The domain and the range of its inverse function, h^-1( x) are x < 4 and y < 5
How to determine the domain and the range?The domain and the range of the function are:
x < 5 and y < 4
When the function is inverted, the domain becomes the range and vice versa.
This means that the domain and the range of its inverse function, h^-1( x) are x < 4 and y < 5

if there consecutive terms of an AP are k+2 ,4k -6 and 3k-2 . What is the value of k
===========================================================
Explanation:
A = first term = k+2B = second term = 4k-6C = third term = 3k-2To go from the first term to the second term, we add on some common difference d.
So,
B = A+d
B = (k+2)+d
4k-6 = k+2+d
4k-6-k-2 = d
d = 3k-8
---------------
Similarly, to go from the second term to the third term, we also add on d
C = B+d
C = (4k-6)+d
C = (4k-6)+(3k-8)
C = 7k-14
3k-2 = 7k-14
---------------
Let's solve for k
3k-2 = 7k-14
-2+14 = 7k-3k
12 = 4k
4k = 12
k = 12/4
k = 3 is the final answer
---------------
If k = 3, then we have these three terms:
A = k+2 = 3+2 = 5B = 4k-6 = 4(3)-6 = 6C = 3k-2 = 3(3)-2 = 7The arithmetic progression (AP) is 5, 6, 7. The common difference is d = 1.
Note how d = 3k-8 = 3(3)-8 = 1

Solve for the value of X. Round to the nearest whole number.
Answer:
x = 30º
Step-by-step explanation:
This answer requires trigonometry, specifically, the cosine function. This is because we are given the length of the side adjacent to x and the length of the hypotenuse.
If you recall:
[tex]cos(x )= \frac{adjacent}{hypotenuse}[/tex]
Therefore,
[tex]cos(x) = \frac{13}{35}[/tex]
Now, we must use the inverse cosine function on a calculator to figure out the value of x.
[tex]cos^{-1}(\frac{13}{15}) = 29.93[/tex]
Now, we must round it to the nearest whole number, so x = 30º.

A. (0, 10)
B. (10, 10)
C (V10,0)
D(V10,10
Answer:(0,10)
Step-by-step explanation:
The points On circle with a center at (0, 0) that includes the point (-1, -3) would be (0, 10).
What is the equation of the circle with radius r units, centered at (x,y) ?If a circle O has a radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane,
then, its equation is given as:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
We have given On circle with a center at (0, 0) that includes the point (-1, -3).
So the equation form
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
[tex](x-0)^2 + (y-0)^2 = r^2\\\\x^{2} +y^{2} =r^{2} \\\\(-1)^{2} +(-3)^{2} =r^{2} \\\\r^{2} = 10[/tex]
So, the other point that satisfies the equation would be (0, 10).

What is x?
Answer:
69/11
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x−3+2x−7+5x−1=58
4x+−3+2x+−7+5x+−1=58
(4x+2x+5x)+(−3+−7+−1)=58(Combine Like Terms)
11x+−11=58
11x−11=58
Step 2: Add 11 to both sides.
11x−11+11=58+11
11x=69
Step 3: Divide both sides by 11.
11x /11 = 69/11
Answer:
x = 69/11
Step-by-step explanation:
4x - 3 + 2x - 7 + 5x - 1 = 58 collect like terms ↓
11x - 3 - 7 - 1 = 58
11x - 11 = 58 move the constant to the right-hand side and change its sign ↓
11x = 58 + 11 add the numbers ↓
11x = 69 then divide both sides of the equation by 11 ↓
x = 69/11 ;)

A bag with 6 marbles is shown below. (3 marbles are red, 1 is yellow, and 2 are blue.) A marble is chosen from the bag at random. What is the
probability that it is red?
Write your answer as a fraction or a whole number.
Answer:The answer is 1/2 or you can do 3/6 if it doesnt need to be simplified
Step-by-step explanation:
Probability is the chance of an event to occur from a number of possible outcomes.
The probability that a marble chosen at random is red is 1/2.
What is probability?It is the chance of an event to occur from a number of possible outcomes.
It is given by:
Probability = Number of required events / Total number of outcomes
We have,
Total number of marbles in the bag = 6
Number of red marbles = 3
Number of yellow marbles = 1
The number of blue marbles = 2
The probability that a marble chooses is red:
= Number of red marbles / total number of marbles
= 3 / 6
= 1 / 2
Thus,
The probability that a marble chosen at random is red is 1/2.

A hotel has 480 rooms. Of these rooms,
are non-smoking. How many rooms are smoking?
Answer:
The number of smoking rooms [tex]N_s = \frac{480(100-x)}{100}[/tex], in which x is the percentage of non-smoking rooms.
Step-by-step explanation:
We are given a percentage of rooms that are non smoking, lets say x%, and (100-x)% will be smoking rooms. The number of rooms which are smoking is the total number of 480, multiplied by (100-x) and divided by 100.
