Trust me:  You must know how to do this basic factoring yourself.

x^2 -5x - 6 factors into (x-6)(x+1).  Note how I got that:  -6 is the product of 1 and -6, and -6 + 1 = -5.

You could also factor this by grouping:

x^2 -5x - 6 = x(x-6) + 1(x-6).  Note how the middle terms combine to produce -5x and how (x-6) is a factor common to both terms; this leaves (x+1).  So the factors are (x-6)(x+1).

What is the value of x in the equation 8x – 2y = 48, when y = 4?
Phoenix [80]
Hey there!

So, if y=(4), this would mean that we would do (2 \ * \ 4) and from this, we would get 8. 

We will then need to find what is (x).

(x) = 7

8*7 = \boxed{56}

So, the equation would really look like . . .

\left[\begin{array}{ccc} 8*(7)-2*4 = 48 \\ \\ x=\boxed{7}\end{array}\right]

Hope this helps.

Select the correct answer.
wariber [46]

Answer:

<u>~Senpi boi here~</u>

Step-by-step explanation:

Multiply all terms by x and cancel:

x+2x+1=1x

3x+1=x(Simplify both sides of the equation)

3x+1−x=x−x(Subtract x from both sides)

2x+1=0

2x+1−1=0−1(Subtract 1 from both sides)

2x=−1

2x

2

=

−1

2

(Divide both sides by 2)

x=

−1

2

Check answers. (Plug them in to make sure they work.)

x=

−1

2

(Works in original equation)

<u>Answer:</u>

<u>x= −1/2</u>
