Factor the equation. [tex]x^2-21x-72[/tex]
Answer:
(x - 24)(x + 3)
Step-by-step explanation:
Given
x² - 21x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 21)
The factors are - 24 and + 3, since
- 24 × + 3 = - 72 and - 24 + 3 = - 21 , then
x² - 21x - 72 = (x - 24)(x + 3) ← in factored form

Write the equation in standard form for the circle that has a diameter with endpoints (- 1, 12) and (- 1, 8)
Answer:
The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]
Step-by-step explanation:
The distance from (-1, 12) to (-1, 8) = 4 = diameter of the circle. So, 2 = radius
The center of the circle is at (-1, 10)
The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]

someone help i found the slope already.
Answer:
s(x)
Step-by-step explanation:
s(x) is a linear function, so the average rate of change is its slope.
Its slope is 3.
You are correct.
To find the average rate of change of polynomial function t(x) from -2 to 2, find the values of t(x) at x = -2 and at x = 2.
average rate of change = [t(2) - t(-2)]/[2 - (-2)]
t(x) = 0.1(x^3 - x^2 + 2)
t(-2) = 0.1[(-2)^3 - (-2)^2 + 2)]
t(-2) = 0.1(-8 - 4 + 2)
t(-2) = -1
t(2) = 0.1[(2)^3 - (2)^2 + 2)]
t(2) = 0.1(8 - 4 + 2)
t(2) = 0.6
average rate of change = [t(2) - t(-2)]/[2 - (-2)]
average rate of change = [0.6 - (-1)]/4
average rate of change = 1.6/4
average rate of change = 0.4
average rate of change for s(x) = 3
average rate of change for s(x) = 0.4
Answer: s(x)

What is BODMAS rule ?
The BODMAS rule states that an expression with more than one operators need to be solved from left to right in order of BODMAS, where B = Brackets, O = Orders, D = Division, M = Multiplication, A = Addition, S = Subtraction.
What is the required value ?The given expression is 16+4-(5×2)+2
First we have to do multiplication in bracket,
= 16+4-10+2
= 20-10+2
= 10+2
= 12
The value = 12

Subtract -2x^2+4x-1−2x 2 +4x−1minus, 2, x, squared, plus, 4, x, minus, 1 from 6x^2+3x-96x 2 +3x−9
Answer:
-86x^2 -2x - 8
Step-by-step explanation:
The solution is:
6x²+2x²+3x-4x-9+1 becomes 8x²- x -8.
What is Subtraction?Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.
Here, we have,
Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).
To subtract -2x^2+4x-1 from 6x^2+3x-9,
that is
6x^2+3x-9 - (-2x^2+4x-1).
This can be written as
6x²+3x-9 - (-2x²+4x-1)
Now, opening the bracket, we will get
6x²+3x-9 +2x²-4x+1
Then, collecting like terms, we get
6x²+2x²+3x-4x-9+1
6x²+2x² = 8x²
3x-4x = -x
-9+1 = -8
∴6x²+2x²+3x-4x-9+1 becomes 8x²-x -8
The answer is 8x²-x -8.
