Hello,

y=5+x
y=x²-7
==>x²-7=5+x
==>x²-x-12=0
==>(x-4)(x+3)=0

djyliett [7]

Answer:

(0,6)

(1,5)

(2,4)

(3,3)

(4,2)

Step-by-step explanation:

To solve this table first convert the equation to slope-intercept form (y=mx+b), to do this solve for y in the equation. The slope-intercept form is y=-x+6, where -1 is the slope and 6 is the y-intercept. Then from that, you can get your first point, because you know the y-intercept is 6, therefore when x equals 0 y must be 6. Next, because the slope is -1 that means the y-value decreases by 1 every time the x-value increases by 1. So to find the rest of the y-values simply subtract 1 from the previous y-value.

Let f(x) = 8x^3 − 22x^2 − 4 and g(x) = 4x − 3. Find f(x) over g(x).
Alenkasestr [34]
You would use the long division technique..

Here it looks like:
<span>
            --------------------
4x − 3 |</span> <span>8x^3 − 22x^2 − 4
---------
           |</span>
           |
<span>           |

and like that,,,

after you do this, you will get

2x^2-4x-3-\frac{13}{4x-3}


hope that helps
