Answer:
Group the like terms
6x + 3x - x + 9
Work out the x values together and then add the 9
9x - x + 9
8x + 9
your final answer should be about 8x + 9 as it cannot be simplified anymore
Answer:
A) $15
Step-by-step explanation:
let x represent the regular price of the mirror
so, 20% of x = 3
20/100 * x = 3
20x = 300
x = 300/20
x = 15
Hence, the regular price of the mirror is $15
The scale factor is 5/3
9(5/3) = 15
The y intercept is 2.25 and x intercept is -3
