Solve for x: 9^(x-8) = 3^(4x-12)

Mathematics
1 answer:
MissTica4 years ago
5 0

Answer:

x = -2.

Step-by-step explanation:

9^(x - 8) = 3^(4x - 12)

9 = 3^2 so we can write:-

3^2(x - 8) = 3^(4x - 12)

Since the base 3,  is the same:-

2(x - 8) = 4x - 12

2x - 16 = 4x - 12

2x - 4x = -12 + 16

-2x = 4

x = -2

2 Points<br> if f(x) = x2 + 3x + 5, what is f(3 + h)?
r-ruslan [8.4K]

Answer:

h² + 9h + 23

Step-by-step explanation:

Given

f(x) = x² + 3x + 5

To evaluate f(3 + h) substitute x = 3 + h into f(x), that is

f(3 + h) = (3 + h)² + 3(3 + h) + 5 ← expand (3 + h)² using FOIL

            = 9 + 6h + h² + 9 + 3h + 5 ← collect like terms

            = h² + 9h + 23
