Answer:

Step-by-step explanation:

6x + 9 = 57

6x = 57 - 9

6x = 48

x = 48/6

x = 8

no...I dont agree with Amanda.

I arrived at x = 8.....and this can be confirmed by subbing in 8 for x back into the original equation.

6x + 9 = 57......x = 8

6(8) + 9 = 57

48 + 9 = 57

57 = 57 (correct)

You basically look at the bar graph on the right and see which statement is true. Brainliest and thank you!

Answer:

D

Step-by-step explanation:

To check this answer, you could obviously graph the points, but without graphing, you can tell the line would be straight because each x value is multiplied by the same number to get the corresponding y value.

3 x 5 = 15, 4 x 5 = 20, etc. This shows linear growth. If each x value were multiplied by twice itself (3 x 6, 4 x 8, and so on), you wouldn't have a straight line because the number that x is multiplied by changes depending on the value of x.
