Answer:

7y=14. 2x - 4y = 18. (-3x + 2y = 1 ) 3. 2x+6y=18. -qx+6y=3. -7x=21 y=2. 3x + 5y =-5. 3x +0=-5. X=-3. 3x+2y = 1. 10. -10. -3x + 2y. 9+27='s. 끓들 x=-5. (-5,2) y=-4. 3.

Step-by-step explanation:

x=2(y+3). 3 x - 6 y = 18. 3x−6y=18. Add 6y to both sides. Add 6y to both sides. 3x=18+6y. 3x=18+6y

Determine whether the graph represents a proportional relationship.
olya-2409 [2.1K]

No, it is not a proportional relationship because the graph does not go through the origin. A proportional relationship is supposed to be a straight line, starting from the origin. It starts on the number 4.

8.

2 terms on left side, 3 on right side

9.

All variables count as coefficients,  so they’d be 8m, k, and -16k

10.

The constants are just numbers on their own, or without a variable next to it. Here it’d be 10 and -4
