What is the inverse of the function f(x) = 2x – 10?
Oh(x) = 2x-5
O h(x) = 2x + 5
O h(x) =
X-5
h(x) = 3x -
h(x) = 2x +
x5
o hx
Answer:
Last Option
Step-by-step explanation:
Step 1: Write function
f(x) = 2x - 10
y = 2x - 10
Step 2: Swap
x = 2y - 10
Step 3: Solve for y
x + 10 = 2y
y = x/2 + 5
f⁻¹(x) = x/2 + 5

Step-by-step explanation: 2(x=3) = 6(2) 12 + 5 = 17.
The two forms of equations are identity equations and conditional equations.
By substituting the value of x=3, then we get 23.
What is meant by an equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
The two forms of equations are identity equations and conditional equations. All feasible values of the variables share the same identity. Only specific instances where the values of the variables coincide can result in the truth of a conditional equation. Two phrases exists connected into one by utilizing the equals sign ("=").
Let the equation be 2x² + 5
Substitute the value of x = 3, then we get
2(3)² + 5 = 23
Therefore, the value be 23.

Step-by-step explanation:
just break it up
The factor of the given number are 180 = 7 x 2 x 2x 2
What is prime factorization?Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.
For an integer, factorization is decomposition of that integer in terms of smaller integers which when multiplied with each other give back that considered number. Those composing integers are called factors of that considered integers.
The Prime factorization is when all those factors are prime numbers, prime factorization expresses an integer in terms of multiples of prime numbers.
Prime factorization is unique for each integer.

Answer:

Step-by-step explanation:
the perimeter of a rectangular floor is 100 feet . Find the dimensions of the floor , if the length is four times the width
Width = 10 feet
Length = 40 feet
================================================
Explanation:
W = width
L = 4W = four times the width = length
P = perimeter
P = 2*(W+L)
P = 2*(W+4W)
P = 2(5W)
P = 10W
The perimeter is 100 feet.
P = 100
10W = 100 .... plug in P = 10W
W = 100/10 .... divide both sides by 10
W = 10
The width is 10 feet.
L = 4W
L = 4*10
L = 40
The length is 40 feet.
-----------------
Check:
P = 2(L+W)
P = 2(40+10)
P = 2(50)
P = 100
or another way to check is to add up the four sides {10, 40, 10, 40}
10+40+10+40 = 50+50 = 100
This confirms the answer.
Answer:
Width = 10 feetLength = 40 feetStep-by-step explanation:
Perimeter (P) = 2L + 2W
where
P = 100 feet
L = 4W
plugin values into the formula:
100 = 2(4W) + 2W
100 = 8W + 2W
100 = 10W
W = 100/10
W = 10 feet
L = 4W
L = 4(10)
L = 40 feet
P = 2(40) + 2(10)
P = 80 + 20
P = 100

Answer:
(3x + 5) + (x +3) = 180 sum of angles on a
straight line
3x + 5 + x + 3 = 180
3x + x + 5 + 3 = 180
4x + 8 = 180
4x = 180 - 8
x = 172/4
= 43
The angles 3x + 5 and x + 3 are
3x + 5 = 3(43) + 5 = 129 + 5 = 134
x + 3 = 43 + 3 = 46

n(x)=−1−x+4 when x=−2,0, and 5
Answer:
-2
Step-by-step explanation:
n(-2) = -1 - (-2) + 4 = -1 + 2 + 4 = -1 + 6 = 5
( - 1 , 6 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [6] is +. So, result is 5)
n(0) = -1 - 0 + 4 = -1 + 4 = 3
n(5) = - 1 - 5 + 4 = -6 + 4 = -2
( -6 , 4 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [-6] is -. So, result is -2)

x^2-16x+48
Answer:
(x - 4)(x - 12)
Step-by-step explanation:
Given
x² - 16x + 48
Consider the factors of the constant term (+ 48) which sum to give the coefficient of the x- term (- 16)
The factors are - 4 and - 12, since
- 4 × - 12 = + 48 and - 4 - 12 = - 16 , thus
x² - 16x + 48 = (x - 4)(x - 12)
Answer:
the correct option is (x-4)(x-12)
Step by Step explanation:-
x^2-16x+48
x^2-12x-4x+48
by taking the common factor out,
x(x-12)-4(x-12)
