Unfortunately, you overlooked the need to share Steps 1-6.

Solve: (log to the base 3 of)(x+2)= (log to the base 3 of) (2x^2-1).

Use (log to the base 3 of)(x+2) as the exponent of 3 in the equation 3 = 3:

(log to the base 3 of)(x+2) (log to the base 3 of) (2x^2-1)
3 = 3

This reduces to x+2 = 2x^2 -1, which, in turn, simplifies to 2x^2 - 1 - x - 2 = 0, or

2x^2 - x - 3 = 0. You could use the quadratic formula or some other method to solve this for x. The roots are 3/2 and -1.

Answer:

When y=7,9 the answer is yes when it = -10,-8 the answer is no.

Step-by-step explanation:

Simple substitution gets us the resulting values. for y=7 we get $15\geq 15$ which is true. For y=9 we get $19\geq 15$ which is also true. For the other values we get a negative number which is not a solution.
