(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
(a + b) (a – b) = a2 – b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x – b) = x2 + (a – b)x – ab
(x – a)(x + b) = x2 + (b – a)x – ab
(x – a)(x – b) = x2 – (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3 = a3 – b3 – 3ab(a – b)
(x + y + z) 2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y – z) 2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
(x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
(x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
x2 + y2 = 1212 [(x + y)2 + (x – y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3 = (x + y) (x2 – xy + y2)
x3 – y3 = (x – y) (x2 + xy + y2)
x2 + y2 + z2 -xy – yz – zx = 1212 [(x-y)2 + (y-z)2 + (z-x)2]

Michelle ordered 200 T-shirts to sell at the school carnival. She paid $2.80 per shirt, plus 5% of the total order for shipping. When she sells each T-shirt at the carnival, she adds 150% markup to the total price she paid for the shirt (including the cost of shipping). What is the selling price of each T-shirt? help i only have 10 points but plz help
Answer: 4.18$ or 4.19$ per shirt (I’m not entirely sure my answer is correct but do what you must with this info)
Step-by-step explanation: 200 times 2.80 is 560,
5% of 560 is 588,
150% of 588 is 882,
and then 882 divided by 200 is 4.18 (or 4.19)

Step-by-step explanation:
Answer:
1st Question is: 80%
2nd Question is: Option 'D'
Step-by-step explanation:
Both make a matter of 80%, the first one is because 4/5 in radical form is 80/100, The second answer is because 462 + 378 = 840, 840 simplified with 1,050 makes 4/5 = 80/100 or 80%

Which is the graph of f (x) = 3 (two-thirds)^x?
On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 6) and goes through (1, 4).
On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 6) and goes through (1, 2).
On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 3) and goes through (1, 1).
On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 3) and goes through (1, 2).
Answer:
Its D. On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 3) and goes through (1, 2).
Step-by-step explanation:
The graph of the function f(x) = 3^{(2/3)x} is an exponentially growing function.
What are some function transformations?Suppose we have a function f(x).
f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).
f(x ± c) = Horizontal left/right shift by c units (x - + c, y).
(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).
f(bx) = Horizontal compression b > 0, horizontal stretch for b < 0. (bx , y).
f(-x) = Reflection over the y-axis, (-x, y).
-f(x) = Reflection over x-axis, (x, -y).
The graph of the function f(x) = 3^{(2/3)x} is an exponentially growing function and has a y-intercept at (0, 1).
The function grows from the second quadrant to the first quadrant in an exponential manner as illustrated in the attached graph.

Use the converse of the Pythagorean theorem to decide whether ΔABC is a right triangle by answering the questions.
1. Use the Pythagorean theorem to find AD. Show your work.
2. Find AC. Show your work.
3. Is ΔABC a right triangle? Explain.
Answer:
1. Use the Pythagorean theorem to find AD. Show your work.
AD=9
Side BD=12, and side AB=15. We know that side AB is the hypotenuse, so AD^2+144=225
225-144=81, so side AD=9
2. Find AC. Show your work.
AC=25
To find AC, we can add AD and DC
9+16=25
3. Is ΔABC a right triangle? Explain.
ABC is a right triangle because AB^2+BC^2=AC^2

Click to show whether each equation represents a linear or nonlinear function.
Answer:
[tex]y = x^2 + 1[/tex] -- Nonlinear
[tex]y = x^1 + 2[/tex] -- Linear
[tex]y = x[/tex] --- Linear
[tex]y = 5(x + 2)[/tex] --- Linear
[tex]y = x(x)[/tex] --- Nonlinear
Step-by-step explanation:
Required
Categorize each function as linear or nonlinear
First, it should be noted that a linear function has the form [tex]y = mx + b[/tex].
So, the following question will be solved based on the above form
(a):
[tex]y = x^2 + 1[/tex]
This can not be expressed as [tex]y = mx + b[/tex]
Hence, it is a nonlinear function
(b):
[tex]y = x^1 + 2[/tex]
This can be further expressed as:
[tex]y = x + 2[/tex]
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(c):
[tex]y = x[/tex]
This can be further expressed as:
[tex]y = x + 0[/tex]
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(d):
[tex]y = 5(x + 2)[/tex]
This can be further expressed as:
[tex]y = 5x + 10[/tex] -- by opening the bracket
This has the same form as [tex]y = mx + b[/tex].
Hence, it is a linear function.
(e):
[tex]y = x(x)[/tex]
This can be further expressed as:
[tex]y = x^2[/tex] --- by opening the bracket
This can not be expressed as [tex]y = mx + b[/tex]
Hence, it is a nonlinear function
