What is the best way to solve a literal equation?

Kobotan [32]

Answer:

To solve a literal equation means to express one variable with respect to the other variables in the equation.

Step-by-step explanation:

Determine which variable you need to isolate. Isolating a variable means getting the variable on one side of an equation by itself.

Use algebra to solve for the desired variable. Use inverse operations to cancel variables on one side of the equation and move them to the other side. 3.

Keep the equation balanced. Whatever you do to one side of the equation, you must also do to the other side

Pie

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

$(0, -4)\\(1,0)$

We found the slope:

$m = \frac {y2-y1} {x2-x1}\\m = \frac {0 - (- 4)} {1-0} = \frac {4} {1} = 4$

So, the equation is of the form:

$y = 4x + b$

We substitute a point to find "b":

$-4 = 4 (0) + b\\-4 = b$

Finally, the equation is:

$y = 4x-4$

<h2>Answer:</h2>

<h3>1) $\frac{1}{2}$ </h3><h3>3) $\frac{1}{6}$ </h3><h3>5) $\frac{2}{3}$ </h3><h3 /><h2>Step-by-Step Explanation:</h2><h3 />

1.<em> </em>Find the probability of rolling less than a four.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Outcomes lower than four</u> = 1, 2, 3

Then to answer it you need the probability in the form of a fraction.

$\frac{3}{6}$ simplifies into $\frac{1}{2}$

2. Find the probability of rolling an even prime number.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Prime Numbers Through 1-6</u> = 2, 3, 5

<u>Even Prime numbers Through 1-6</u> = 2

So the probability in the form of a fraction.

3. Find the probability of rolling factors of 20.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Factors of 20 Through 1-6</u> = 1, 2, 4, 5

So probabilty in the form of a fraction.

$\frac{4}{6}$ simplifies into $\frac{2}{3}$
