Question

IDK THIS ONE PLZ HELP THANK YOU

Answer 1

Answer:

No, no, yes, yes

Step-by-step explanation: All you have to do is plug in the x and y values.

9(4) + 2(-5) = 13

36 + -10 = 13

26 = 13

The first one is no.

9(0) + 2(-8) = 13

0 + -16 = 13

-16 = 13

The second one is no.

9(1) + 2(2) = 13

9 + 4 = 13

13 = 13

The third one is yes.

9(3) + 2(-7) = 13

27 + (-14) = 13

13 = 13

The fourth one is yes.

Answer 2

For this problem you can plug in the given values of x and y to the equation and see if its correct.

For the first one: 9(4)+2(-5)=13

36-10=26. 26 is not equal to 13 so your answer would be no.

For the second one: 9(0)+2(-8)=13

0-16=-16. -16 is not equal to 13 so your answer would be no.

For the third one: 9(1)+2(2)=13

9+4=13. 13 is equal to 13 (same number) so this would be yes.

For the fourth one: 9(3)+2(-7)=13

27-14=13. 13 is equal to 13 so this would be yes.
