Answer:

x=2

Step-by-step explanation:

27^x could also be written as 3^3x because 27 is 3^3. From here you know 3^x+4 is 3^3x. x+4 is 3x.With basic algebra you can find that x is 2

Answer:

x= 2

Step-by-step explanation:

consider

27 = 3³

__________________________

${3}^{x + 4} = {27}^{x}$

${x}^{x + 4} = ( {3}^{3} )^{x}$

${3}^{x + 4} = {3}^{3(x)}$

${3}^{x + 4} = {3}^{3x}$

$x + 4 = 3x$

$4 = 3x - x$

$4 = 2x$

$\frac{4}{2} = x$

$2 = x$

Consider the two functions described below. Function 1 describes the cost, y, to park in a parking lot for x hours. There is a f

Len [333]

Statement B explains correctly that the parking garage charges a higher rate per hour than the parking lot. Statements B and D are the same.

Step-by-step explanation:

Step 1:

For the parking lot, there is a flat fee of $7.00 and then a charge of $1.00 every hour.

So if a vehicle was parked for 1 hour charges are 7 + 1 (1) = $8,

If parked for two hours charges are 7 + 1 (2) = $9.

Step 2;

To understand the pricing of the parking garage, we must plot the points of the graph.

The points on the graph are (0, 4), (1, 6), (2, 8), (3, 10), (4, 12), (5, 14)...

So for the parking garage, there is a flat fee of $4 and then a charge of $2.00 every hour.

So if a vehicle was parked for 1 hour charges are 4 + 2 (1) = $6,

If parked for two hours charges are 4 + 2 (2) = $8.

Step 3:

Comparing both the parking lot and the parking garage, we get that the flat fee for the parking lot is higher while the parking charges for an hour are higher for the parking garage which is statement B.

Statement B and D are the same.

$f'(x)\ge0$ for all $x$ in [-3, 0], so $f(x)$ is non-decreasing over this interval, and in particular we know right away that its minimum value must occur at $x=-3$ .
