Algebraic expresion: 56-2x

2x-56. This is the answer because since you don't know what the number is it is gonna be x and twice a number would be 2x. The 56 is subtracted from the 2x because decreased means subtraction.

If f(x)= 2x+5 and g(x)= 3x2 +2x+5, what is f(3)+g(2)?
Karo-lina-s [1.5K]

Answer:

32

Step-by-step explanation:

1. find f(3) = 2x + 5

a) y = 2(3) + 5

b) y = 6 + 5

c) y = 11

2. find g(2) = 3x² + 2x + 5

a) y = 3(2)² + 2(2) + 5

b) y = 3(4) + 4 + 5

c) y = 12 + 4 + 5

d) y = 21

3. add f(3) + g(2)

a) 11 + 21

b) = 32

SpyIntel [72]

Answer:

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Step-by-step explanation:

Given

f(d) = (0.5 * 10^{-4})^d

g(H+) = -log_{10}(H+)

Required

Find the composite function g(f(d))

We have:

g(H+) = -log_{10}(H+)

Substitute f(d) for H+

g(f(d)) = -log_{10}(f(d))

Substitute f(d) = (0.5 * 10^{-4})^d

g(f(d)) = -log_{10}((0.5 * 10^{-4})^d)

Apply law of logarithm

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Hence, the function is:

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})
