The Allied Taxi Company charges $2.50 to pick up a passenger and then adds $1.95 per mile. Isaac was charged $27.46 to go from o

ne city to another. If x represents the number of miles driven by the taxi, which linear equation can be used to solve this problem, and how many miles did Isaac travel, rounded to the nearest tenth?
A.)1.95x + 2.50 = 27.46; Isaac traveled 15.4 miles.
B.)1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.
C.)2.50x + 1.95 = 27.46; Isaac traveled 11.8 miles.
D.)2.50x + 1.95 = 27.46; Isaac traveled 10.2 miles.

The ratio of the area between a small square of land and a large squareof land is 3: 7. Given that the total area of the two squ
lakkis [162]

Given:

The ratio of the area between a small square of land and a large square

of land is 3: 7.

Total area of the two squares of land (in sq. meter) is 4000.

Required:

The area of each square of land.

Answer:

We have the ratio of the area between a small square of land and a large square of land is 3: 7.

Let

x^

be the area of the square of land.

Then their ratio is given by,

3x^:7x^

Also given that the total area of the two squares of land (in sq.meter) is

4,000.

The area of

Therefore,

\begin{gathered} 3x^+7x^=4000 \\ \Rightarrow10x^=4000 \\ \Rightarrow x^=400 \\  \end{gathered}

Therefore,the area of small square (in sq. meter) is,

3x=3(400)=1200

and the area of large square (in sq. meter) is,

7x=7(400)=2800

Final Answer:

The area of small and large square respectively (in sq. meter) is,1200 and 2800.

How is the graph of y=9(3)^x-2 -6 translated from the graph of y=9(3)^x ?
USPshnik [31]
For this case we have the following function:
 y = 9 (3) ^ x
 Applying the following transformations we have:
 Horizontal translations
 Suppose that h> 0
 To graph y = f (x-h), move the graph of h units to the right.
 y = 9 (3) ^ (x-2)
 Vertical translations
 Suppose that k> 0
 To graph y = f (x) -k, move the graph of k units down.
 y = 9 (3) ^ (x-2) - 6
 Answer:
 
2 units to the right
 
6 units down
