Step-by-step explanation:
Answer:
x = 3
y = -5
Step-by-step explanation:
It would be very easy to eliminate y by adding the two equations,
4x - 7y = 47
<u>6x + 7y = -17</u>
10x = 30
x = 3 4(3) - 7y = 47
12 - 7y = 47
-7y = 35
y = -5
Check: See if the values work in the second equation
6(3) + 7(-5)
= 18 - 35
= -17 It looks like they work, so we know we have the correct values
#2. (-10, 0) (-10, -8) (0, -8)
#3. (-10, 0) (-10, 8) (-7, 8)
#4. (-10, 0) (-7, 0) (-7, 8)
#8. (0, 8) (0, 0) (8, 0) (10, 4)
#9. (-7, 0) (-7, 8) (0, 8) (0, 0)
#10. (-10, 0) (0, 0) (0, -8)
Not sure about the others. Hope this helps, though.
