Can someone check my answer please HELP!

Let price of one scarf be $x
Price of the other is 3 more than $x
Therefore price of the other scarf =$x +3
The total price she paid = $25.00
That is, x+x+3=25
2x+3=25
2x=25-3
2x=22
x=22/2
x=11
The price of one scarf is $11 and the price of the other is 11+3=$14
The price of the expensive scarf =$14.

Answer:

Part A: 15

Part B:

Point slope form: $y-400=15(x-5)$

Slope intercept form: $y =15x+325$

Standard Form: $15x-y+325=0$

Part C: $g(x) =15x+325$

Part D: 505

Step-by-step explanation:

We are given the following

x g(x)

5 $400

10 $475

We can see that these are two points on the line.

i.e. (5, 400) and (10, 475)

OR

$x_1 = 5\\x_2 = 10\\y_1 = 400\\y_2 = 475$

<u>Part A: </u>Slope of the function:

$m=\dfrac{y_2-y_1}{x_2-x_1} \\\Rightarrow m = \dfrac{475-400}{10-5}\\\Rightarrow m = \dfrac{75}{5} = 15$

So, slope of the line = 15

<em>It has a positive slope and the function will be increasing with the increasing value of 'x'.</em>

<em></em>

<u>Part B:</u>

Point slope form of a line is given as:

$y-y_1=m(x-x_1)$

Putting $(x_1, y_1)\ as\ (5, 400)$ :

$y-400=15(x-5)$

Slope intercept form:

$y=mx+c$ where c is the intercept.

$y =15x+c$

Putting (x,y) as (5, 400) to find c:

$400=15\times5+c\\\Rightarrow c = 325$

So, the equation in slope intercept form:

$y =15x+325$

Standard form of line:

$Ax+By+C=0$

Rewriting the slope intercept form:

$15x-y+325=0$

<u>Part C:</u>

Using the function notation, putting y = g(x) in slope intercept form:

$g(x) =15x+325$

<u>Part D:</u>

Balance after 12 days = ?

i.e. g(x) = ? at x = 12

Putting x = 12 in $g(x) =15x+325$

$g(12) =15\times 12+325\\\Rightarrow g(12)=505$

A patient is to take 4 2/3 tablespoons of medicine per day in 4 equally divided doses. How much medicine is to be taken in each

anygoal [31]

Answer:

1 1/6

Step-by-step explanation:

4 2/3 ÷ 4

Convert the mixed number into an improper fraction:

4 2/3 = 14/3

14/3 ÷ 4

14/3 ÷ 4/1

Use cdf (copy dot flip)

14/3 × 1/4

14 × 1 / 3 × 4

14/12

Convert improper fraction into a mixed number:

14/12 = 1 2/12

1 1/6
