Answer:
I gues s it s yes. if correct brainlest answer pla..
It would be y=4x-3 because -11 show that it went down 11 units. So if it is going to go up 8 units, -11+8 is -3.
Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is <em>not</em> 42 - it's 41. So, Sarah is incorrect.
Answer;
p= (1 + sqrt. 181) / 6, (1- sqrt. 181) / 6
Hope this helps!
