-6x - 73 = 12x + 143 = …
I need help .
Answer:
x = -12
Step-by-step explanation:
-6x - 73 = 12x + 143
Add 6x to each side
-6x+6x - 73 = 12x+6x + 143
-73 = 18x+143
Subtract 143 from each side
-73-143 = 18x+143-143
-216 = 18x
Divide by 18
-216/18 =18x/18
-12 =x
A plant grows at a constant rate of __ cm per day.
A. write a direct variation equation for the height Y a plant will grow in X days. ___
B. What will be the height of a plant in 9 days? __
C. if the height of the plant is 21 cm, how many days has the plant been growing?
Plant grows at 3CM per day
equation: y= 3x
21 is y so 21= 3x. divide by 3 so it's been 7 days
The following data points represent the number of trick-or-treaters James had each year since he started putting pumpkins in his yard.
54, 56, 53, 54, 56, 55
Using this data, complete the frequency table.
Frequency tables are used to show the number of occurrence of each data in a dataset.
The complete frequency table is as follows:
[tex]\begin{array}{cc}{Trick}&{Years}\\52&0&53&1&54&2&55&1&56&2\end{array}\right][/tex]
The given data are:
54, 56, 53, 54, 56, 55
To complete the frequency table, we simply count each data element and the number of occurrence (i.e. the frequency).
So, we have:
52 has a frequency of 0
53 has a frequency of 1
54 has a frequency of 2
55 has a frequency of 1
56 has a frequency of 2
So, the complete frequency table is:

simplify x^2+xy-yx+y^2 + y^2+yz-zy+z^2 + z^2+zx-xz+x^2
Answer:
2x^2 + 2y^2 + 2z^2
Step-by-step explanation:
x^2+xy-yx+y^2 + y^2+yz-zy+z^2 + z^2+zx-xz+x^2
First step is to put all the same ones together
( FYI, xy and yx is the same thing, just like how
2 x 3 and 3 x 2 is the same thing) this time I'll bracket the groups to make it easier on the eyes
(x^2 +x^2) + (xy - xy) +( y^2 + y^2) + (yz - yz) +
(z^2 +z^2) + (zx - zx)
2x^2 + 2y^2 + 2z^2
All the others just cancel themselves out, for example, xy-xy
When anything minus themselves it will become 0

This is freshman geometry I just started the school year of having absolutely no idea what I’m doing, anything helps!!!
Answer:
x = 12 degrees
y = 50 degrees
Step-by-step explanation:
3x + 144 = 180
3x = 180 -144
3x = 36
x = 12 degrees
Let the angle to the left of 2y-5 be z:
z + 95 = 180
z = 85 degree
z + 2y - 5 = 180
85 + 2y - 5 = 180
2y = 180 - 85 + 5
2y = 100
y = 50 degree

What is the domain and range of this graph?
Answer:
Domain: [-5, 5)
Range: (1, 3]
Brackets and parenthesis are important! Make sure to put them in the correct spot
Step-by-step explanation:
Domain is which x values the line hits. It hits from -5 to 5 but doesn't include 5 as indicated by the open circle.
Range is which y values the line hits. It hits from 1 to 3 but doesn't include 1 because, again, there is an open circle.
When a number is not included, you put it with a parenthesis.
When it is included, you put it with a bracket.
line mp bisects angle kmn,line mq bisects angle lmp, and line mr bisects angle qmp. if the measure of angle rmp is 21, find the measure out angle lmn
Bisection is a process that produces two equal parts of angles or lines. Thus applying the bisection principle, the measure of angle lmn = [tex]168^{o}[/tex]
This question deals with sub-bisection of angles. Bisection is the method required to divide a given angle or line into two equal parts.
From the given question: m<rmp = [tex]21^{o}[/tex] (given)
But,
m<qmp = m<rmp + m<qmr = 2 x m<rmp (addition property of bisected angles)
= 2 x [tex]21^{o}[/tex]
m<qmp = [tex]42^{o}[/tex]
Also,
m<lmp = m<lmq + m<qmp = 2 x m<qmp (addition property of bisected angles)
= 2 x [tex]42^{o}[/tex]
m<lmp = [tex]84^{o}[/tex]
Then,
m<lmn = m<lmp + m<pmn = 2 x m<lmp (addition property of bisected angles)
= 2 x [tex]84^{o}[/tex]
m<lmn = [tex]168^{o}[/tex]
Thus, the measure of angle lmn is [tex]168^{o}[/tex].

Why is the information in the diagram enough to
determine that ALMN ~ APON using a rotation about
point N and a dilation?
O because both triangles appear to be equilateral
O because MNL and ZONP are congruent angles
O because one pair of congruent corresponding angles
is sufficient to determine similar triangles
O because both triangles appear to be isosceles,
ZMLN – ZLMN, and NOP = ZOPN
The reason why the information in the diagram is enough to determine that ΔLMN ≅ ΔPON using a rotation about point N and a dilation is;
C: because one pair of congruent corresponding angles is sufficient to determine similar triangles
Congruent TrianglesFrom the attached diagram, we observe that angles NOP and NML are congruent to each other, thus, we can write that;
∠NOP ≅ ∠NML
Now, since corresponding angles of both triangles LMN and PON are congruent it means we can say that both triangles are indeed similar triangles.
Thus, we can conclude that one pair of congruent corresponding angles
is sufficient to determine similar triangles.

Which of the following are the coordinates of the vertex of y = −x2 + 2x + 1? (2, 1) (1, –2) (1, 2) (–2, 1)
Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:
[tex]\displaystyle y = -x^2 + 2x + 1[/tex]
Recall that the vertex is given by the formulas:
[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]
In this case, a = -1, b = 2, and c = 1.
Determine the x-coordinate of the vertex:
[tex]\displaystyle x = -\frac{(2)}{2(-1)} = 1[/tex]
To determine the y-coordinate, evaluate the function at x = 1:
[tex]\displaystyle \begin{aligned} y(1)&= -(1)^2 + 2(1) + 1 \\ &= 2\end{aligned}[/tex]
In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.
A. 2
B. -2
C. 1/2
D. -1/2
