{the question is asking to find the value of x not m}
The value of x is 9°
Step-by-step explanation:
8x-2°+47° = 12x+9°{an exterior angle formed by producing the side of triangle is equal to two non adjacent angle}
or, 8x+45° = 12x+9°
or, 8x-12x = 9°-45°
or, -4x = -36°
or, x = -36°/-4
or, x = 9°

What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
According to the given figure, vertices of rectangle ABCD are:
A=(3,0) B=(1,0) C=(1,2) and D=(3,2)
After the transformation of square ABCD we get a rectangle A′B′C′D′.
whose vertices are, A'=(6,0) B'=(2,0), C'=(2,2) and D'=(6,2)
(Here A', B', C' and D' are transformed from points A, B , C and D respectively.
In horizontal stretch by a factor k the point (x,y) in a graph f(x) is transformed to the (kx,y).
And after seeing the coordinates of vertices of square ABCD and rectangle A′B′C′D′
it is clear that there is no change in the y-coordinates in all the vertices of both square ABCD and rectangle A′B′C′D'.
Moreover, the x-coordinates are increasing by multiplying 2. Therefore it is a horizontal stretch by factor 2.
Hence, this transformation is a horizontal stretch by a factor of 2 .

The equation of line q is 5y - 4x = 10. Write an equation of the line that is perpendicular to q and passes through the point (-15, 8)
Answers
Answer:
y = -5/4x - 10.75
Step-by-step explanation:
First, put the equation in slope intercept form by isolating y:
5y - 4x = 10
5y = 4x + 10
y = 4/5x + 2
Perpendicular lines have opposite reciprocal slopes, so the slope will be -5/4
Plug in the slope and the given point into y = mx + b to find b:
y = mx + b
8 = -5/4(-15) + b
8 = 18.75 + b
-10.75 = b
Plug in the slope and y intercept into y = mx + b
y = mx + b
y = -5/4x - 10.75
Answer:
5x + 4y + 43 = 0
Explanation:
y=mx+b
m=slope
b=y intercept
perpendicuar lines have slopes that multiply to get -1
so
solving for y
add 4x both sides and divide by 5 to get
y=4/5x+2
slope is 4/5
perpendicular means the slopes multiply to get -1
so
4/5 times what=-1?
what=-5/4
so
y=(-5/4)x+b
find b
given the point (-15,8)
8=(-5/4)(-15)+b
8=75/4+b
-43/4=b
y=(-5/4)x-43/4
convert to standard form:
5x + 4y + 43 = 0

What is the scale factor (k) of the dilation if C is (-6,9) and C' is (-2,3)?
Answers
Answer:
Step-by-step explanation:
Given the original coordinate as C (-6, 9) and new coordinates after dilation as C' (-2, 3), we can see that the value of the new coordinates has reduces by a factor. Let the factor be k
For the x coordinates:
C' = kC
x' = kx
-2 = k(-6)
-2 = -6k
Divide both sides by -6
k = -2/-6
k = 1/3
For the y-coordinates:
y' = ky
3 = 9k
Divide both sides by 9:
3/9 = 9k/9
1/3 = k
k = 1/3
Hence the scale factor of the dilation is 1/3
Answer:
The scale factor from C' to C is
3
But the scale factor from C to C' (the one you may have asked for in the question) is
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
What we already know is that we have line segments C and C' and we know their lengths.
C = (-6, 9)
C' = (-2, 3)
So the scale factor from C' to C can be easily known if we simply use the rules of division
-6 ÷ -2
and
9 ÷ 3
They both are equal to the outcome, 3.
So we now know that the scale factor from C' to C is 3.
But what about C to C'??
Yes we still have to do division, BUT (you may have guessed it already but), we must switch the positions that the numbers for dividend and divisor were.
-2 ÷ -6 =
0.33333333... or [tex]\frac{1}{3}[/tex]
3 ÷ 9 =
0.33333333... or [tex]\frac{1}{3}[/tex]
So we can decisively conclude that the scale factor of C to C' is [tex]\frac{1}{3}[/tex]

Here are the values of the first 5 terms of 3 sequences: : 30, 40, 50, 60, 70, . . . : 0, 5, 15, 30, 50, . . . : 1, 2, 4, 8, 16, . . . For each sequence, describe a way to produce a new term from the previous term. If the patterns you described continue, which sequence has the second greatest value for the 10th term? Which of these could be geometric sequences? Explain how you know.
Answers
Answer:
1,2,4,8,16.
Step-by-step explanation:
they are a square root of 2 for each question. it will eventually get up higher then additive.
The sequence that has the second greatest value for the 10th term is
1, 2, 4, 8, 16, . . .
The geometric sequences in the given sequences is 1, 2, 4, 8, 16, . . .
What is a sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
Now the given sequences are,
30, 40, 50, 60, 70, . . . :
0, 5, 15, 30, 50, . . . :
1, 2, 4, 8, 16, . . .
For sequence 30, 40, 50, 60, 70, . . . :
we have common difference, d = 10
So, this is an arithmatic sequence.
So, Tn = a1 + (n-1)d
Hence, 10th term of the series,
T10 = 30 + (10-1)10
T10 = 30 + 9*10
T10 = 30 + 90
T10 = 120
For sequence 0, 5, 15, 30, 50, . . .
This is a recurssive sequence
Hence each term of the series is given as,
0
5 = 5*1
15 = 5*(1 + 2)
30 = 5*(1 + 2 + 3)
50 = 5*(1 + 2 + 3 + 4)
.
.
.
.
.
10th term = 5*(1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)
10th term = 225
For sequence 1, 2, 4, 8, 16, . . .
Here common ratio, r = 2
also, Tn = ar^(n-1)
So, T10 = 1*2^(10-1)
or, T10 = 1*2^9
or, T10 = 512
Therefore,
The sequence that has the second greatest value for the 10th term is
1, 2, 4, 8, 16, . . .
and The geometric sequences in the given sequences is
1, 2, 4, 8, 16, . . .
