2x-9=5x what is the value of x
The value of 'x' of the given equation 2x - 9 = 5x is -3.
What exactly is an equation?In its most basic form, an equation is a mathematical statement that proves two mathematical expressions seem to be equal.3x + 5 = 14 is an equation in which the expressions 3x + 5 and 14 are kept separate by an equal sign.
So,
2x - 9 = 5x2x - 5x = 9- 3x = 9x = -9/3x = -3/1x = -3Therefore, the value of x of the given equation is -3.

What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
We have to given the function is,
3 (x - 2) - 4 (x + 1) = -22
Now, We can solve the expression as,
3 (x - 2) - 4 (x + 1) = -22
Use Multiplicative property;
3x - 6 - 4x - 4 = -22
Use addition and subtraction property,
- x - 10 = - 22
Use addition property and Add 22 both sides;
- x - 10 + 22 = - 22 + 22
- x + 12 = 0
Use subtraction property, Subtract 12 both sides;
- x + 12 - 12 = 0 - 12
- x = - 12
Multiply by -1 in both sides,
x = 12
Therefore, The solution of the equation 3 (x - 2) - 4 (x + 1) = -22 is,
⇒ x = 12

A triangle contains vertices A (-3, 2), B (1, 2), and C (-4,-2).
If AABC is rotated 90° counterclockwise around the origin, what are the coordinates of the transformed figure AA'B'C'?
The coordinates of the triangle A'B'C' which is rotated 90° counterclockwise is A' (-2,-3) , B' (-2,1) , and C' (2,-4).
When the points are rotated 90° counterclockwise then the new coordinates will be transformed to
(x , y ) = (-y , x)
According to the question we have been the coordinates of the ΔABC which are :
A = (-3,2) , B = (1,2) and C = (-4,-2)
When the triangle is rotated 90° counterclockwise the new coordinates will become
A' = (-2,-3)
B' = (-2,1)
C' = (2,-4)
Hence the coordinates of the triangle A'B'C' which is rotated 90° counterclockwise is A' (-2,-3) , B' (-2,1) , and C' (2,-4).

It will take 138 minutes for the repair cost to reach $140
Although part of your question is missing, you might be referring to this full question: A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 +0.617x. Where y is the number of dollars charged and x is the number of minutes the repair person is on the job. how many minutes would it take for the cost of repair to reach $140? (round to the nearest minute.)
As per the question:
Number of dollars charged by the company = y dollars
Number of minutes the repair person is on the job = x minutes
The cost that needs to be achieved = 140 dollars
Equation:
y = 47.38 + 0.617x------(1)
For the cost of repair to reach $140, substituting $140 in y in equation (1)
140 = 47.38 + 0.617x
Solving further and finding the value of x
140 - 47.38 = 0.617x
92.62 = 0.617x
x = 138 minutes (rounded to the nearest minute)
So, it will take 138 minutes for the repair cost to reach $140

Answer:
(- 4, 2 )
Step-by-step explanation:
y = 3x + 14 → (1)
2x - 3y = - 14 → (2)
substitute y = 3x + 14 into (2)
2x - 3(3x + 14) = - 14 ← distribute parenthesis on left side and simplify
2x - 9x - 42 = - 14
- 7x - 42 = - 14 ( add 42 to both sides )
- 7x = 28 ( divide both sides by - 7 )
x = - 4
substitute x = - 4 into (1)
y = 3(- 4) + 14 = - 12 + 14 = 2
solution is (- 4, 2 )
h(x) = ³√x - 3 write the inverse given the function
The inverse of the function h(x) = ³√x - 3 is h⁻¹(x) = (x + 3)³.
What is termed as the inverse of the function?An inverse function is one that reverses the action of another function. A function g has become the inverse of a function f when and only when y=f(x) and x=g (y). In other words, using f and then g is equivalent to doing nothing. This can be written as g(f(x))=x in terms of the combination of f and g.The given function is-
h(x) = ³√x - 3
Put y = h(x);
h(x) = y = ³√x - 3
Make x the subject;
x = (y + 3)³
Replace x with h⁻¹(y) = (y + 3)³
Restate with x instead of y.
h⁻¹(x) = (x + 3)³
Thus, the inverse of the function h(x) = ³√x - 3 is h⁻¹(x) = (x + 3)³.

When a patient with hypertension takes a particular type of blood pressure medication, the effects on the systolic pressure, S(t), can be measured by the following piecewise defined function: S of t is equal to the piecewise function of 140 minus 6 times t if 0 is less than or equal to t is less than or equal to 4 and 116 if 4 is less than t is less than 8 and 96 plus 8 times t if 8 is less than or equal to t is less than or equal to 12 where t is the time, in hours, since taking the medication. Based on the graph of the piecewise function, if the patient takes the blood pressure medication at 8 a.m., in which interval will their systolic pressure be lowest?
The interval where the systolic pressure will be lowest is from 12 PM to 2 PM.
What are the domain and ranges of a function ?
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.
A function S(t) is defined for systolic pressure.
S(t) = { 140 - 6t , for 0 ≤ t ≤ 4 }
S(t) = { 116 , for 4 < t < 8 }
S(t) = {96 + 8t , for 8 ≤ t ≤ 12 }
Let's find the values of systolic pressure [tex]S(t)_{min}[/tex] for each cases.
When , 0 ≤ t ≤ 4
[tex]S(t)_{min}[/tex] = 140 - ( 6 × 4 )
[tex]S(t)_{min}[/tex] = 140 - 24
[tex]S(t)_{min}[/tex] = 116
When , 4 < t < 8
[tex]S(t)_{min}[/tex] = 116
When , 8 ≤ t ≤ 12
[tex]S(t)_{min}[/tex] = 96 + ( 8 × 8)
[tex]S(t)_{min}[/tex] = 96 + 64
[tex]S(t)_{min}[/tex] = 160
So , the lowest value of S(t) will be 116 for for 4 < t < 8 and interval will be from 12 PM to 2 PM.
Therefore , the interval where the systolic pressure will be lowest is from 12 PM to 2 PM.

Step-by-step explanation: 24 out of 30 is 80.00%.
Step 1: We make the assumption that 30 is 100 % since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100 % = 30.
Step 4: In the same vein, x % = 24 .
Step 5: This gives us a pair of simple equations:
100 % = 30(1).
x % = 24(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100 % / x % = 30/24
Step 7: Taking the inverse (or reciprocal) of both sides yields
x/100 = 24/30
x = 80 %

Answer:

Step-by-step explanation:
Given graphed inequalities and a list of points, you want the point that is a "solution."
AssumptionsWe assume the graphed inequalities are part of a system of two inequalities and that a "solution" is one that must satisfy both of them. Any solution point will be in the doubly-shaded area, or on the solid blue boundary next to that area.
SolutionEach of the given points is 6 units from the origin on one of the coordinate axes. The only such point that lies in the doubly-shaded area is (-6, 0) on the negative x-axis.
The point (-6, 0) is a solution.
__
Additional comment
We know the kinds of inequalities that can give rise to a graph like this, but we don't know the question for which one of these points would be a solution. That is why assumptions are necessary.
The point (0, 6), for example, could be a solution to the question, "what set of values satisfies x-y ≤ 1, but not x+y < 3?"
