Answer:
We have to use the formule to calculate the vertex which is: V(-b/2a;4ac-b^2/4a)
A) y=x+7 where a=1 b=0 and c=7
By replacing we have: V(0;28/4) V(0;7)
B) y=-x where a=-1 b and c=0 so V(0,0)
Answer:
the answer is 10x^2-30x+20
Step-by-step explanation:
you have to distribute the numbers and multiply then add the matching variables.
