Yes she would be right as for how i got the answer first i started by using 15 hours as 100% then i times fifteen by 20% which gave me three hours then add three hours to fifteen and it gave me 18. so she worked 120% more than last week hoped that helped
I’m pretty sure c is the right answer
The answer is c hope this helps
Answer:
Top right option: g(x) = (x+1)(x-3)
Step-by-step explanation:
x=-1 is the solution to x+1=0
x=3 is the solution to x-3=0
Therefore, your expression so far is (x+1)(x-3) or x²-2x-3.
Since the vertex must be (1,-4) we must check if x=1 satisfies the equation x=-b/2a:
x=-b/2a
1=-(-2)/2(1)
1=2/2
1=1
Both sides are equal to each other, so the final function is g(x) = (x+1)(x-3)
