Answer:
Step-by-step explanation:
We don't have any statements from which to choose, but I did ind a couple of things that might be useful to you. Solving the system simultaneously for a, b, and c gives back a quadratic that is and it has a vertex of (5, -.8). It opens upwards and is very wide open, which means that its vertex is a minimum. It has real zeros of x = 7 and x = 3, and a y-intercept of (0, 4.2). Not sure what else there is to tell you so hopefully I covered something of importance!

Answer: B
Step-by-step explanation:
Answer:
a +b -3c +15
Step-by-step explanation:
Write the subtraction you want to perform, use the distributive property, collect terms:
(3a-4b-c+6) -(2a-5b+2c-9)
= 3a -4b -c +6 -2a +5b -2c +9 . . . . . . distribute the minus sign
= a(3-2) +b(-4+5) +c(-1-2) +(6+9) . . . . find and group like terms
= a +b -3c +15
