2 units horizontally and 2 units vertically

Step-by-step explanation:

x position difference      -2-(-4)=2

y position difference       7-5=2

2 units horizontally and 2 units vertically on a graph

2^2+2^2=8

sq rt 8=2.83 units

What is the area of this figure?
VashaNatasha [74]

Answer:

104cm^2

Step-by-step explanation:

Area of 1st rectangle

given

l=12cm

w=6cm

A =l×w

=12cm×6cm

=72cm^2

Area of 2nd rectangle

given

l=14-6=8cm

w=4cm

A=l×w

=8cm×4cm

=32cm^2

Total area =72cm^2+32cm^2=104cm^2

If the x-value repeats and the y does not, is it a function?
kogti [31]

Answer:

If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.

For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats

a function because no x value is repeating the x value is known as an independent value. Does that make sense?

"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."

Please help me out with this one.
Iteru [2.4K]

Answer:

x = 2

Step-by-step explanation:

because the pint is at the meddle the 2 sides are equal in length therfore:

29 = 9+10x

29 - 9 = 10x

20

\frac{20}{10}  = x

then x = 2

Describe at least two similarities between constructing a perpendicular line through a point on a line and constructing a perpen
Zolol [24]

For a given line, a perpendicular to that one intersects it forming four angles of 90°.

To answer this, to name two similarities, we will see that the construction is exactly the same in both cases, so to say (trivially) two similarities is that:

We will find the slope in the same way

We will find the y-intercept in the same way.

Now let's see how to construct perpendicular lines.

We know that a general line is given by:

y = a*x + b

Where a is the slope and b is the y-intercept.

A perpendicular line to the above one must have a slope equal to the <u>opposite of the inverse of the above slope</u>, thus the perpendicular line will be something like:

y = -(1/a)*x + c

Where we still need to find the value of c.

So the first similarity is that in both cases we will have the same slope (as this does not depend on the fact that this line passes through a point on the line or off the line)

Now, also remember that two perpendicular lines always do intersect, thus the<u> perpendicular line will always pass through a point of the original line</u>.

Now, let's assume that we know that our line passes through the point (x₁, y₁), we will see that it does not matter is this point is on the original line or not.

To find the value of c, we replace the values of the point in the line equation:

y₁ = -(1/a)*x₁ + c

c = y₁ + (1/a)*x₁

Then the line is:

y = -(1/a)*x + y₁ + (1/a)*x₁

Notice that we did not specify if (x₁, y₁) is on the line or not,<u> thus the construction is exactly the same in both cases.</u>

Then to, trivially, say two similarities we could say:

  • We will find the slope in the same way
  • We will find the y-intercept in the same way.
