Craig likes to collect vinyl records. Last year he had 10 records in his collection.Now he has 12 records.What is the percent increase of his collection

Answer:

-5/2

Step-by-step explanation:

5x+2y=6

First, put the equation in slope-intercept form

y = mx+b where m is the slope and b is the y intercept

Subtract 5x from each side

5x-5x+2y=-5x+6

2y = -5x+6

Divide each side by 2

2y/2 = -5/2x +6/2

y = -5/2 x +3

The slope is -5/2x

Lines that are parallel have the same slope

Answer:

j = 1

Step-by-step explanation:

-2.15+1.8+7.45 = 2.1j + 5j

7.1 = 7.1j

7.1/7.1 = j

Answer:

You can use 48 and 24

Step-by-step explanation:

You can figure out 48 by simply multiplying 6 times 8. You can figure out the 24 by noticing that 24 is divisible by both 6 and 8. 6 x 4 =24, and 8 x 3=24. I hope this helps!

Answer:

The numbers we could use for the denominators is 48  and 24.

Answer:

-38 + x = -21

Step-by-step explanation:

Since we don't know the number that -38 is being added to, we can suplement it in the equation with x.

Answer:

[tex] let \:x \in (A\cap B)'\\\Rightarrow x \notin (A\cap B) \\\Rightarrow x \notin A \:or\: x\notin B\\ \Rightarrow x \in A' \:or \:x \in B'\\\Rightarrow x \in A' \cup B'\\\therefore (A ∩ B)' = A' ∪ B' [/tex]

It is proved that , A Intersection B complement is equal to the union of the complements of the sets A and B i.e., (A ∩ B)' = A' ∪ B'.

What is a set ?

Sets are represented as a collection of well-defined objects or elements.

It is given that A , B , C , X are sets with A , B and C are subsets of X.

Let's assume X be an element of A intersection B complement. or (A ∩ B)'.

i.e.,

X ∈ (A ∩ B)'

Also , we can say that :

X ∉ ( A ∩ B)

This implies :

X ∉ A or X ∉ B

or we can also say that :

X ∈ A' or X ∈ B'

or

X ∈ A' ∪ B'

So , we can conclude that :

(A ∩ B)' = A' ∪ B'

or A Intersection B complement is equal to the union of the complements of the sets A and B.

Therefore , it is proved that , A Intersection B complement is equal to the union of the complements of the sets A and B i.e., (A ∩ B)' = A' ∪ B'.

Answer:

  (b)  -3

Step-by-step explanation:

The "initial value" is the constant in the equation. It is the value that remains when the x-term is removed. It is the result of evaluating the equation when x=0.

  y = -4(0) -3 . . . . substitute x=0

  y = 0 -3

  y = -3 . . . . the "initial value"

Step-by-step explanation:

[tex]2x - 10 + 4x + 16 = 180 \\ \\ 4x - 2x + 16 + 10 = 180 \\ \\ 2x = 180 - 26 \\ \\ 2x = 154 \\ \\ x = \frac{154}{2} \\ \\ x = 77[/tex]

Answer:

From the above attachment we can conclude that,

[tex](2x - 10)° + (4x + 16)° = 180° \\ 2x - 10 + 4x + 16 = 180 \\ 2x + 4x - 10 + 16 = 180 \\ 6x + 6 = 180 \\ 6x = 180 - 6 \\ 6x = 174 \\x = \frac{174}{6} \\ \boxed{x = 29}[/tex]

Therefore, the value of x is 29

Answer:

y =  2x - 1

Step-by-step explanation:

To find out the equation of the line, you will always need the following information in order to determine the linear equation in slope-intercept form, y = mx + b:

1. 2 sets of ordered pairs (x, y)

2. Slope (m)

3. Y-intercept (b)

First, we need to choose 2 points from the graph to solve for the slope:

Let (x1, y1) = (0, -1)

(x2, y2) = (3, 5)

Substitute these values into the following slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{5 - (-1)}{3 - 0} = \frac{5 + 1}{3} = \frac{6}{3} = 2[/tex]

Therefore, the slope (m) = 2.

Next, we need the y-intercept, (b). The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The y-coordinate of the point (0, -1) is the y-intercept.  Hence, the y-intercept (b) = -1.

Given our slope, m = 2, and the y-intercept (b) = -1, the linear equation is:

y = 2x - 1

Answer:

[x] =-15

Answer:

y = 12/7

Step-by-step explanation:

Slope = (change in Y) / (change in x)

-1/7 = (y - 2) / (3 - 1)

-1/7 = (y - 2)/2

Cross multiply:  -1(2) = 7(y - 2)

                             -2 = 7y -14

                        -2 + 14 = 7y

                                12  = 7y

                               12/7 = y

Let's find y

Answer:

  Yes, Yolanda bought enough

Step-by-step explanation:

a. Read and understand the question, including what is given and what is asked for. Here, we have ...

  Given: mixed nuts $6.75 per pound, $21.60 spent on mixed nuts; dried fruit $4.25 per pound, $11.90 spent on dried fruit.

  Find: is the total weight of purchased mixed nuts and dried fruit at least 6 pounds?

__

b. Select appropriate relations to create a path from what is given to what is asked for. Here, we have ...

  weight = cost/(cost per pound)

  total weight = weight of mixed nuts + weight of dried fruit

__

c. Use the relations with the given information to come to a conclusion that will answer the question.

  weight of mixed nuts = $21.60/($6.75/lb) = 3.2 lb

  weight of dried fruit = $11.90/($4.25/lb) = 2.8 lb

  total weight = (3.2 lb) +(2.8 lb) = 6.0 lb

Yolanda wanted to buy a total of 6 pounds for the party, and she bought 6 pounds. Yolanda bought enough for the party.

Answer:

$13,300

Step-by-step explanation:

$30,400 in to the ratio of 4:5:7

First lets add 4, 5, and 7:

4 + 5 + 7 = 16

Now divide 30,400 by 16 to find 1 share:

30,400/16 = 1900

Since the largest share is 7, we multiply 1900 by 7, since 1900 is equivalent of 1 share

1900 x 7 = 13300

We have that, how long it will take for Liu to catch Mariel is mathematically given as

t=3.076s

From the question we are told

Mariel and Liu are running a long-distance race. Mariel runs at a rate of 5.4 m/s, and Liu runs at a rate of 7.6 m/s. If Mariel has a 20 m head start, how long will it take for Liu to catch Mariel?

Generally the equation for the Average speed is  mathematically given as
