Ranger simplified this expression. 3(2.7x + 5) – 2(4x – 1.6) What was Ranger's simplified expression? 0.1x + 18.2 –16.1x + 11.8
Ymorist [56]

Answer:

Ranger's simplified expression was 0.1x + 18.2

The correct answer is the first option.

Step-by-step explanation:

To simplify the given expression

3(2.7x + 5) – 2(4x – 1.6)

First, we will open the brackets by distributing 3 and 2, that is

(3×2.7x) + (3×5) -(2×4x) -(2×-1.6)

Now, we will get

8.1x + 15 - 8x +3.2

Now, collect like terms,

8.1x - 8x + 15 + 3.2

Then, we will get

0.1x + 18.2.

Hence, Ranger's simplified expression was 0.1x + 18.2.

The correct answer is the first option.

Is the inverse of the function shown below also a function?
ycow [4]

Answer:

Yes

Step-by-step explanation:

Yes.  Here's why:  We can obtain the graph of the inverse of the function shown by reflecting the red graph about the line y = x.  The resulting graph is true for all x values and for all y values; it passes the vertical line test.

Consider the functions f(x) = ( 5 )" and g(x) = (*)* + 6. What are the ranges of the two functions?
nika2105 [10]

Answer:

The range of the function is the set of all possible values that function can take. Both given functions

y=\left(\dfrac{4}{5}\right)^xy=(

5

4

)

x

and y=\left(\dfrac{4}{5}\right)^x+6y=(

5

4

)

x

+6

are exponential functions with base \dfrac{4}{5}.

5

4

.

The graphs of these function you can see in attached diagram.

The range of the function y=\left(\dfrac{4}{5}\right)^xy=(

5

4

)

x

is (0,\infty).(0,∞).

The range of the function y=\left(\dfrac{4}{5}\right)^x+6y=(

5

4

)

x

+6 (this function is translated function y=\left(\dfrac{4}{5}\right)^xy=(

5

4

)

x

6 units up) is (6,\infty).(6,∞).
