Well x^2+10x-3 is a quadratic so we are looking for its lowest point (minimum). If you graph it the answer is (-5, -28) so A. You can do it algebraicallly (x+5)=0. X=-5 and look at -28 for y. Either way you get A as the local minimum/ lowest point of graph.
Answer:
y = -8/9
Step-by-step explanation:
Answer:
x=-21
Step-by-step explanation:
x-7=2x+14
-7=x+14
-21=x
Answer:

Answer:
16.67%
Step-by-step explanation:
