I can’t but I will ask the question on mine for you because if I find the answer I will tell you it
Answer:
340 phones
Step-by-step explanation:
Make an expression
She repairs 10 phones each day, d.
Each day she repairs 10 phones, it is 10 phones off the total number (450) she has to repair, so we can subtract 10d from 450.
450-10d
We want to find how many she has left after 11 days, so we can substitute 11 in for d
450-10(11)
Multiply
450-110
340
She will still have 340 phones left to repair
The general equation is y-k=a(x-h)² where (h,k) is the vertex.
So in this case we have y+12=a(x+6)².
Plug in x=0, y=-24: -12=36a, and a=-⅓. Therefore y+12=-⅓(x+6)².
