Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = –8x + x2 + 7 ?
left 4, down 9
left 4, up 23
right 4, down 9<<<<<<< CORRECT
right 4, up 23
The translation should be right 4 units and down 9 units.
Which translation should we use?
First, we need to find the vertices of both functions.
for f(x) = x^2 the vertex is at (0, 0), as we already know.
For g(x) = -8x + x^2 + 7 the x-value of the vertex is at:
x = -(-8)/(2*1) = 4
Evaluating g(x) at x = 4 we get:
g(4) = -8*4 + 4*4 + 7 = -9
So the vertex is at (4, -9).
To go from (0, 0) to (4, -9) we need to move right 4 units and down 9 units, so the correct option is the third one.

Evaluate the function f(x) = -212-3x + 5 for the input value-3.
Answer:
f(-3)=-198
Step-by-step explanation:
Function: f(x) = -212-3x + 5
x=-3
First substitute -3 for x:
f(-3)=-212-3(-3)+5
Next multiply -3 by -3:
-3*-3=9
f(-3)=-212+9+5
-212+9=-203
f(-3)=-203+5
-203+5=-198

what is the solution to the equation below? sqrt 2-3x / sqrt 4x =2
The solution to the equation sqrt 2-3x / sqrt 4x = 2 is x = -2/3.
To solve the equation, we must first clear the denominators and simplify the equation. We can do this by multiplying both sides by sqrt(4x) and then squaring both sides. This gives us:
sqrt 2-3x = 4sqrt x
2 - 6x + 9x² = 16x
9x² - 22x + 2 = 0
Using the quadratic formula, we can find that x = (-b ± sqrt(b² - 4ac)) / 2a. Plugging in a = 9, b = -22, and c = 2, we get:
x = (-(-22) ± sqrt((-22)² - 4(9)(2))) / 2(9)
x = (22 ± sqrt(352)) / 18
x = (22 ± 4sqrt22) / 18
Simplifying this expression, we get:
x = (11 ± 2sqrt22) / 9
Therefore, the solution to the equation is x = -2/3.
To solve the equation sqrt 2-3x / sqrt 4x = 2, we must clear the denominators and simplify the equation. This involves multiplying both sides by sqrt(4x) and then squaring both sides.
After simplifying, we end up with a quadratic equation. Using the quadratic formula, we can find that the solutions are x = (11 ± 2sqrt22) / 9.
However, we must check that these solutions do not result in a division by zero, as the original equation involves square roots. It turns out that the only valid solution is x = -2/3.
Therefore, this is the solution to the equation.

At the end of the day of teaching the skill of cutting and sewing to make capes, Ms. Ironperson and Mr. Thoro decided to go to the Shawarma Mediterranean Grill. Ms. Ironperson ordered 3 chicken shawarma wraps and 2 orders of spiced potatoes for a total bill of $42.95. Mr. Thoro ordered 5 chicken shawarma wraps and 4 orders of spiced potatoes for a total bill of $74.91. What is the cost of a chicken shawarma wrap? What is the cost of one order of spiced potatoes? If x denotes the cost of a chicken shawarma wrap and y denotes the cost of an order of spiced potatoes, what are the equations needed to solve this problem?
Answer:
The cost of a chicken shawarma wrap = $10.99
The cost of an order of spiced potatoes=$4.99
Equations needed
3x+2y =42.95
5x + 4y=74.91
Step-by-step explanation:
x = the cost of a chicken shawarma wrap
y = the cost of an order of spiced potatoes
Ms. Ironperson
3x+2y =42.95
Mr. Thoro
5x + 4y=74.91
3x+2y =42.95 (1)
5x + 4y=74.91 (2)
Multiply (1) by 2
6x + 4y=85.9 (3)
5x + 4y=74.91. (2)
Subtract (2) from (3)
6x - 5x= 85.9 - 74.91
x=$10.99
Substitute the value of x into (1)
3x+2y =42.95 (1)
3(10.99) + 2y =42.95
32.97 + 2y = 42.95
2y = 42.95 - 32.97
2y=9.98
Divide both sides by 2
y=9.98/2
=4.99
y=$4.99
Therefore,
The cost of a chicken shawarma wrap = $10.99
The cost of an order of spiced potatoes=$4.99

a guy combined a 10oz substance containing 6% cottonseed with another substance containing 12% cottonseed to create a substance with 8% cottonseed. How many ounces of the 12% substance must he use?
By solving a linear equation for the concentration we will see that the guy needs to use 18 ounces.
How many ounces of the 12% substance must he use?We know that the guy used 10 ounces of 6% solution with x ounces of a 12% solution to make a 8% solution, then we can write the concentration equation:
0.06*12 + 0.12*x = (12 + x)*0.08
So we just need to solve a linear equation for x.
0.06*12 + 0.12*x = (12 + x)*0.08
0.06*12 + 0.12*x = 12*0.08 + x*0.08
0.12*x - 0.08*x = 12*0.08 - 0.06*12
0.04*x = 0.06*12
x = 0.06*12/0.04 = 18
Which means that the guy needs to use 18 ounces of the 12% substance.

A cube has edges measuring 7 inches each find the volume
The volume of the cube of 7 inches when calculated is 343 cubic inches
Calculating the volume of the cubeA cube is a three-dimensional solid figure that has six faces, each of which is a square.
All the edges of a cube are of equal length. In this case, each edge of the cube measures 7 inches.
To find the volume of a cube, we need to multiply the length, width, and height of the cube together.
Since all edges of the cube are of equal length, we can simply cube the length of one of the edges to find the volume.
Therefore, the volume of this cube is calculated by multiplying the length of one edge by itself three times:
Volume = 7 x 7 x 7 = 343 cubic inches.
So, the volume is 343 cubic inches.

can you factorise 3x²+5x+2
Answer:
Yes, (3x + 2)(x + 1).
Step-by-step explanation:
1. You're going to need to find two numbers that add to equal 5. The best option here is 2 and 3.
2. Separate the equation into groups. Right now, you have \(3x^2 + 5x + 2\). To separate into groups, you write \((3x^2 + 3x) + (2x + 2)\).
3. Now, from the first set of parenthesis, you can factor out 3x. This gets you \(3x(x + 1)\). The second set of parenthesis you can factor out the 2. This gets you \(2(x+1).\)
4. Now, you see that you have (3x + 2)(x + 1).

Fixed expenses 55,600
Net operating income $ 66,200

(Consider each case independently):
1. What would be the revised net operating income per month if the sales volume increases by 40 units?
2. What would be the revised net operating income per month if the sales volume decreases by 40 units?
3. What would be the revised net operating income per month if the sales volume is 7,700 units?
Last month when Holiday Creations, Incorporated, sold 37,000 units, total sales were $148,000, total variable expenses were $115,440, and fixed expenses were $35,800.
Required:
1. What is the company’s contribution margin (CM) ratio?
2. What is the estimated change in the company’s net operating income if it can increase sales volume by 500 units and total sales by $2,000? (Do not round intermediate calculations.)
1. Revised Net Operating Income = $66,760
2. Revised Net Operating Income =$64,640
3. Revised Net Operating Income =$52,
1. If the sales volume increases by 40 units:
So, New Sales = 8,700 units + 40 units = 8,740 units
and, New Contribution Margin =
= $14.00 x 8,740 units
= 122, 360
New Fixed Expenses remain the same at $55,600
Then, Revised Net Operating Income
= New Contribution Margin - New Fixed Expenses
= 122360 - 55600
= 66,760.
2. If the sales volume decreases by 40 units:
New Sales = 8,700 units - 40 units = 8,660 units
New Contribution Margin
= 14 x 8660
= 121,240
New Fixed Expenses remain the same at $55,600
Then, Revised Net Operating Income
= New Contribution Margin - New Fixed Expenses
= 65,640
3. If the sales volume is 7,700 units:
New Sales = 7,700 units
New Contribution Margin
= 14 x 7700
= 107,800
New Fixed Expenses remain the same at $55,600
Then, Revised Net Operating Income
= New Contribution Margin - New Fixed Expenses
= 52, 200
