Answer:

To get the slope (which we'll call n) of a line perpendicular to another line with slope (a/b), use

$n = \frac{-b}{a}$

Then we just plug in the point we want to cross and solve for the constant.

Step-by-step explanation:

we see that m = $\frac{1}{2}$

so, $n = -\frac{2}{1} = -2$

now we have the equation

$-2x + b = y$

plugging in (6, -4) we get

$-2(6) + b = -4\\-12+b = 4\\b=4+12=16$

This gives us our function

$y = -2x + 16$

The table and the graph below each show a different relationship between the same two variables, x and y: A table with two colum

Bezzdna [24]

So to answer this we have to look at the graph, on the right.

Just imagine that your stretching the graph to the right so that it shows the number 12. Now we can plot our point, right? Nope.

The graph isn't high enough. You have to stretch it up more, so that it shows....
What number will it show?

Since the y points are incrementing by 60, it will be
300+60 = 360

So we have to stretch the graph up to make it say 360.

Now we can plot our point at (12, 360)

Now, since it's asking how much more would it be on the graph than the table, we have to look at the table, and find how much y would equal if x=12.

So first let's find how much x is multiplied by to get y.

We can find this by dividing y/x

100/4=25

So x·25 = y

Since x=12...

12·25=300

So y one the table equals 300
And y one the graph equals 360

Subtract to find the answer

360-300 = 60

The answer is 60

Hope the helps! :)

What is the domain. How do I find it?

Morgarella [4.7K]

Answer:

All real numbers

Step-by-step explanation:

Here, we want to get the domain

The domain refers to the possible x values of the function

As we can see, the plot extends thoroughout the entirety of the graph

This extends from positive infinity to negative infinity

This means that the domain is all real

If the basic measuring unit in base-7 is 49 circles, what does the measuring unit of size .001seven look like

Serjik [45]

The measuring unit is the standard unit of a quantity

The measuring unit of size 0.001 is represented by one millionth circle

<h3>How to determine the unit of base 0.001</h3>

The basic measuring unit in base 7 is given as:

49 circles

The above can be represented as:

Base 7 = 49 circles

Represent the base with n.

So, we have the following rule

$Circle = n^2$

For measuring unit 0.001, we have:

$Circle = 0.001^2$

Evaluate the square

$Circle = 0.000001$

This means that,

The measuring unit of size 0.001 is represented by one millionth circle
