Answer: x=15
Step-by-step explanation:
Equation: 107=(9x-115)+(4x+27)
Step 1: 9x+4x-115+27=107
Step 2: 13x-115+27=107
Step 3: 13x-88=107
Step 4: 13x-88+88=107+88
Step 5: 13x=195
Step 6: 13x/13=195/13
x=15
The answer to your question is option d as x is positive ( making it open up), and the vertex is (-3,-4)
This is true. There is no question connected which is why there are no answers!
I think that the answer would be 2 if I am right
