Answer:
Step-by-step explanation:
y(y+2)=y²-6
y²+2y=y²-6
2y=-6
y=-3
2[x-(1-3x)]=3(x+1)
2[x-1+3x]=3x+3
2(4x-1)=3x+3
8x-2=3x+3
8x-3x=3+2
5x=5
x=1

Step-by-step explanation:
<u>Finding the unit rate of the graph</u> :
- Take 2 points and find the slope
- ⇒ (0,0) and (12, 25)
- ⇒ m = 25 - 0 / 12 - 0
- ⇒ m = <u>25/12</u>
- The equation is : <u>y = 25/12x</u>
Now, the equations with greater unit rates (in increasing order) are :
Answer: 10n^2 - 10
Step-by-step explanation:
(5n - 5)(2+2n) becomes (5n-5)(2n+2)
= (5n)(2n) + (5n)(2) + (-5)(2n) + (-5)(2)
= 10n^2 - 10
To me it is C. or D. but you would need a second opinion. Sorry.
Point slope form is y-y1= m(x-x1)
So u need another x and y ull hav to guess with what u hav so like it could start as 2-1 or 3-0 but it’s ur choice
