You need to add like terms.

Example: 2x + 4y + 8x
Like Terms: 2x,8x
2x + 8x = 10x

New Equation =
10x + 4y

I REALLY NEED HELP, PLEASE HELP !! WORTH 30 POINTS !!
valina [46]

Answer:

2/9

Step-by-step explanation:

y=6(3)^x

Let x =-3

y = 6 * 3^-3

Remember negative exponents move it from the numerator to the denominator

y = 6 *1/3^3

y = 6 * 1/27

y = 6/27

y = 2/9
