Answer:

Advantages of representing a function as an equation instead of graph :

No chance of misinterpretation of the data as making graph involves more data as compared to data needed to represent function as an equation.
Drawing graphs may be inconvenient in case you need to plot fraction and decimal functions.

Disadvantages of representing a function as an equation instead of graph :

Visualization is easy in case of graph. Many factors such as maximum, minimum can be easily seen with the help of graph as compared to that of equation of the function.
With the help of curve of the graph, we can identify the nature of the function much easily than by the equation of the function.

Sarah spends of her monthly take-home pay on rent, food, and clothing. If she earns $1,830 in take-home pay each month, how much

frosja888 [35]

Sarah spendings

We have that Sarah spends 2/3 of $1,830 in rent food and clothing

In order to find the money she spends, we just have to divide $1,830 in 3 and multiply the result by 2:

$\begin{gathered} \frac{1830}{3}=610 \\ 610\cdot2=1220 \end{gathered}$ <h2>Answer - D. $1,220</h2>

Krista's mom has told her she needs to make the pen ½ the size that she had planned (5 feet long by 4 ½ feet wide). What will th

saw5 [17]

Answer:

1. area of new pen = 11 $\frac{1}{4}$ $ft^{2}$

2. i. 5 feet by 2 $\frac{1}{4}$ feet

ii. 2 ½ feet by 4 ½ feet

Step-by-step explanation:

The size of the pen as planned = 5 ft long by 4 ½ ft wide

Area of the pen = length x width

= 5 x 4 ½

= 5 x $\frac{9}{2}$

Area of the pen = $\frac{45}{2}$

= 22 ½ $ft^{2}$

But, Krista has to make the pen ½ the size of planned. So that;

area of new pen = ½ x 22 ½

= ½ x $\frac{45}{2}$

= $\frac{45}{4}$

= 11 $\frac{1}{4}$

area of new pen = 11 $\frac{1}{4}$ $ft^{2}$

The area of the new pen would be 11 $\frac{1}{4}$ $ft^{2}$ .

The possible values she could use are:

i. 5 feet by 2 $\frac{1}{4}$ feet

ii. 2 ½ feet by 4 ½ feet

Factor-3/4 out of 3/2x-9/4y

S_A_V [24]

For this case we must factor $- \frac {3} {4}$ of the following expression:

$\frac {3} {2} x- \frac {9} {4}y$

By law of signs of multiplication it is fulfilled that:

$- * - = +\\- * + = -$

So we have to:

$- \frac {3} {4} * (- 2) = + \frac {6} {4} = + \frac {3} {2}\\- \frac {3} {4} * 3 = - \frac {9} {4}$

Thus, by factoring we have:

$- \frac {3} {4} (- 2x + 3y)$

Answer:

$- \frac {3} {4} (- 2x + 3y)$
