Answer:
2) y = x - 4
y = -x + 2
=> x - 4 = -x + 2
=> 2x = -6
=> x = -3
=> y = -3 - 4 = -7
3) y = 3x + 1
y = 5x - 3
=> 3x + 1 = 5x - 3
=> 2x = 4
=> x = 2
=> y = 3(2) + 1 = 7
4) 2x + y = 8 => y = -2x + 8
y = x - 7
=> -2x + 8 = x - 7
=> 3x = 15
=> x = 5
=> y = 5 - 7 = -2
Answer:
Step-by-step explanation:
Since, the variables x and y are inversely proportional.
C and D
5·(2+4) is 30, because u need to add parenthesis first. 2+4 is 6
6·5 is 30.
C is 5·6 and that is 30
D is 5·2 which is 10, then 5·4 which is 20. 10+ 20 is 30.
