Answer: 19 minutes

Step-by-step explanation:

Here is the complete question:

takes Andrew 720 seconds to take a shower. He spends an additional 420 seconds eating breakfast.

How many minutes does it take Andrew to take a shower and eat breakfast?

From the question, we are told that Andrew spends 720 seconds to take a shower and also spends an additional 420 seconds eating breakfast. The total time spent by Andrew will be:

= 720 seconds + 420 seconds

= 1140 seconds

We will then convert 1140 seconds to minutes. We should note that 60 seconds = 1 minute. Therefore,

1140 seconds = 1140/60

= 19 minutes

Andrew uses 19 minutes to take a shower and eat breakfast.

Answer:

5/3

Step-by-step explanation:

19x=3+4(x+6)-2

19x=3+4x+24-2

19x-4x=3+24-2

15x=27-2

15x=25

x=25/15

The exponential function, f(x)=2^x, undergoes two transformations to g(x)=3x2^x+5. How does the graph change? Select all that ap
Shalnov [3]

Answer: Options A and C.

Step-by-step explanation:

 The parent exponential function has the form:

f(x)=b^x

This can be transformated as following:

When you multiply the function by a factor <em>a</em> (a*f(x))<em> </em>and <em>a>0 </em>, then the function is  vertically stretched.

When you add a number <em>k</em> to the parent function, the function is shifted up (f(x)+k)

The parent function given in the problem is:

f(x)=2^x

To obtain the function g(x)=3*2^x+5, the parent function is multiplied by a factor 3 (which is greater than 0) and the number 5 is added.

Therefore, the graph is shifted up and vertically stretched.

8-37 better than or equal to 29
Zina [86]

The statement that 8-37 greater than or equal to 29 is false and the correct statement is 8 -  27 is less than 29

<h3>What is an inequality?</h3>

An inequality can be defined as a relation which makes an unequal comparison between two numbers or mathematical expressions.

It is used most often to compare two numbers on the number line by their size

The information given be represented as;

8 - 37\geq 29

Now, let's find the difference from the left side

We have;

- 29\geq 29

From this, we can see that the statement is wrong as - 29 is neither greater than or equal to 29

The correct statement should be; 8 -  27 is less than 29

Thus, the statement that 8-37 greater than or equal to 29 is false and the correct statement is 8 -  27 is less than 29
