All literal equations have how many variables ?

never [62]

Answer – Two or more variables (In other words, More than one variable)

In simple terms, literal equations are equations containing two or more variables; at least one independent variable and one dependent variable. In essence, all literal equations have more than one variable.

50 POINTS FIRST GOOD ANSWER GETS BRAINLIEST

Inessa [10]

Answer:

$f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.$

Step-by-step explanation:

We are given the function:

$f(x)=3+|2x-5|$

Remember that by the definition of absolute value:

$\displaystyle |x|= \left\{ \begin{array}{ll} x & \quad x \geq 0 \\ - x & \quad x < 0 \end{array} \right.$

Our absolute value is:

$|2x-5|$

First, we will find when it becomes 0. Set the equation equal to 0:

$2x-5=0$

Solve for <em>x: </em>

<em /> $x=5/2$ <em />

<em />

So, we can see that for all values greater than <em>x </em>= 5/2, 2x - 5 is positive.

For all values less than <em>x </em>= 5/2, 2x - 5 is negative.

Therefore (the positive case go above, and the negative case go below):

$|2x-5|= \left\{ \begin{array}{ll} 2x-5 & \quad x \geq 5/2 \\ -(2x-5) & \quad x < 5/2 \end{array} \right.$

Finally, we can add a three:

$f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 3+(2x-5) & \quad x \geq 5/2 \\ 3+(-(2x-5)) & \quad x < 5/2 \end{array} \right.$

Simplify if desired:

$f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.$

A. 3x-2y=-12<br> B.2x-3y=-12<br> C.3x+2y=12<br> D.3x+3y=-12

Nikolay [14]

Answer:

C

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = $\frac{0-6}{4-0}$ = $\frac{-6}{4}$ = - $\frac{3}{2}$ , then

y = - $\frac{3}{2}$ x + c

the line crosses the y- axis at (0, 6 ) ⇒ c = 6

y = - $\frac{3}{2}$ x + 6 ← equation in slope- intercept form

multiply through by 2 to clear the fraction

2y = - 3x + 12 ( add 3x to both sides )

3x + 2y = 12 ← equation in standard form
