Question

Please help me with some questions. **MEDAL**

Answer 1

for the first one all you have to do is plug in the x from the ordered pairs and see if you get the y
so it would be
3 times (2)-1=5 soo it equals the ordered pair (2,5)

Answer 2

Sorry about how many they are, I just have been on this for days...

Answer 3

Answer 4

the third one when it says "is" that means equal so since it says "is 9" then you know is gonna be = to 9 so put it all together and it would be -4x+2=9

Answer 5

number 4 , you add 6 to both sides and get your answer

Answer 6

Answer 7

equal -12 remember when you add -18+6=-12

Answer 8

Answer 9

5. 4x+3=47
-3 -3
4x=44

Answer 10

6. you divide and get 36

Answer 11

for first question
the answer is (2,5)
see here
(x,y)=(2,5)
y=3x-1
y=5,x=2
now put it in the equation
5=3(2)-1
5=6-1
5=5
Hence answer is correct
