Answer:
try 3
Step-by-step explanation:
The answer is 4+(9x1/10)+(5x1/1000)
Can i have a brainiest
1/9
Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1
Hope could help :)
Yes!
This would be in-fact a linear equation!
<h3>How?</h3>
This equation is set up in y=mx+b form, therefore we know it is a linear equation.
<h3>Example of a linear equation:</h3>
y=12x+2
The 12 is the mx in the equation.
And the 2 is the B in the equation! :)
That is how we solve that.
Any questions?
Have a great day!
