Answer:
y= -9x - 6
Step-by-step explanation:
As x goes up by 1, y goes down by 9. We know that this is linear, not exponential.
Pick two points to find m, the slope.
(-1, 3) and (0, -6)
-9/1 = -9 as predicted
y = -9x + b
Plug in another point, such as (-1, 3)
3 = 9 + b
b = -6
EQUATION:
y= -9x - 6

A rectangular photo has a perimeter of 60 inches. If the length is twice the width,
find the length and width of the photo.
Answer:
length = 20 inches
width = 10 inches
Step-by-step explanation:
Perimeter = twice the length plus twice the width
60 = 2(2x) + 2(x)
60 = 4x + 2x
60 = 6x
x = 10
2x = 20
Answer:
length = 20 inches
width = 10 inches
Step-by-step explanation:
Perimeter = twice the length plus twice the width
60 = 2(2x) + 2(x)
60 = 4x + 2x
60 = 6x
x = 10
2x = 20
One fragment of a given integer N can be selected and its digits reversed (replaced with a right to left version of themselves). What is the maximum number that can be obtained this way from integer N
Integers are numbers without decimal points. The number could be positive, negative or zero
How to determine the maximum number from the integerThe maximum number from integer N can be determined using the following program written in Python, where comments are used to explain each line
#This prompts the user for input
num = input("Number: ")
#This iterates from 0 to 9
kount = [0 for x in range(10)]
# This iterates through the input, and updates the kount variable
for i in range(len(num)):
kount[int(num[i])] = kount[int(num[i])] + 1
# This next two lines initialize the greatest number
greatestNum = 0
multiplier = 1
# This iterates through the kount array
for i in range(10):
#The following is repeated while the current element is greater than 0
while kount[i] > 0:
#This generates the greatest number
greatestNum = greatestNum + ( i * multiplier )
kount[i] = kount[i] - 1
multiplier = multiplier * 10
#This prints the greatest number
print(greatestNum)

A robot can complete 7 tasks in
5/6 hour. Each task takes the same amount of time.
a. How long does it take the robot to complete one task?
b. How many tasks can the robot complete in one hour?
Answer:
5/42 is your answer take robot to complete
7 tasks = 5/6
1 task = 5/42 hour.
1 hour / (5/42 hour/task) = 15/2 tasks = 8.2 tasks.
half a task isn’t a complete task, so the answer is 8 tasks.
Gwen is building a wooden birdhouse for her mom. She finds a plank in the garage to use for
the base. When she realizes it's too long, Gwen cuts 2 inches off the plank. Now it's the
correct length of 9.75 inches.
Which equation can you use to find the length p of the plank before Gwen cuts it?
Answer:
p = 11.75 - 2 = 9.75
Explanation:
2 + 9.75 = 11.75, which was the original length of the plank, therefore:
11.75 - 2 = the correct and current length of the plank

The formula f(x) = 9x converts square yards to square feet. a. Find the inverse f–1(x). What is the significance of f–1(x) for the Clearys? b. What will the new flooring cost the Clearys?
The inverse of the function for square feet, gives the area in square yard
from which the cost of the flooring is calculated as $539.7.
Response:
a. The inverse [tex]\underline{f^{-1}(x) = \dfrac{x}{9}}[/tex] can be used by the Clearys to calculate the cost if the flooring.
b. $539.7
What is the inverse of a function and how can it be used?Given:
The dimensions of the flooring = 15 foot by 18 foot
Cost of the new flooring = $17.99/yd.²
The formula that converts square yards to square feet is f(x) ≈ 9·x
a. The inverse function gives the x-values as an output from an input of
the y-value.
The inverse of the function, f⁻¹(x), is the function that converts square
feet to square yards, which is given as follows;
[tex]\underline{f^{-1}(x) = \dfrac{x}{9}}[/tex]The significance of f⁻¹(x) for the Clearys is that it gives the number of
square yards required for the flooring from the square feet, from which
the cost of the flooring can be calculated.
b. The cost of the new flooring is therefore;
[tex]Cost = \$17.99/yd.^2 \times f^{-1}(x) = \$17.99/yd.^2 \times \dfrac{15 \, ft. \times 18 \, ft. }{9} = \mathbf{\$539.7}[/tex]

A museum exhibit hall is the shape of a regular octagon. The distance between any two parallel walls is 30 feet. What is the perimeter of the exhibit hall, rounded to the nearest foot?
The perimeter of the hall is the sum of its side lengths.
The perimeter of the museum exhibit hall is 240 feet
How to determine the perimeterFrom the question, we understand that the shape of the museum exhibit hall is a regular octagon
The perimeter of a regular octagon is:
p = 8l
Where l represents the side length of the octagon
So, we have:
p = 8 * 30 feet
Evaluate the product
p = 240 feet
Hence, the perimeter of the exhibit hall is 240 feet

From our lesson, what is your difficulty in dealing with exponential expressions?
Answer:
From the said lesson, the difficulty that I have been trough in dealing over the exponential expressions is the confusion that frequently occurs across my system whenever there's a thing that I haven't fully understand. It's not that I did not actually understand what the topic was, but it is just somewhat confusing and such. Also, upon working with exponential expressions — indeed, I have to remember the rules that pertain to dealing with exponents and frequently, I will just found myself unconsciously forgetting what those rule were — rules which is a big deal or a big thing in the said lesson because it is obviously necessary/needed over that matter. Surely, it is also a big help for me to deal with exponential expressions since it's so much necessary — it's so much necessary but I keep fogetting it.. hence, that's why I call it a difficulty. That's what my difficulty. And in order to overcome that difficulty, I will do my best to remember and understand well the said rules as soon as possible.
The base of a triangle is X inches the area is 14 in.² what is the height of the triangle
Step-by-step explanation:
the base is x in.
the area is 14 in².
the area is calculated by :
base × height / 2
so, we have here
14 = x × height / 2
28 = x × height.
height = 28/x in.

Solve for x and y. State answers in simplified radical form, please.
Answer:
x=8√3 units
y=4√3 units
Step-by-step explanation:
Since the given right triangle happens to be a 30-60-90 triangle, we will use the following rules:
Hypotenuse = 2s (x)
Longer Leg = s√3 (12)
Shorter Leg = s (y)
Since the longer leg is given to us as 12 units, we can then solve for the shorter leg:
12 = s√3
12/√3 = s
(12√3)/3 = s
4√3 = s
Therefore, our hypotenuse is 2(4√3) = 8√3 units
Thus, x=8√3 units and y=4√3 units
