Answer:
5/21
Step-by-step explanation:
Take -3/7 and -2/3 subtract them. (-3/7) - (-2/3) find a common denominator and alter fractions based on it. -9/21 + (14/21)
The answer is B.red
the reason:
if x=2
-2 (2)+ 5y = 10
-4 +5y = 10
5y = 10+4
5y = 14
y = 2.8
now we have the point (2 . 2.8) which is absolutely on the line -2x + 5y = 10
when we look for it we see that it's on the line b which means line b is -2x + 5y = 10
5*7x/7-1x
35x/7-1x
5x-1x
4x
(you can also do 7x/7 first)
Hope this helps
