Write an equation that represents a vertical translation 7 units down of the graph of g(x)=|x|

Answers

Translation involves changing the position of a function.

The equation that represents the new function is: [tex]\mathbf{g'(x) = |x| - 7}[/tex]

The parent function is given as:

[tex]\mathbf{g(x) = |x|}[/tex]

The rule of translating a function down is:

[tex]\mathbf{(x,y) \to (x,y-h)}[/tex]

Where: h is  the number of units translated down

i.e. h = 7

So, we have:

[tex]\mathbf{g'(x) = g(x) - h}[/tex]

Substitute [tex]\mathbf{g(x) = |x|}[/tex]

[tex]\mathbf{g'(x) = |x| - h}[/tex]

Substitute 7 for h

[tex]\mathbf{g'(x) = |x| - 7}[/tex]

Hence, the required function is: [tex]\mathbf{g'(x) = |x| - 7}[/tex]

The equation that represents the given situation is g(x) = |x|-7

To write an equation that represents a vertical translation 7 units down of the graph of g(x) = |x|, we need to modify the original function accordingly.

A vertical translation can be represented by adding or subtracting a constant to the function. In this case, since we are translating the graph downward by 7 units, we subtract 7 from the original function:

g(x) = |x| - 7

Thus, the equation that represents this vertical translation is g(x) = |x| - 7.

This results in each point on the graph of g(x) = |x| shifting 7 units downward, creating the new graph of g(x) = |x| - 7.

Answers

1 out of 6 time you would be able to get three the third time 

If a six sided die is tossed two times and '3' shows up both times, the probability of a '3' on the third trial is  [tex]\frac{1}{6}[/tex]

Given :

A six sided die is tossed two times and '3' shows up both times

'3' shows up both the times .

When the dice is rolled third time. there are 6 possibilities comes up

In the third trial , we have six possibilities 1,2,3,4,5,6

Out of six possibilities , the chance of getting '3' is only once

So, the probability of a '3' on the third trial is [tex]\frac{1}{6}[/tex]

Is it possible for two linear functions whose graph are parallel to have the same y-intercept

Answers

If you have e two linear functions and on a graph they are parallel that means they have the same slope with different y intercepts. If they are parallel and have the same y intercept then they would be the same graph. So no it’s not possible because there would not be two different graphs/functions; they would be exactly the same.

how can i turn 7/2 into a decimal

Answers

We can split it into two numbers : 6 and 1

half of 6 is 3 as you need 2 lots of 3 to make six
half of 1 is 0.5 as you need 2 lots of 0.5 to make 1

therefore 3 + 0.5 is 3.5.

you need 2 lots of 3.5 to make 7
One method would be to get the denominator into a more common form for dealing with decimal values. Notice the root dec- , the Latin root for "10" in the word decimal. This describes the fact that our common number system, the decimal system, is based on powers of 10. To prepare 7/2 for conversion to decimal, we should first make sure its denominator is some power of 10. To make the conversion, let's multiply it by 1 in the form of 5/5:

[tex] \frac{7}{2} \cdot \frac{5}{5} = \frac{35}{10} [/tex]

Or, as a mixed number:

[tex]3 \frac{5}{10} [/tex]

If you're familiar with how to read decimal values, "3 and 5 tenths" can be written in decimal form as 3.5.

Answers

The answer to this question should be: 
1. definition of supplementary angles
2. 115
3. definition of acute angle

Supplementary angles mean that the angle will add up to 180°. In this case, that means PQR + RQS= 180° where PQR=115°
So the RQS would be 180-115=65° Acute angle is when the angle is <90° so RQS is acute angles
