How do I graph -1, -4?
Sonbull [250]

Answer:

Start at the origin and go to the left by one and go down by 4

Step-by-step explanation:

The x coordinate relates to the horizontal axis and the y axis refers to the vertical axis.

Before we start graphing we must always begin at the origin (0,0)

Since the x value is -1 we have to move left by 1 on the x axis

We would move to the left one value because negative is on the left side

For the y value, we would have to move 4 down on the y axis because this number is also negative.

So your graph should look like this

Hope this helps :)

What is 2c+2=8 ?<br><br> Thanks for your help if you put the answer lol
Juliette [100K]
C= 3 because you subtract 2 on both sides, which is 2c= 6 then you divide 2 on both sides to get c= 3 haha

Which model shows the correct factorization of x2 + 2x – 8?
expeople1 [14]
To factor x^2 + 2x - 8 follow these steps


1) Write to factors, with x as the first term, this way:

(x      )(x      )


2) The sign to the right of the x in the first factor is the same sign of the coeficient of x in the polynomial.

That is +.


The sign to the right of the x of the second factor is the product of the sign of the coefficent of x (this is +) and the sign of the independent term (this is - ).

So that is (+).(-) + -.

Now the two factors have this form:

(x +  ) (x  -  )


3) Now find two numbers whose product is - 8 and whose difference is +2


Those numbers are + 4 and -2.


Then the two factors are:

(x + 4) (x -  2).


So the answer if that the correct factorization is (x + 4) (x - 2)
