Someone help me please

Mathematics
1 answer:
Studentka2010 [4]3 years ago
4 0

Step-by-step explanation:

The slope of the line passing through two points is given by,

\frac{y2 - y1}{x2 - x1}

13)

\frac{(0 - y)}{(0 - 2)}  =  (\frac{ - 3}{2} )

\frac{ - y}{ - 2}  =  \frac{ - 3}{2}

y =  - 3

option D

14)

\frac{ ( - 3 - y)}{(1 + 5)}  =  \frac{ - 1}{6}

\frac{ - 3 - y}{6}  =  \frac{ - 1}{6}

- 3 - y =  - 1

- y =  - 1 + 3 = 2

y =  - 2

option C

15)

\frac{(y - 4)}{( - 5 + 1)}  =  \frac{1}{4}

\frac{y - 4}{ - 4}  =  \frac{1}{4}

- y + 4 = 1

- y = 1 - 4 =  - 3

y = 3

option B

16)

\frac{(y + 3)}{( - 4 - 3)}  =  \frac{ - 3}{7}

- (y + 3) =  - 3

y = 3 - 3 = 0

option C

Explain the difference between a rate and a unit rate.
Anna35 [415]

Answer:

Step-by-step explanation:

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

An artist plans to sell $300 of prints online each week. This month, she is within $22 of her goal.
monitta

The minimum and maximum amounts that the artist received for her products are 278 and 322

<h3>Part A: Define a variable and write an absolute value equation to represent the scenario.</h3>

Let the number of prints remaining be x.

The given parameters are:

Total = 300

Amount = 22 within her goal

So, we have the following absolute value equation

|x - 300| = 22

<h3>Part B: Solve the equation, showing all steps.</h3>

In (a), we have:

|x - 300| = 22

Remove the absolute bracket

x - 300 = 22 and x - 300 = -22

Add 300 to both sides

x = 322 and x = 278

<h3>Part C: What are the minimum and maximum amounts that the artist received for her products?</h3>

The minimum and maximum amounts that the artist received for her products are 278 and 322

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. n^2-4n/3
ololo11 [35]

Answer:

(n- 2/3)²

Step-by-step explanation:

  • <em>Perfect square trinomial is: </em><em>a²+2ab+b²= (a+b)²</em>

We have:

  • n² - 4n/3

It can be put as:

  • n² -2×n×2/3

Here we consider n = a and -2/3 = b, then

  • b²= (-2/3)²= 4/9

Now we add 4/9 to a given binomial to make it perfect square:

  • n² - 2×n×3/2 + 4/9= (n- 2/3)²

So, added 4/9 and got a perfect square (n- 2/3)²

What is the length of the dotted line in the diagram below? Leave your answer in simplest radical form.
Pachacha [2.7K]

Answer:

\sqrt{93}

Step-by-step explanation:

8^2+5^2=c^2

64+25=c^2

89=c^2

c=\sqrt{89} <-- this is the length of the rectangle at the bottom

2^2+(\sqrt{89})^2=c^2

4+89=c^2

c=\sqrt{93}  <-- length of dotted line (diagonal)
