Solve for the equation show all your work |3x-9| = 12
Answer:
x = 7 and x = -1
Step-by-step explanation:
The equation "|3x-9| = 12" can be written into two different equations:
3x-9 = 12 & 3x-9 = -12
This is because the net value inside of the absolute value will always be made positive even if it is negative. Therefore, the net value inside of the absolute value signs can also be equal to the negative of the solution.
Solve 3x-9 = 12:
Add 9 to both sides:
3x-9+9 = 12+9
3x=21
Divide both sides by 3:
3x÷3=21÷3
x=7
Solve 3x-9 = -12
Add 9 to both sides:
3x-9+9=-12+9
3x=-3
Divide both sides by 3:
3x÷3=-3÷3
x=-1
Your answer: x = 7 and x = -1
The temperature Monday morning was -12 degrees.by afternoon,the temperature had risen a few degrees.which of the following could be the temperature?
The temperature Monday morning was -12 degrees and by afternoon, the temperature had risen a few degrees, which means the some temperature has been added, so c. -10 degree Celsius is the right option.
What is temperature?Temperature is a measure of hotness or coldness expressed in terms of any number of arbitrary scales. It shows the direction in which heat energy will spontaneously flow, i.e., from a hotter body (one with a higher temperature) to a colder body (one at a lower temperature).
A burning match is much hotter than an iceberg, but an iceberg has much more total heat energy than a match does. Temperature is not the same as the energy of a thermodynamic system.
Similar to pressure or density, temperature is referred to as an intensive property—one that is independent of the quantity of matter being considered—as opposed to extensive properties, like mass or volume.

The given equation is:
y - 5 = 1/2 (x-4)
On simplifying this,
⇒ y - 5 = (x - 4)/2
⇒ (y - 5) *2 = x - 4
⇒ 2y - 10 = x - 4
⇒ 2y = x - 4 + 10
⇒ 2y = x + 6
Now, let x = 0,
2y = 0 + 6
⇒ 2y = 6
⇒ y = 3
let y = 0,
x + 6 = 0
⇒ x = -6
So, two points of the given equation are (0,3) and (-6,0)
On plotting these points of the graph, we will get the line on the graph.
What is a Line?A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things. The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends. Two points on a line can be used to refer to that line.Because there are so many different geometries in modern mathematics, the definition of the geometry and the idea of a line are tightly related. In analytical geometry, for example, a line in the plane is frequently defined as the collection of points whose coordinates satisfy a given linear equation. However, in a more abstract context, such as incidence geometry, a line may be an independent object, distinct from the collection of points that lie on it.To learn more about Lines, refer to:

Mrs. Nguyen had 25 students in her English class. On her
birthday 1 student gave her chocolates, 12 gave her cards
and 2 gave her flowers.
QUESTION: What percentage of her students brought
something for Mrs. Nguyen on her birthday?
Answer:
60% of her students brought something for Mrs. Nguyen on her birthday.
Step-by-step explanation:
She has 25 students in her class.
12 gave her cards.
2 gave her flowers.
1 gave her chocolates.
Add them together to get 12+2+1=15.
15 students out of 25 can also be written as a fraction:
[tex]\frac{15}{25}[/tex]
This equals 0.6 as a decimal. To find the percentage multiply by 100, to get 60. Therefore 60% of her students got something for her.
Which ordered pair is the best estimate for the solution to the system?
The ordered pair that is the best estimate for the solution to the system is (0.5, -3.5)
Ordered Pair:
An ordered pair refers to a set of two numbers used to locate a point in a coordinate plane. Here the first point refers the x - coordinate and the second value represents the y - coordinate.
Given,
Her we have the equations,
3x - 8y = 29
3x + y = -2
Now, we need to find the solution of the system.
Here we have to use the substitution method in order to solve this one.
For that, we have to rewrite the second equation as,
y = -2 - 3x.
Now, we have to apply the value of y on the equation (1), then we get,
3x - 8(-2 - 3x) = 29
3x + 16 + 24x = 29
27x = 29 - 16
27x = 13
x = 13/27
x = 0.5
When we apply the value of x into the equation, then we get the value of y as,
y = -2 - 3(0.5)
y = -2 - 1.5
y = -3.5
Therefore, the solution of the system is (0.5, - 3.5).

C.9.1 because |-9.1|= -9.1
D.0.91 because |-9.1|=0.91
B. 9.1 because |-9.1| = 9.1
Magnitude of -9.1 is 9.1
Magnitude of a number
A magnitude is the measurement or absolute value of a quantity. A magnitude is represented by a positive real number. Put simply, a magnitude is the size of some quantity. For example, the magnitude of an earthquake, measured on the Richter scale, usually varies between 1 and 10 and represents the size of the earthquake. An earthquake with a magnitude of 8 is much more trouble than an earthquake with a magnitude of 3.
The magnitude of a negative number, say -6? It is (positive) 6. Magnitudes cannot be negative. Consider the idea of a magnitude as a measure of size: there doesn't seem to be a coherent idea of negative size. To make sense of this is to understand that -6 is greater in magnitude than -5 even though -6 is a lower number. For negative numbers the order of magnitude is reversed, just as one counts in the opposite direction on the number line for negative numbers.

C has coordinates (-2,-4)
D is the midpoint of AB.
E is the midpoint of AC.
Prove that DE is parallel to BC.
You must show each stage of your working.
Answer:
The slopes of DE and BC are the same: 0.5. The two lines are therefore parallel.
Step-by-step explanation:
See the attached graph, made in DESMOS.
The midpoints D and E may be determined by taking the average values of x and y that form the endpoints of lines AB (midpoint D) and AC (midpoint E):
Midpoint Endpoint1 Endpoint 2 Midpoint
D A(4,6) B(2,-2) D(3,2) [(4+2)/2 =3 and (6-2)/2 = 2]
E A(4,6) C(-2,-4) E(1,1) [(4-2)/2 =1 and (6-4)/2 = 1]
If DE is parallel to BC, both lines must have the same slope. Find the slopes for DE and BC by calculating the Rise/Run (the change in y over the cahnge in x):
Slope of DE: Rise = (2-1) = 1, Run = (3-1) = 2. Slope = (1/2) or 0.5
Slope of BC: Rise = (-2-(-4)) = 2, Run = (2-(-2)) = 4. Slope = (1/2) or 0.5
The slopes of DE and BC are the same: 0.5. The two lines are therefore parallel.

===================================================
Explanation:
Use the midpoint formula to find that N = (1,6) is the midpoint of J(-3,8) and M(5,4). I'm skipping steps so let me know if you need to see them.
Then draw a circle centered at N with radius NM. The equation of this circle is (x-1)^2+(y-6)^2 = 20
Plug in x = 1 and solve for y to get y = 10.4721 and y = 1.5279
These values are approximate.

Ben Armstrong earns $13.57 an hour plus time and a half for weekend work. Last week he worked his
regular 40 hours plus 8 hours on Saturday. What was his total pay for the week?
Ben Armstrong's total pay for working regular 40 hours plus 8 hours on Saturday is $705.64.
How is the total pay determined?The total pay is the sum of the total pay at the normal pay rate in addition to the total overtime pay at the overtime rate.
The overtime pay rate is usually a time and a half of the normal pay rate.
The normal hourly pay rate = $13.57
The overtime pay rate = 1¹/₂ of $13.57 = $20.355
The total earnings from normal working hours = $542.80 (40 x $13.57).
The total earnings from overtime hours = $162.84 (8 x $20.355).
Ben's total pay for the week = $705.64 ($542.80 + $162.84).
