The value of the expression 3√63 +√28 is 5√7 or 13.228.
A number is a fundamental mathematical unit. For counting, measuring, and comparing quantities, we utilize numbers. A set of symbols, or numerals, used to represent numbers is known as a number system.
A square root is a factor of a number that yields the original number when multiplied by itself.
Consider the expression 3√63 +√28,
Let's assume x = 3√63 +√28
Now,
63 = 3 × 21 = 3 × 3 × 7
28 = 2 × 14 = 2 × 2 × 7
Therefore,
x = 3√63 +√28
x = √ [ 3 × 3 × 7 ] + √ [ 2 × 2 × 7 ]
x = ( √ 3² ) × ( √7 ) + ( √2² ) × √7
x = 3√7 + 2√7
x = ( √7 ) × [ 3 + 2 ]
x = ( √7 ) × 5
x = 5√7
x = 5 × 2.6457
x = 13.228
Hence, the value of 3√63 +√28 is equal to 13.228.

Find each composition of functions. Simplify your answer.
Let f(x)=1/x . Find f(f(f(x))) .
A composite function exists as a function that depends on another function. A composite function exists formed when one function exists substituted into another function.
The value of f(f(f(x))) is 1/x
What is meant by composition function?In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.
Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.
A function that depends on another function is referred to as a composite function. When one function is inserted into another, a composite function is produced. For instance, f(g(x)) is the composite function created when x in f is replaced with f(x). f(g(x)). You can interpret f(g(x)) as "f of g of x."
Let the given function be f(x) = 1/x
f(f(x)) = f(1/x) = 1/(1/x)
simplifying the above equation, we get
f(f(x)) = f(1/x) = x
f(f(f(x))) = f(x) = 1/x
Therefore, the value of f(f(f(x))) = f(x) = 1/x

b. The inverse of f₁(x)=b x-h is equivalent to a translation of g .
If b^{h} < 1 then it will be a vertical stretch.
What authority possesses a power rule?
When a base is raised to a power and then the entire expression is raised to another power, the power of a power rule in exponents is used to simplify the algebraic statement.
A translation of function f is f₁ (x) = bˣ⁻h . It is equivalent to a vertical stretch or vertical compression of function f.
[tex]f_{1} (x) = b^{x - h}[/tex]
If we used the rules of powers, we know that when we have a subtraction in the power of an exponential, it can be split into a division. So the function can be rewritten as
[tex]f_{1} (x) = \frac{b^{x} }{b^{h} }[/tex]
Remember the original function was
f(x) = bˣ
therefore
[tex]f_{1}(X) = \frac{f(x)}{b^{h} }[/tex]

What is the equation of the line that passes through the point (-3,7)(−3,7) and has a slope of -5/3
Step-by-step explanation:
what form should the equation have ?
I assume slope-intercept
y = ax + b
"a" being the slope, "b" being the y-intercept (the y value when x = 0).
but since we have the slope and a point, we can start with the point-slope form and transform it :
y - y1 = a(x - x1)
"a" is again the slope, (x1, y1) is the point.
so,
y - 7 = -5/3 × (x - -3) = -5/3 × (x + 3) = -5x/3 - 5
and therefore
y = -5x/3 + 2

Given the perimeter, the length and width of the rectangular family portrait are 20 inches and 31 inches respectively.
What is the length and width of the rectangular frame?The perimeter of a rectangle is expressed mathematically as;
P = 2( l + w )
Given the data in the question;
Let "x" represent the width of the rectangle.
Width w = xLength l = 2x - 9Perimeter P = 102 inchesTo determine the width and length of the rectangle, plug the given values into the formula above and solve for x.
P = 2( l + w )
102 = 2( ( 2x - 9 ) + x )
102 = 2( 2x - 9 + x )
102 = 2( 3x - 9 )
Apply distributive property
102 = 2(3x) + 2(-9)
102 = 6x - 18
102 + 18 = 6x
120 = 6x
6x = 120
x = 120/6
x = 20
Now, the numerical length and with of the rectangular frame will be;
Width w = x = 20 inches
Length l = 2x - 9 = 2(20) - 9 = 40 - 9 = 31 inches.
Given the perimeter, the length and width of the rectangular family portrait are 20 inches and 31 inches respectively.

The points (0, 0) and (1, 3) fall on a particular line. What is its equation in slope-intercept
form?
Answer:
y = 3x
Step-by-step explanation:
Slope-intercept form of an equation is a shortcut, fill-in-the-blank form you can use to write the equation of a line.
Slope-intercept eq:
y = mx + b
You fill in slope where the m is. And you fill in the y-intercept for the b.
In your problem they gave you two points. You can calculate slope with two points. Subtract the y's, 3-0, put that on top of a fraction. And subtract x's, 1-0, put that on the bottom of the fraction. The slope, m, is 3/1, which is 3.
slope:
m = 3-0 / 1-0 = 3/1 =3
The y-intercept is actually given in your problem. The y-intercept is the point where the line crosses the y-axis. The y-intercept is the point where the x is 0. They gave you the point (0,0) that is the y-intercept. So b = 0.

How to solve an equation?
To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.
