Which best explains why the equation 7x + 3 = 7x + 3 has infinitely many
solutions?

because no matter what x is, the equation on both sides are the same

Step-by-step explanation: for example we will replace x with 5

7(5) + 3=7(5) + 3

7 times 5 equals 15, plus 3 equals 18, now lets look at the other side, 7 times 5 equals 15, plus 3 equals 18, there fore u could use the number 777,777,777 and you would get the same answer on both sides

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
