For each of the graphs below choose inequality that best represent the graph. explain your reasoning.
Sveta_85 [38]

The desired inequalities are given as follows:

A. A. x > x + 1. because solving it yields an inequality that is False for all real numbers x.

B. D. x < x + 1, because solving it yields an inequality that is True for all real numbers x.

<h3>Which inequality represents graph A?</h3>

For graph A, as nothing is plotted on the line, we have a inequality with no solution.

The successor of a number(number plus 1), will always be greater than the number, hence the inequality that has no solution is:

A. x > x + 1. because solving it yields an inequality that is False for all real numbers x.

<h3>Which inequality represents graph B?</h3>

For graph B, as the entire line is plotted, we have a inequality with all real values as solution.

From the same logic above, of the successor, the correct option is:

D. x < x + 1, because solving it yields an inequality that is True for all real numbers x.

Factorise x^2/4-y^2/4​
Nuetrik [128]

Answer:

\large\boxed{\left(\dfrac{x}{2}-\dfrac{y}{2}\right)\left(\dfrac{x}{2}+\dfrac{y}{2}\right)=\dfrac{x-y}{2}\cdot\dfrac{x+y}{2}}

Step-by-step explanation:

\dfrac{x^2}{4}-\dfrac{y^2}{4}=\dfrac{x^2}{2^2}-\dfrac{y^2}{2^2}\qquad\text{use}\ \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}\\\\=\left(\dfrac{x}{2}\right)^2-\left(\dfrac{y}{2}\right)^2\qquad\text{use}\ (a-b)(a+b)=a^2-b^2\\\\=\left(\dfrac{x}{2}-\dfrac{y}{2}\right)\left(\dfrac{x}{2}+\dfrac{y}{2}\right)=\dfrac{x-y}{2}\cdot\dfrac{x+y}{2}

Perform the indicated operation and write the answer in the form a + bi.<br> (3 +81) (4-3i)
kkurt [141]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \: 36 + 23 i

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: (3 + 8i)(4 - 3i)

\qquad \tt \rightarrow \: (3 \sdot 4)+ (3 \sdot - 3i) + (8i \sdot4) + (8i \sdot - 3i)

\qquad \tt \rightarrow \: 12 - 9i + 32i  - (24  {i}^{2} )

\qquad \tt \rightarrow \: 12 + 23i -( 24 \sdot - 1)

\qquad \tt \rightarrow \: 12 + 23i + 24

\qquad \tt \rightarrow \: 36 + 23i
