Answer:

FORMULAS 

a (b + c) = ab + ac

(a + b)2 = a2 + 2ab + b2

(a − b)2 = a2 − 2ab + b2

(a + b)(a − b) = a2 − b2

Making Groups ( factorize four terms)

2x² - 2x + 5x - 5

= 2x (x - 1) + 5(x - 1)

= (x - 1) (2 x + 5)

Evaluation of algebraic expressions 

The process of replacing the variables in an expression with the numerical values and simplifying it is known as evaluating an algebraic expression. Following order of operation is used to evaluate an algebraic expression;

1. Perform the operations inside a parenthesis first

2. Then exponents

3. Then multiplication and division, from left to right

4. Then addition and subtraction, from left to right

Hope this will help you if you need more help about algebra free to ask i will try ! 

because algebra is big enough

For all integers n, if n2 is odd, then n is odd. Use a proof by contraposition, as in Lemma 1.1. Let n be an integer. Suppose th

Reil [10]

Let's assume that the statement "if n^2 is odd, then is odd" is false. That would mean "n^2 is odd" leads to "n is even"

Suppose n is even. That means n = 2k where k is any integer.

Square both sides

n = 2k
n^2 = (2k)^2
n^2 = 4k^2
n^2 = 2*(2k^2)

The expression 2(2k^2) is in the form 2m where m is an integer (m = 2k^2) which shows us that n^2 is also even.

So this contradicts the initial statement which forces n to be odd.

What is the equation in standard form of the line shown on the graph?

Andreyy89

well, let's check the graph, and use two points off of it..hmmmm it passes through (4, 0) and it also passes through (0, -4).

so, what would be the equation of a line that passes through those two points?

keeping in mind that

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{-4}) ~\hfill slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-4-0}{0-4}\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-0=1(x-4)\implies y=x-4 \\\\\\ -x+y=-4\implies \stackrel{\textit{standard form}}{x-y=4}\\\hspace{34em}$
