If , which equation describes the graphed function? A. y = f(-x) − 3 B. y = -f(x) + 3 C. y = -f(x) – 3 D. y = f(-x) + 3
Answer:
y=-f(x)-3
Step-by-step explanation:
when f is negative it is reflected over the x-axis and -3 means to translate 3 units down
y = -f(x) – 3 describes the graphed function.
When f is negative it is reflected over the x-axis.
-3 means to translate 3 units down.
How do you identify a function?By using inspecting the inputs (x-coordinates) and outputs (y-coordinates), you could decide whether or no longer the relation is a function. Keep in mind, that this is a feature each input has only one output.

The price of a holiday was decreased by 12% to £600. What was the price before the decrease?
Give your answer to the nearest penny
Need this ASAP thanks
Answer:
The original price of the holiday was $ 681.81.
Step-by-step explanation:
As the price of the holiday was reduced by 12% to a value of $ 600, it can be said that this price is 88% of its original price (100 - 12). Therefore, to determine the original price of the holiday, it is necessary to perform the following calculation:
88 = 600
100 = X
(100 x 600) / 88 = X
60,000 / 88 = X
681.81 = X
Therefore, the original price of the holiday was $ 681.81.

Natalee wanted to demonstrate the volume of a square pyramid. To do this, she took a hollowed out pyramid that has a base of 25 square inches and a height of 5 inches and filled it with water. She then dumped this water into a hollowed out cube that has a volume of 125 cubic inches. Enter the amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube
Answer:
The answer is below
Step-by-step explanation:
Natalee transferred water from a square pyramid to a cube. To calculate how many times she will need to dump the water from the pyramid into the cube to completely fill the cube, we divide the volume of the cube by the volume of the square pyramid. Hence:
Number of times = volume of cube / volume of pyramid
The perimeter of the pyramid base = 25 in, hence the length of one side of the bae = 25 / 4 = 6.25 in
Volume of square pyramid = base² × (height / 3) = (6.25 in)² * (5 in / 3) = 65.1 in³
Volume of cube = 125 in³
Number of times = 125 in³ / 65.1 in³ = 1.92
The amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube is 1.92.
What is volume?The capacity of a container of any shape is called the volume.
Natalee transferred water from a square pyramid to a cube. Then,
Given is the perimeter of the pyramid base = 25 in
So, the length of one side of the base b= 25 / 4 = 6.25 in
Volume of square pyramid = b² × (h/ 3) = (6.25 in)² * (5 in / 3) = 65.1 in³
Volume of cube = 125 in³
Number of times = volume of cube / volume of pyramid
Number of times = 125 in³ / 65.1 in³ = 1.92

Answer:
36
Step-by-step explanation:
x² + 12x - 40 = 0
x² + 12x = 40
Now, 12/2 = 6. So add 6² = 36 to each side
x² + 12x + 36 = 40 +36
What is the midpoint of the segment shown below ? A. (1,5) B. (2,5), C ( 1 1/2,5), D. (2 1/2, 5)
The midpoint of the line segment is (2,5) (option B)
How do you find the midpoint of a line segment in a coordinate?When given the end points of a line segment, you can find out its midpoint by using the midpoint formula. As the name might have already suggested, midpoint is basically the halfway between two end points. All you need to do is dividing the sum of x-values and the sum of y-values by 2.
The sum of x coordinate is -1+5 = 4
half of sum of x coordinate = 4/2 = 2
The sum of y coordinate = 5+5= 10
half of sum of y coordinate = 10/2 = 5
therefore the midpoint of the line is ( 2,5)

You work as a cashier for a grocery store and earn $5 per hour. You also mow lawns and earn $10 per hour. You want to earn at least $50
per week, but would like to work no more than 10 hours per week.
Which system of inequalities, along with y0 andx
0, would you use to solve the real-world problem?
The required inequalities are x + y ≤ 10 and 5x + 10y ≥ 50
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, You work as a cashier for a grocery store and earn $5 per hour. You also mow lawns and earn $10 per hour. You want to earn at least $50 per week, but would like to work no more than 10 hours per week.
Let, you work at grocery story (x), and you work mowing lawns (y)
You want to work no more than 10 hrs
So, first inequality will deal with hrs.
x + y ≤ 10....(i)
A less than or equal to sign tells that you do not want to work more than 10 hrs, but you can still work 10 hrs, so we include the equal sign as well.
And,
Grocery store (x) earning $5 per hr and lawn mowing (y) earning $10 per hr, making at least $50...
Now we will make an inequality dealing with the $
5x + 10y ≥ 50.....(ii)
A greater than or equal to sign tells that, you want to make 50 or more, so we include the equal sign.
So, the inequalities are :
x + y ≤ 10
5x + 10y ≥ 50

A bakery has 36 glazed donuts on display. This is 80% of the total number of donuts. What is the total number of donuts in the bakery?
Answer:
it is 64.8, but you have to round to the nearest number, so i would say 65 :)
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
% means out of 100, so 80% is 80/100
Let's divide 100/80 to find a scale we can use to multiply 36, 100/80 =
36 times 1.25 = 45
There's 45 donuts
Double check:
45(80/100) = 36, we're right
how to solve using Substitution or Elimination?
y=3x-1
y=2x+2
By elimination:
y = 3x - 1
y = 2x + 2
Subtract the second equation from the first
0 = x - 1
y = 2x + 2
Subtract the first equation from the second
0 = x - 1
y = x + 3
Subtract the first equation from the second again
0 = x - 1
y = 4
Subtract x from both sides of the first equation
- x = - 1
y = 4
Divide the first equation by (-1)
x = 1
y = 4
So, the solution is x = 1 and y = 4 {or: (1, 4)}
