of b are 7 and 8

<h3>How to determine the possible values of x?</h3>

The expression is given as:

4x² + bx + 3

Next, we test the options to determine the values of b

<u>Option 1: b = 13</u>

So, we have:

4x² + 13x + 3 ---- this cannot be factorized

<u>Option 2: b = 7</u>

So, we have:

4x² + 7x + 3  

Expand

4x² + 4x + 3x + 3

Factorize

4x(x +1) + 3(x + 1)

Factor out x + 1

(4x + 3)(x + 1) ------ this can be factorized

<u>Option 3: b = 8</u>

So, we have:

4x² + 8x + 3

Expand

4x² + 6x + 2x + 3

Factorize

2x(2x +3) + 1(2x + 3)

Factor out 2x + 3

(2x + 3)(2x + 1) ------ this can be factorized

<u>Option 4: b = 1</u>

So, we have:

4x² + x + 3 ---- this cannot be factorized

Hence, the possible values of b are 7 and 8

What is the slope of <br> (7,-30) and (11,-54)
timama [110]

Answer:

-6

Step-by-step explanation:

we just need to do the step slope=(y2-y1)/(x2-x1)

so slope =-30-(-54)/(7-11)=24/-4=-6
