The correct answer is: [A]: " 2" .
_______________________________________________________
Explanation:
_______________________________________________________

5x - 4 = 3x ;

Subtract "3x" from each side of the equation;

5x - 4 - 3x = 3x - 3x ;

2x - 4 = 0 ;

Add "4" to each side of the equation;

2x - 4 + 4 = 0 + 4 ;

2x = 4 ;

Divide each side of the equation by "2" :

2x / 2 = 4 / 2 ;

x = 2 ; which is: "Answer choice: [A]: " 2" .

Explain how you can use the distributive property to check the binomial factors when a trinomial has been factored. Include an e

erica [24]

What you can do is split one of the binomials and then apply the distributive property if f(x) = (x + 3)(x -2) split the 1st binomial f(x) = x(x -2) + 3(x -2) now apply the distributive property to get
f(x)=x2−2x+3x−6
which simplifies to
f(x)=x2+x−6

2. The number of atoms of a particular chemical element is modelled by

____ [38]

9514 1404 393

Answer:

a) 600

b) see below

c) 1.26 hours

Step-by-step explanation:

a) The value of y when x=0 is the coefficient of the exponential term:

y = 600·3^(-0) = 600·1 = 600

There were 600 atoms to start.

b) see attached for a graph

c) The graph shows 150 atoms at t = 1.26, about 1.26 hours after the start of time counting.

If you want to find that value algebraically, substitute for y and solve for x. Logarithms are involved.

150 = 600·3^(-x)

150/600 = 3^(-x)

log(1/4) = -x·log(3)

x = -log(1/4)/log(3) = log(4)/log(3) ≈ 1.2618595

After about 1.26 hours, there were 150 atoms.
