At first, it is important to know about function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
Graph of a function f(x) is the collection of points of the form (x, f(x))
The equation is y + 6 = x + 4
y = x + 4 - 6
y = x - 2

Triangle XYZ is shown on the coordinate plane below:
If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?
Answer:
Step-by-step explanation:
Triangle XYZ has been reflected across a line y = 1,
Therefore, line y = 1 will work like a mirror and all the distance of the points of the points from this line will be equal after the reflection about this line.
Distance of X from this line = 2 units
After reflection distance of X' from the line of reflection will be 2 units in opposite side.
Therefore, coordinates of X' will be (3, 3)

10 cubic feets volume is equivalent to 25.85 inches.
Answer:
Option B
Step-by-step explanation:
Volume of a cube is:
[tex]A = s^3[/tex]
s - side length
All sides are the same length in a cube.
We are given the information that the total volume of the cube is 10 cubic feet.
[tex]10=s^3\\\\\sqrt[3]{10}=\sqrt[3]{s^3}\\\\\boxed{2.154435... = s}[/tex]
2.154435... ≈ 2.15
The approximate height of the cube is 2.15 inches.
Since the height of the shelf is 24 inches tall, the cube should be able to fit.
2.15 < 24
Option B should be the correct answer.
Hope this helps.

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones, can be modeled by the polynomial 2x2 + 55x + 10. The cost, in dollars, of producing the cell phones can be modeled by 2x2 – 15x – 40. The variable x represents the number of cell phones sold.
What expression represents the profit, and what is the profit if 240 cell phones are sold?
40x – 30; $2,400
40x – 30; $9,570
70x + 50; $16, 850
70x + 50; $28,800
Answer:
Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.
Step-by-step explanation:
The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850
How to calculate profitRevenue, R = 2x² + 55x + 10Cost, C = 2x² – 15x – 40where,
x = number of cell phones sold.
Profit = Revenue - cost
= (2x² + 55x + 10) - (2x² – 15x – 40)
= 2x² + 55x + 10 - 2x² + 15x + 40
Profit = 70x + 50
If x = 240Profit = 70x + 50
= 70(240) + 50
= 16,800 + 50
= $16,850

Is a triangle with side lengths of 5, 10, and 15 a right triangle? Explain
Answer:
No, it is not a right triangle.
Step-by-step explanation:
Using the property of the right triangle, square root (5^2 + 10^2) = 5root(5), and it is not equal to 15, so it is not a right triangle.
Allison has a loyalty card good for a discount at her local hardware store. The item she wants to buy is priced at $36, before discount and tax. After the discount, and before tax, the price is $30.96. Find the percent discount.
Answer:
14%
Step-by-step explanation:
Original price of item = $36
Price after discount = $30.96
Percentage discount = x
To get the percent discount
x = 36 - 30.96/36
x = 5.06/36
x = 0.14
Percentage discount = 0.14 % 100
Percentage discount = 14%

Answer:
(x, y) ⇒ (x -5, y +3)
Step-by-step explanation:
Pick a point on the original polygon. The extreme left point (at (1, 0)) will do.
Locate the corresponding image point on ABCDE. (It is point B(-4, 3).) Using coordinates, or counting grid squares, determine what must be added to the original point to get the image point.
Here, that addition is 5 squares left and 3 squares up:
image - original = (-4, 3) -(1, 0) = (-5, 0)
So, the transformation rule adds -5 to each x-coordinate and 3 to each y-coordinate:
(x, y) ⇒ (x -5, y +3)

Alright,Alex let say we have factored a quadratic into two binomial, for example
[tex](5x + 3)(6x - 4)[/tex]
If we set both of those equal to zero
[tex](5x + 3)(6x + 4) = 0[/tex]
We can used the zero product property in this case to find the roots of the quadratic equation.
This means that
[tex]if \: ab = 0 \: then \: a = 0 \: and \: b = 0[/tex]
This means we set each binomal equal to zero to find it root.
[tex]5x + 3 = 0[/tex]
[tex]5x = - 3[/tex]
[tex]x = - \frac{3}{5} [/tex]
[tex]6x + 4 = 0[/tex]
[tex]6x = - 4[/tex]
[tex]x = - \frac{2}{3} [/tex]
So our roots are negative 3/5 and negative 2/3 using zero product property
