Write an algebraic equation to match each graph. (These graphs are not drawn to scale!)
Answer:
y = |x - 1|
Step-by-step explanation:
This graph is the standard graph of y = |x|, shifted 1 unit right. To shift 1 unit right, we have to replace x by x - 1. This works because it replaces f(1) with f(0), f(2) with f(1), etc., shifting the entire graph right.
A florist uses 10 red roses for every 2 white roses in her bouquets. If the florist uses 10 white roses in an arrangement, how many red roses does she use?
Answer:
100
Step-by-step explanation:
dont know how to explain it.
Answer:
50
Step-by-step explanation:
If the florist uses ten red for every 2 white then take ten divided by 2 because 10 for every 2 then multiply 5 by 10.
for each of the figures write the absoloute value equation

Step-by-step explanation:
A rectangular prism is 2 inches by 4 inches by 6 inches.
Kimaya says, “It takes more 2/5-inch cubes to fill the prism than 1/5-inch cubes.”
Do you agree with Kimaya? Explain or show your reasoning.
No, I do not agree with Kimaya. The volume of the rectangular prism is 2 inches x 4 inches x 6 inches = 48 cubic inches. To fill the rectangular prism with 2/5-inch cubes, you would need 48 cubic inches / (2/5) cubic inches per cube = 120 cubes. To fill the rectangular prism with 1/5-inch cubes, you would need 48 cubic inches / (1/5) cubic inches per cube = 240 cubes.
So, it takes less 2/5-inch cubes to fill the prism than 1/5-inch cubes.
Another way to think of it is that the larger the cubes, the less number of cubes you need to fill the same volume, as the cubes are larger in size.

-2(4r - 6) Mathhhhhhhhh pls
Answer: -8r+12
Step-by-step explanation:
============================================
Explanation:
The outer term -2 is multiplied by each term inside
-2 times 4r = -8r-2 times -6 = 12Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.
I used the distribution property, also known as the distributive property.
That says a*(b-c) = a*b - a*c
In this case, a = -2, b = 4r, and c = 6.
A triangle has sides with lengths 5, 6, and 7. Is the triangle right, acute, or obtuse? Question 2 options: A) Obtuse B) Right C) Can't be determined D) Acute
Answer:
D: Acute triangle
Step-by-step explanation:
First check whether this could be a right triangle. Using the Pythagorean Theorem, we get:
5^2 + 6^2 = ? = 7^2 This equation is not true, and therefore the triangle is not a right triangle.
The side lengths 5, 6 and 7 are very close to one another, and so the triangle must have essentially similar interior angles, which means that all three angles are acute. Answer D is correct: This is an acute triangle.
Answer: D) Acute

Suppose f(x) is a function such that if p
f(x) can be odd or even.
f(x) can be odd but cannot be even.
f(x) can be even but cannot be odd.
f(x) cannot be odd or even.
Answer:
f(x) can be odd or even.
Step-by-step explanation:
The following information is missing in the question:
Suppose f(x) is a function such that if p < q, f(p) < f(q). Which statement best describes f(x)?
With the information given it is not possible to determine if the function is even or odd.
Even functions: f(-x) = f(x). For examle, (-2)² = 2², then x² is even
Odd functions: f(-x) = -f(x). For examle, (-2)³ = -(2³), then x³ is odd
In both cases, x² and x³, if p < q, f(p) < f(q). For example, 1² < 2², and 1³ < 2³
Hi my lovely people!
Today's question is math!
There are 2 screenshots below of my work!
(P.S its due today so yeah i will give brainlist too!)
Answer:
Part 1:
A - (4,9)
B - (6,3)
C - (1,3)
D - (8,7)
E - (8,9)
To know where to put the dots on the graph, use the coordinates you've just been given:
Example: (4,8)
Move to the 4 on the x-axis (the line on the bottom going horizontal)
Then, move up 8 units (up to the 8 on the y-axis)
Place the point at that spot.
Part 2:
A - (1,2)
B - (2,4)
C - (3,6)
D - (4,8)
Derek decorates 10 cookies in 5 minutes. We know he took 5 minutes to decorate 10 cookies because in the table, the x-axis is told to us that it represents the time it takes. Since the x coordinate is 5 in the point (5,10) and the y coordinate is 10, we can safely say that it took Derek 5 minutes to decorate 10 cookies.
From a log of wood of length (8x+12) m, a piece of length (4x+3) m was cut. Find the length of the remaining log of wood.
Grade#7
Answer: 4x+9
Step-by-step explanation: (8x+12)- (4x+3)
Answer: (4x+9)
Step-by-step explanation:
Log of wood = (8x+12)
piece length = (4x+3)
So, (8x+12) - (4x+3)
=> (8x+12) - 4x - 3
=> 8x-4x +12 -3
=> 4x + 9
So, the length of the remaining piece of wood = (4x+9)

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day
