We know from a real number line that we cannot have imaginary numbers. Therefore, we cannot have any negatives under the square root.
Our domain for our integrated function would then have to be (-∞, 400]. Anything past 400 would give us an imaginary number.
Write in standard form the equation y - 9 = 1/3(x - 6).

First make slope intercept
y = 1/3(x - 6) + 9
y = 1/3x - 2 + 9
y = 1/3x + 7

how do you find the y-intercept?
Answers
Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
so to find that you can use y=mx+b, or you can use point slope form and that would be y-y1+m(x-x1)
remember m= slope b= y- intercept

The length of a rectangle is twice its width, while the
perimeter of the rectangle is 36 units. . Which system of
equations can be used to find the length ( and the width w
of the rectangle?
Answers
Answer: Length = 12 units
Width = 6 units
Step-by-step explanation:
Let the width of the rectangle be represented by x.
Since the length of a rectangle is twice its width, thus means that the length will be: = 2x
Perimeter of a rectangle = 2(l + w)
where,
L = length
W = width
Therefore,
Perimeter = 2(l + b)
36 = 2(2x + x)
36 = 2(3x)
36 = 6x
x = 36/6
x = 6
Width = 6 units
Length = 2 × Width = 2 × 6 = 12 units

Is the relation a function? If it is a function, state the domain and range. If not, circle or
highlight the part that causes it to not be a function.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Writing this relation in set notation using curly braces:
{(1, 3), (2, 5), (3, -1), (4, 0), (5, 6)}
The relation clearly indicates that each input is related to exactly one output. In other words, there is no repetition of 'x' values.
Hence, this relation is a function.
We know that the domain is the set of all x values.
Thus, the domain is: {1, 2, 3, 4, 5}
We know that the domain is the set of all y values.
Thus, the range is: {-1, 0, 3, 5, 6}

A bag contains five ping-pong balls numbered 1 to 5. Two balls are removed to form a two digit number. The smallest possible number is 12 and the largest is 54. What is the probability that the number formed is prime? (hint: Write out the entire sample space)
Answers
Answer:
[tex]\frac{11}{42}[/tex] or 26.19%
Step-by-step explanation:
If the range of possible numbers is between 12 and 54 then that means that there are 42 (54 - 12) possible numbers that can be made. In this range, there are 11 prime numbers which are the following...
13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53
Therefore, the probability that the number formed is a prime would be [tex]\frac{11}{42}[/tex] which if we divide and multiply the decimal by 100 we get the probability in percentage form.
[tex]\frac{11}{42}[/tex] = 0.2619
0.2619 * 100 = 26.19%
Finally, we can see that the probability of this happening is 26.19%

An oil drilling company drills the same distance each day for 5 days. They started at an elevation of 121.175 feet and ended at an elevation of -246.875 feet. Which equation can be used to find x, the distance they drilled each day?
Answers
Answer:
[tex]x=\dfrac{|-246.875-121.175|}{5}[/tex]
Step-by-step explanation:
Given that:
Same distance is drilled by the oil drilling company for 5 days.
Initial elevation = 121.175 feet
Final elevation = -246.875 feet
To find:
The equation to find the value of [tex]x[/tex] i.e. the distance drilled each day?
Solution:
To find the distance drilled each day, we need to divide the total distance drilled with the number of days taken to drill the total distance.
Total distance drilled can be found by subtracting the initial elevation from the final elevation and taking modulus because distance can not be negative.
Total distance drilled = | Final elevation - Initial elevation |
Total distance drilled = | -246.875 - 121.175 |
Therefore, we can write the expression as:
[tex]x=\dfrac{|-246.875-121.175|}{5}[/tex]
[tex]\Rightarrow x=\dfrac{|-368.05 |}{5} =73.61\ ft/day[/tex]
what numbers must be added to complete the perfect square?
Answers
Answer:
256
Step-by-step explanation:
Let the number be k
Thus, the equation can be written as:
x² – 32x + k
From the above,
a = 1
b = –32
c = k
The value of k can be obtained as follow:
b² = 4ac
(–32)² = 4 × 1 × k
1024 = 4k
Divide both side by 4
k = 1024 / 4
k = 256
Thus, 256 should be added to x² – 32x to make it a perfect square i.e
x² – 32x + 256
****Check****
x² – 32x + k
k = 256
x² – 32x + 256
x² – 16x – 16x + 256
x(x – 16) – 16(x – 16)
(x – 16)(x – 16)
