Answer:
m = -4
Step-by-step explanation:
You want the solution to the "two step" equation m -4 = 2m.
Two-step equationA "two-step" linear equation is one that can be solved in two steps. The steps in general are ...
addition of somethingmultiplication by somethingThe "inverse" properties of addition and multiplication are used to identify the quantities added or multiplied.
Forms of a two-step equationThere are two forms a two-step equation might take:
ax +b = c
ax +b = cx
You will notice that one side of the equal sign has a sum of two terms: a term with the variable, and a constant term without the variable. The other side of the equation will have one term, which may be either a constant term or a variable term.
First stepThe idea of the first step is to make sure the variable term ends up on one side of the equal sign, and the constant term ends up on the other side.
The parts of the first step are ...
identify the kind of term on the side of the equation with one termidentify the term of the same kind on the other side of the equal signadd the opposite of that identified term to both sides of the equation.For the given equation ...
m - 4 = 2m
The term by itself is a variable term. The variable term on the other side of the equation is "m". The first step will be to add "-m" to both sides of the equation.
m -4 -m = 2m -m . . . . . . -m added to both sides
-4 = m . . . . . . . . . . . . . simplify
Now, we have a variable term (m) on one side of the equal sign, and a constant term (-4) on the other side. This is the desired result of the first step.
Second stepThe idea of the second step is to make the coefficient of the variable be 1. We do that by multiplying both sides of the equation by the reciprocal (inverse) of the coefficient of the variable.
For the equation ...
ax = b
we multiply by the reciprocal of 'a', which is 1/a.
(ax)(1/a) = b(1/a)
x = b/a . . . . . . . . . . . effectively, we're dividing by 'a'
In the given equation, we have ...
-4 = m
which already has a coefficient of 1 on the variable m. This means we're done, and no additional step is actually needed.
The solution is m = -4.
__
Additional comment
There is another form of 2-step equation you may see occasionally:
a(x +b) = c
Solving this can be done by reversing the order of the steps: first divide by the coefficient of x, then subtract the constant.
x +b = c/a
x = (c/a) -b
If the variable term inside parentheses has a coefficient other than 1, it may be useful to eliminate parentheses using the distributive property, then solve like a regular 2-step equation.
how many fix points are there for the function f (x) =x^3
The fix points of the function f (x) = x³ are,
⇒ x = 0, x = 1 and x = -1
What is fixed point of a function?
The fixed point of a function is determine by solving the function
f (x) = x.
The function is given as;
⇒ f (x) = x³
Since, The fix point of a function is determine by solving the function
f (x) = x
Hence, we can solve as;
f (x) = x
x³ = x
x³ - x = 0
x ( x² - 1 ) = 0
x ( x² - 1² ) = 0
x ( x - 1 ) ( x + 1 ) = 0
Equate each term to zero,
x = 0
x - 1 = 0 ⇒ x = 1
x + 1 = 0 ⇒ x = -1
Therefore, The fix points of the function f (x) = x³ are,
⇒ x = 0, x = 1 and x = -1

As per the question, The day after a hurricane, the barometric pressure in a coastal town has risen to 29.7 inches of mercury, which is 2.9 inches of mercury higher than the pressure that occurred when the eye of the hurricane passed over.
We are supposed to form an equation representing the situation and calculate the barometric pressure when the eye passed over.
Let's assume that [tex]x[/tex] represents the pressure of barometric pressure when the eye of the hurricane passed over.
So using the concept of linear equation, we can form an equation as,
[tex]2.9+x = 29.7[/tex]
And pressure of barometric pressure when the eye of the hurricane passed over and pressure is
[tex]x=29.7-2.9\\x=26.8[/tex]
So 26.8 inches of mercury is the barometric pressure when the eye of the hurricane passed over.

. Verify the concepts you havelearned about the Law of Acceleration in doing some problem – solving exercises.1.The rising concern among athletic trainers regarding concussions among football playershas prompted numerous studies of the effectiveness of protective head gears.
1.One study suggests that concussions may result from impacts rated at 740 m/s2. If a player’s head mass (with helmet) is 6 kg and considered to be a free body, then what net force would be required to produce an acceleration of 740 m/s2?2.Captain John Stapp of the U.S. Air Force tested the human limits of acceleration by riding on a rocket sled of his own design.
2.His rocket sled, known as the Gee Whiz, had a mass of about 82 kg. What net force would be required to accelerate Gee Whiz and 82 kg Stapp at 450 m/s2 (the highest acceleration tested by Stapp)?3.Space Shuttle Max is one of the extreme rides in Enchanted Kingdom.

Answer: 1. f = 444N
2. f = 36900N
3. a=34 m/s2
Step-by-step explanation:
f=net force. a=acceleration. m=mass.
f = m*a
1. f = m*a
f = 6 * 740
f = 444N
2. f = 82 * 450
f = 36900N
3. f = m*a
1800=53*a
a=1800/53

Find domain of the following functions
The domain of the function g (x) = (x² - 2 x - 15) / (x² + x - 6) is R - {-3, 2}.
We are given a function:
g (x) = (x² - 2 x - 15) / (x² + x - 6)
We need to find the domain of the function.
We know that a function becomes not defined when the denominator becomes 0.
Put x² + x - 6 = 0
x² + 3 x - 2 x - 6 = 0
x (x + 3) - 2( x + 3) = 0
( x + 3 ) ( x - 2 ) = 0
We get x = - 3 and x = 2.
So, these cannot be the values of x
So, the domain is
Domain = R - {-3, 2}
Therefore, the domain of the function g (x) = (x² - 2 x - 15) / (x² + x - 6) is R - {-3, 2}.

The area of Circle is 15∧2*π
Hence option A is correct.
According to the question the diameter of circle is 30 meters
we know,
diameter = radius*2
by using this we can say that the radius of the circle is 30/2
that is R = 15 meters
now According to the formula
Area of Circle = R*R*π
Putting the value of R into the formula by Substitution method
Area of circle = 15*15*π

Describe the similarities and differences between finding the slope of a linear equation from a graph that has x and y scales that are 1:1, and from a graph that has x and y scales that are not 1:1 (say your x and y scales are 2, 4, 6).
Using linear function concepts, we have that:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points in a graph, the slope is given by change in y divided by change in x, hence:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.More can be learned about linear function concepts at https://brainly.com/question/24808124

Write an equation for the line, in point-slope form, that passes through the following points. (2,-1) (5,-7)
Answer: y + 1 = -6(x-2)
Step-by-step explanation:
First find the slop with m = y2 - y1 / x2 - x1
-7 - (-1)/ 5 - 2 = -6
-7 + 1 / 5 -2 = -6
m = -6
Then use the point slope form y - y1 = m(x - x1) with coordinates (2, -1)
y - (-1) = -6(x - 2)
y + 1 = -6(x-2)
Write the equation of the line that is parallel to the given line and passes through the given point
The slope of parallel lines is the same, which is y = 5x - 12.
Parallel lines have the same slope in two dimensions. If we are aware of a point on the line and the equation of the supplied line, we can construct the equation of a line that is parallel to the given line.
Given: a line or point with a slope of m (x - x1), where m is the slope, and (x1,y1) is a point on the line, we obtain
y - (-1) = m (x - 2), and now the line is parallel to the one that was supplied. The slope is the SAME for parallel lines.
y + 2 = 5 (x - 2)
A line with a slope of y + 2 = 5x - 10 points...
Y = 5x – 12 – 2 – Subtract 2 from both sides.
Hence, the equation of the line that is perpendicular to the provided line and passes through has the form y = 5x – 12.
