Answer:
• (6, -7)
• (-4, 13)
Explanation:
• Option One
2x + y = 5
2(6) + (-7) = 5
12 - 7 = 5
5 = 5 {true}
3y = 15 - 6x
3(-7) = 15 - 6(6)
-21 = 15 - 36
-21 = -21 {true}
• Option Two
2x + y = 5
2(2) + 1 = 5
4 + 1 = 5
5 = 5 {true}
3y = 15 - 6x
3(1) = 15 - 6(2)
3 = 15 - 12
3 = 13 {not true}
• Option Three
2x + y = 5
2(-2) + (-9) = 5
-4 - 9 = 5
-13 = 5 {not true}
3y = 15 - 6x
3(-9) = 15 - 6(-2)
-27 = 15 + 12
-27 = 27 {not true}
• Option Four
2x + y = 5
2(-4) + 13 = 5
-8 + 13 = 5
5 = 5 {true}
3y = 15 - 6x
3(13) = 15 - 6(-4)
39 = 15 + 24
39 = 39 {true}
Answer: There are no real solutions
Answer:
A
Step-by-step explanation:
1.9 about 2, and 4.4 is about 4.
2x4=8
So it is safe to say between 4 and 10.
