Answer:

1) x=0.465

2) option A.

Step-by-step explanation:

1) The given equation is:

{3}^{x + 2}  = 15We rewrite this as logarithm to get:

x + 2 =  log_{3}(15)

The change of base formula is:

log_{b}(y)  =  \frac{ log(y) }{ log(b) }

We apply the change of base formula on the RHS to get:

x + 2 =  \frac{ log(15) }{ log(3) }

x + 2 =  \frac{1.176}{0.477}

x + 2 = 2.465

Group similar terms:

x = 2.465 - 2.000 = 0.465

2)

From the graph, the logarithmic function approaches negative infinity as x approaches -6.

Therefore the vertical asymptote is x=-6

The graph touches the x-axis at x=-5, therefore the x-intercept is x=-5.

The correct answer is A.

What is the solution to the system of equations?
Yuri [45]

Answer:

No solution

Step-by-step explanation:

Note how "2x" shows up in both equations.  This suggests doing a substitution to solve the system.

Focus first on the first equation.  Solving 2x - y = 7 for 2x, we get:

2x = y + 7.

Next, we substitute y + 7 for 2x in the second equation:

y = (y + 7) + 3.

Simplifying this produces:

0 = 10

This is not true and can never be true.  Thus, this system has no solution.
