Hello,
++++++++++++++++++
Answer B
++++++++++++++++++
2x²+28x-5=2(x²+2*7x+49)-5-2*49=2(x+7)²-103
+++++++++++++++++
Yes. 450 ÷ 9 = 50, 450 ÷ 5 = 90, 450 ÷ 10 = 45
The answer would be the top right graph where none of the lines intersect since it shows that there is no possible real solutions for the system if none of the lines intersect on a certain point.
Remember: If the lines intersect, there is a solution; if the lines do not intersect, there is no solution; if the lines fall on the same line, or the equations are equivalent, then the solution is all real numbers.
The answer to this question is C.2 I think
Answer:
I know #1 but not #2 it's
(10x2)+4=24 it's still less then 25 :)
