Given:
The point is (1,-2).
To find:
The function notation of the given point.
Solution:
If a point is (x,y), then its function notation is f(x)=y.
The given point is (1,-2).
Here, x-coordinate is 1 and y-coordinate is -2. So, the function notation of the given point is
[tex]f(x-coordinate)=y-coordinate[/tex]
[tex]f(1)=-2[/tex]
Therefore, the function notation of the given point (1,-2) is f(1) = -2.

Notice that there are similar triangles here:
[tex]\triangle ABD \sim \triangle FED[/tex][tex]\triangle ACD \sim \triangle AEF[/tex]Set up proportions to find the values of x, y, and z.
[tex]\displaystyle \text{Equation I: }\frac{FD}{AD} = \frac{FE}{AB}[/tex][tex]\displaystyle \text{Equation II: } \frac{A F}{AD}=\frac{EF}{CD}[/tex]Let's make this problem simpler by incorporating only 2 variables instead of 3. Let's say that the total distance between the two poles is distance d. Instead of z, let's call it d - y.
Substitute known values or variables into the proportions.
[tex]\displaystyle \text{Equation I: } \frac{d-y}{d} = \frac{x}{6}[/tex][tex]\displaystyle \text{Equation II: }\frac{y}{d}= \frac{x}{12}[/tex]Cross-multiply and simplify Equation I.
[tex]6(d-y)=dx[/tex] [tex]6d-6y=dx[/tex]Cross-multiply and simplify Equation II.
[tex]12y=dx[/tex]We now have two equations that are equal to dx, so we can set them equal to each other.
[tex]6d-6y=12y[/tex]Add 6y to both sides of the equation.
[tex]6d=18y[/tex]Divide both sides of the equation by 6.
[tex]d=3y[/tex]We can substitute this value of d back into either Equation I or II. I am going to substitute d into Equation II.
[tex]\displaystyle \frac{y}{3y} = \frac{x}{12}[/tex]Cross-multiply and simplify the equation.
[tex]12y=3xy[/tex]Divide y from both sides of the equation.
[tex]12=3x[/tex]Divide both sides of the equation by 3.

Explanation:
In a parallelogram, there are only two sizes of angle - two are acute and two are obtuse.
Opposite angles are equal .
Consecutive angles are supplementary because they are co-interior angle on parallel lines.
An additional solution to the one given by Alan P is using the fact that the sum of the interior angles of a parallelogram is 360°.
Let one angle be
x
The size of the other angle is given by
9
x
−
30

x
+

(

x

x

x

°
The obtuse angles are each
180
−
21
=
159
°
The other option where the given angle is the opposite angle is described is well explained by Alan P.
Step-by-step explanation:
The interior angles of the parallelogram are 21° and 159° respectively.
What is parallelogram?
A parallelogram is defined as a quadrilateral in which both pairs of opposite sides are parallel and equal.
In a parallelogram opposite interior angles are equal and the angles on the same side of the traversal are supplementary (i.e) 180°
For the given situation,
The measure of one interior angle be [tex]x[/tex] and
Another angle was given as [tex]9x-30[/tex]°
⇒[tex]x+9x-30[/tex]°[tex]=180[/tex]°
⇒[tex]10x=180[/tex]°[tex]+30[/tex]°
⇒[tex]10x=210[/tex]°
On dividing [tex]10[/tex] on both sides,
⇒[tex]\frac{10x}{10}=\frac{210}{10}[/tex]
⇒[tex]x=21[/tex]°
So, another angle is [tex]9x-30[/tex] = [tex]9[/tex]×[tex]21-30[/tex]
⇒[tex]189-30[/tex]
⇒[tex]159[/tex]°
Hence we can conclude that the interior angles of the parallelogram are 21° and 159°.

EXTRA POINTS---Set up an equation and find the value of x.
Answer:
10)
180-3x =x (corresponding angles are equal)
x=45°
11)180-5x=3x ( same reason)
x=10°
12)180-6x=3x(same reason)
x=20°
Answer: See explanation
Step-by-step explanation:
10) Same side interior angles add up to 180°
3x + x = 180
4x = 180
x = 45
11) Same side interior angles add up to 180°
5x + 3x = 180
8x = 180
x = 22.5
12) 6x is vertical to an angle that has a relationship with 3x (same side interior angles) which means 6x and 3x have to add up to 180° as well
6x + 3x = 180
9x = 180
x = 20

Brooke multiplied 3 and 9 and got 17 Brooke knows her answer is wrong because she know it should be approximately
Answer:
Kindly check explanation
Step-by-step explanation:
If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong
3 * 9 = exactly 27
However, for approximation sake ;
We could round 9 to 10 ; and multiply 10 by 3
10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;
3 * 9 = exactly 27 or approximately 30

Answer:
B. f(x) = -x + 2
Step-by-step explanation:
First, you find the point on the y-axis which is (0,2) in this problem.
This will be your b in y = mx+ b
Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.
This will be your m in y = mx + b
But we don't write the 1 so it will just be -x
Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2
