Answer:

$f = -\frac{15}{4}$

Step-by-step explanation:

$f + \frac{1}{4} = -\frac{7}{2}$

-1/4 -1/4 Subtract 1/4 from each side of the equation to isolate f.

$f = -\frac{7}{2} -\frac{1}{4}$ in order to subtract these fractions, we need

to make both fractions have the same denominator.

2 x 2 = 4, so we can just multiply the top and bottom

by 2 to get -14/4. Now we can subtract the fractions.

$f = -\frac{14}{4} -\frac{1}{4}$ Since the denominators are the same now, ignore

the bottom and focus on subtracting the numerators.

-14 - 1 = -15.

$f = -\frac{15}{4}$ This is the final answer.

Answer:

f = -15/4

Step-by-step explanation:

f+1/4= -7/2

Subtract 1/4 from each side

f+1/4-1/4= -7/2-1/4

f = -7/2 -1/4

Get a common denominator of 4

f = -7/2*/2/2 - 1/4

f = -14/4-1/4

f = -15/4

Karen purchased the DVD

9966 [12]

Answer:

Percent markdown = 14%

Step-by-step explanation:

Given:

Original price of DVD player = $175.90

Markdown price of DVD player =$153.77

To find percent markdown.

Amount of mark down $=\textrm{Original price - Markdown price}=\$175.90-\$153.77=\$22.13$

Percent markdown $=\frac{Amount\ of\ markdown}{Markdown\ price}\times100=\frac{22.13}{153.77}\times 100=14.39\%\approx 14\%$

Write the equation of the line in fully simplified slope-intercept form. y intercept = -2 (GIVE EXPLANATION)

nekit [7.7K]

Answer:

See Below:

Step-by-step explanation:

So, first of all. to find the equation of the line, the equation has to be in $y=mx+b$ form. In this for the following are:

$m$ is the slope of the line
$b$ is the y intercept

Solving

So, first of all, to find the equation of the line, we can get two points from the line, you can pick any points you want, but for this case, I will be using (0,-2) and (-2,0).

To solve for the slope, we can use rise over run to find the equation.

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

Upon inserting our points into the equation, we get a slope of -1.

$\frac{0-(-2)}{-2-0}=\frac{2}{-2}=-1$

Creating The Equation

To create the equation in $y=mx+b$ form, we need to know what the intercept and the slope are, for which we solved above. We can now put in the things we found to get our final equation.

$y=-1x-2$
