Answer:
C) 40
Step-by-step explanation:
On the plot it shows (2,80) so you divide 80 by 2 to get 40
-7, -1, 1, and 7 are all whole number factors
I need the options to the questions
<span>x^2-6x+-14=0 works out the same way</span>
2.5y + 3x=7 (1st)
5x - 2.5y = 5 re-write -2.5y + 5x = 5 (2nd)
2.5y + 3x=7 (1st)
-2.5y + 5x = 5 (2nd)
---------------------------add
8x = 12
x = 12/8 = 1.5
2.5y + 3x=7
2.5y + 3(1.5)=7
2.5y = 7 - 4.5
2.5y = 2.5
y = 1
answer
solution (1.5 , 1)
