7. x=3 is the midpoint between the roots. The other root is x = 2*3 -(-5) = 11.
8a) f(x) = (x +3)^2 -49. The vertex is (-3, -49). The roots are -10, 4.
8b) y = (x+4)^2 -1. The vertex is (-4, -1). The roots are -5, -3.
8c) f(x) = 2(x +3)^2 -34. The vertex is (-3, -34). The roots are -3±√17.
Well first off if you have a negative sign in front of the seven, DO NOT have a plus sign because it will be confusing. So y-7=13? , You add 7 to 13 and = 20, so y= 20

Answer:that is a triangil
Step-by-step explanation:
Answer:
5.33 unit
Step-by-step explanation:
logically FA = EA - EF = 13.33-8 = 5.33 units
Since, E, F and A all lie on the same line EA . The information ED= units is redundant. Therefore we can say that FA= 5.33 unit
