Answer:
(-4, -7)
Step-by-step explanation:
21y=-147
y=-7
2x-5x(-7)=27
x=-4
Answer:
I think the answer is B.
Step-by-step explanation:
I am very sorry if it is incorrect.
Answer:
y = -(x + 5)² + 4
Step-by-step explanation:
The roots are -3 and -7, so:
y = a (x + 3) (x + 7)
Distribute and complete the square:
y = a (x² + 10x + 21)
y = a (x² + 10x + 25 − 4)
y = a (x² + 10x + 25) − 4a
y = a (x + 5)² − 4a
The vertex is (-5, 4), so a = -1.
y = -(x + 5)² + 4
I hope this helps you
-20-(4x-1)=-15
-20-4x+1=-15
-20+1+15=4x
-4=4x
x=-1
