[tex]\frac{x+1}{x-2}-\frac{x-3}{x+2}=0[/tex]
Answer:
[tex]x=\frac{1}{2}[/tex] or 0.5 in decimal form
Step-by-step explanation:
The expression is [tex]\frac{x+1}{x-2}-\frac{x-3}{x+2}=0[/tex]
Find Least Common Multiplier (LCM) of the denominators [tex]x-2,\:x+2[/tex]
This is [tex](x-2)(x+2)[/tex] the product of the two denominators
Multiply entire equation by this LCM: [tex](x-2)(x+2)[/tex]
We get
[tex]\frac{x+1}{x-2}\left(x-2\right)\left(x+2\right)-\frac{x-3}{x+2}\left(x-2\right)\left(x+2\right)=0\cdot \left(x-2\right)\left(x+2\right)[/tex]
Simplify the first term
[tex]\frac{x+1}{x-2}\left(x-2\right)\left(x+2\right)[/tex] [tex]=\left(x+1\right)\left(x+2\right)[/tex]
Simplify the second term
[tex]-\frac{x-3}{x+2}\left(x-2\right)\left(x+2\right) =\quad -\left(x-3\right)\left(x-2\right)[/tex]
RHS is [tex]0[/tex]
Therefore we get
[tex]\left(x+1\right)\left(x+2\right)-\left(x-3\right)\left(x-2\right)=0[/tex]
Expand the first term using the FOIL method [tex](x+a) (x + b) = x^2 + ax + bx + ab[/tex]
Here a = 1, b = 2. So [tex](x+1)(x+2) = x^2 + 2x + 1x + (1)(2) = x^2 + 3x + 2[/tex]
[tex]\left(x+1\right)\left(x+2\right)[/tex][tex]=x^2+3x+2[/tex]
Expanding [tex]-\left(x-3\right)\left(x-2\right)[/tex] gives us [tex]-x^2 + 5x - 6[/tex]
(Use the FOIL method: [tex](x+b) (x + a) = x^2 + ax + bx + ab[/tex] Here a = -2, b = -3. Note there is a negative sign before the entire expression)
So the original expression is
[tex]x^2+3x+2-x^2+5x-6 = 0[/tex]
Collecting like terms
[tex]x^2-x^2 + 3x +5x + 2 - 6[/tex] [tex]= 8x -4[/tex] = [tex]0[/tex]
Add 4 to both sides
[tex]8x-4+4=0+4[/tex]
[tex]8x=4[/tex]
Divide both sides by 8:
[tex]\frac{8x}{8}=\frac{4}{8}[/tex]
[tex]x=\frac{1}{2}[/tex] or [tex]0.5[/tex] in decimal
A washer and a dryer cost $995 combined. The washer cost $45 more than the dryer. What is the cost of the dryer?
When a washer and a dryer cost $995 combined. If the washer cost $45 more than the dryer, then the cost of the dryer is $475
The combined cost of a washer and a dryer = $995
Consider the cost of a dryer as x
The washer cost $45 more than the dryer.
The cost of the washer = x+45
Then the equation will be
x+x+45 = 995
2x+45 = 995
2x = 950
x = 950/2
x = 475
The cost of the dryer is $475
Hence, when a washer and a dryer cost $995 combined. If the washer cost $45 more than the dryer, then the cost of the dryer is $475

Find the measure of the missing angles.

e
d

f
f=
Step-by-step explanation:
e = 129° ( being vertically opposite angle )
Now ,
f + 129° = 180° ( being the angle in linear pair )
Again ,
d + 90° = 180° ( being the angle in linear pair )
d = 180° - 90°
d = 90°
☘️☘️☘️ ...
Answer:
d = 90° , e = 129° , f = 51°
Step-by-step explanation:
d and 90° are a linear pair and sum to 180° , that is
d + 90° = 180° ( subtract 90° from both sides )
d = 90°
e and 129° are vertically opposite angles and are congruent , then
e = 129°
f and 129° are a linear pair and sum to 180° , that is
f + 129° = 180° ( subtract 129° from both sides )
f = 51°

What is the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes
through the point (7,-6)?
Considering the definition of perpendicular line, the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes through the point (7,-6) is -8.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Perpendicular linePerpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.
Equation of perpendicular line in this caseIn this case, the line is 7x+2y=14. Expressed in the form y = mx + b, you get:
2y= 14 - 7x
y= (-7x + 14)÷ 2
y= -7/2x - 7
If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of -7/2. So:
-7/2× slope perpendicular line= -1
slope perpendicular line= (-1)÷ (-7/2)
slope perpendicular line= 2/7
So, the perpendicular line has a form of: y= 2/7x + b
The line passes through the point (7,-6). Replacing in the expression for perpendicular line:
-6= 2/7× (7) + b
-6= 2 + b
-6 -2 = b
-8= b, being b the y-intercept of the line.
Finally, the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes through the point (7,-6) is -8.

Any 1 of the following transformations will work. There are others that are also possible.
translation up 4 units, followed by rotation CCW by 90°.
rotation CCW by 90°, followed by translation left 4 units.
rotation CCW 90° about the center (-2, -2).
Step-by-step explanation:
The order of vertices ABC is clockwise, as is the order of vertices A'B'C'. Thus, if reflection is involved, there are two (or some other even number of) reflections.
The orientation of line CA is to the east. The orientation of line C'A' is to the north, so the figure has been rotated 90° CCW. In general, such rotation can be accomplished by a single transformation about a suitably chosen center. Here, we're told there is a sequence of transformations involved, so a single rotation is probably not of interest.
If we rotate the figure 90° CCW, we find it ends up 4 units east of the final position. So, one possible transformation is 90° CCW + translation left 4 units.
If we rotate the final figure 90° CW, we find it ends up 4 units north of the starting position. So, another possible transformation is translation up 4 units + rotation 90° CCW.
Of course, rotation 90° CCW in either case is the same as rotation 270° CW.

Answer:
In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation i2 = −1; every complex number can be expressed in the form a + bi, where a and b are real numbers. Because no real number satisfies the above equation, i was called an imaginary number by René Descartes. For the complex number a + bi, a is called the real part and b is called the imaginary part. The set of complex numbers is denoted by either of the symbols {\displaystyle \mathbb {C} }\mathbb {C} or C. Despite the historical nomenclature "imaginary", complex numbers are regarded in the mathematical sciences as just as "real" as the real numbers and are fundamental in many aspects of the scientific description of the natural world.[1][a]

A statistical tool used to synthesize the results of previous, separate studies is called a(n)?
A statistical tool used to synthesize the results of previous, separate studies is called a(n):Odds-ratio.
We know that, the odds ratio is one that is often calculated with the use of the number of case-patients who were or were not exposed to a factor (e.g. as a particular cream) and the number of controls that did or did not have the exposure.
Odds ratio is nothing but is a measure of association between exposure and an outcome.
It calculates the relationship between a variables and the likelihood of an event occurring.
Note that there are different kinds of statistical tool that are used for research purpose.

If cos(t) = 2/9 and t is in the 1st quadrant, find sin(t)
Answer:
Step-by-step explanation:
We can start by solving for t using the fact that [tex]cos(t) = \frac{2}{9}[/tex].
[tex]t = cos^{-1}(\frac{2}{9}) = 77.16\\[/tex]
then using that value of t solve for sin(t)
sin(t) = 0.975
As cos(t) is given and t is in the first quadrant then sin(t) will be equal to 8.77/9.
What is an expression?If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.
The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. In order to include terms in an expression, a mathematical operation like reduction, addition, multiplication, or division is used.
As per the information in the question,
cos(t) = 2/9
As we know that cos θ = B/H
B = 2 and H = 9
Now, use Pythagoras's theorem,
H² = P² + B²
P² = 9² - 2²
P = √77
P = 8.77
We also know that sin θ = P/H
So, sin(t) = 8.77/9
