Answer:
y=2/15x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-5-(-3))/(-15-0)
m=(-5+3)/-15
m=-2/-15
m=2/15
y-y1=m(x-x1)
y-(-3)=2/15(x-0)
y+3=2/15(x)
y+3=2/15x
y=2/15x-3
Answer:

Step-by-step explanation:
Let's find our C value for the quadratic equation.

That is our C. Since we added 9 to one side, we have to do the same to the other. We get:

Now, lets form the left side as a binomial squared.

Let's square both sides now:

Now, we subtract 3 from both sides to isolate the variable, X:

This means that the answers are:

I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer
9×9=81 so it would be 9cm
Answer:
