The decreasing linear relationship is shown in table 1. The correct option is A.

The linear relation is defined as the variation of the variables by a constant factor with the different values of variables x and y.

The given table is,

X    Y

4     10

7     17

10   18

13   22

The linear relation will be calculated as:-

y = kx

k = y / x

k = 10 / 4 = 2.5

k = 17 / 7 = 2.42

k = 18 / 10

k = 1.8

k = 22 / 13 = 1.69

The slope will be,

m = ( 17 - 10 ) / ( 7 - 4 ) = 7 / 3

Therefore, table 1 depicts the decreasing linear relationship. A is the correct answer.

the answer is all trapezoids have one pair of parallel sides.

to change the temperature from -13 on Saturday to -4 on Sunday, you would need to add 9 degrees ( -13 + 9 = -4 )

 so you need the equation that would also = 9

-4 + 13 = 9

-4 - (-13) = 9

-4 -13 = -17

4 +(-13)= -9

 there are 2 equations that equal the correct change in temperature, but since both temperatures are negative ( -13 & -4)

 the correct equation would also contain 2 negative numbers

 so correct equation should be: -4-(-13) =

Final answer:

To find out the number of marbles Ben has, we set up equations based on the information given, solve for Jerry's marbles (J), and then use that to solve for Ben's marbles (B). Ben has 172 marbles.

Explanation:

Let's denote the number of marbles Jerry has as J, and the number Ben has as B. According to the problem, Ben has one more marble than three times the number of marbles Jerry has, so we can write this relationship as B = 3J + 1. Together, Ben and Jerry have a total of 229 marbles, which gives us the equation B + J = 229.

Now, we can substitute the expression for B from the first equation into the second equation to solve for J:

Now that we know Jerry has 57 marbles, we can find out how many marbles Ben has:

Therefore, Ben has 172 marbles.

Answer:

  (D)  3x +6 ≤ 3

Step-by-step explanation:

Since there is a solid dot at x=-1, the inequality must include "≤", which eliminates the first two choices.

You can check x=-1 in each of the remaining choices to see which results in the "equal to" case.

Answer:

The cost to book dealer is $65

Step-by-step explanation:

Given : The price of an antique book is $91.

           The price is two - fifth more than the cost to book dealer.

To Find : Cost.

Solution :

Let the cost to book dealer be x

The price of an antique book is $91.

Two - fifth of the dealer cost  :  [tex]\frac{2}{5}x[/tex]

Since we are given that  price is two - fifth more than the cost to book dealer.

⇒[tex]x+\frac{2}{5}x=91[/tex]

⇒[tex]\frac{7}{5}x=91[/tex]

⇒[tex]x=\frac{91*5}{7}[/tex]

⇒[tex]x=\frac{455}{7}[/tex]

⇒[tex]x=65[/tex]

Hence , The cost to book dealer is $65

The values of x in both equations are 1/26 and 1/50, respectively

The equations are linear equations.

So, the variable can be calculated by simply dividing both sides by the coefficient

Using the above as a guide, we have the following computations:

Part A: (26)x = 1

Divide both sides by 26

x = 1/26

Part B: (50)x = 1

Divide both sides by 50

x = 1/50

Hence, the values of x in both equations are 1/26 and 1/50, respectively

Answer:

Step-by-step explanation:

Part A: If (26)x = 1, what is the value of x? Explain your answer. 

The value of x is 0. Anything to the 0 power = 1. So I had to figure out what times 6 would = 0. Anything times 0 = 0. Hence x = 0 because 6 x 0 = 0 and 2^0 =1.

Part B: If (50)x = 1, what are the possible values of x? Explain your answer.

X could be any number because anything times 0 = 0. In order for the answer to be 1, I had to figure out how to keep 5 to the 0 power. Since anything times 0 = 0, it doesn't matter what number x is, because anything times 0 =0. 

Answer: 10/3 or 3 1 /

Step-by-step explanation:

First ywould turn the 1 1/3 cups into an improper fraction. That makes the math a little easier. 1 1/3 = 4/3. You know that 4/3 cups makes two dozen cookies. So, if you take half of 4/3 which is 2/3 that is how many cups it takes to make one dozen. Then to find how many cups it would take to make 5 dozen just multiply 2/3 by 5 to get 10/3 or 3 1/3

In order to find out how many albums will fit in the box, divide the total height of the box by the thickness of one album. This resulted in a total of 64 albums.

The problem involves determining the number of record albums that can be stacked into a box with a height of 12 inches. Each album is 3/16 of an inch thick. To find the number of albums, you will need to divide the total height of the box, which is 12 inches, by the thickness of one album.

Here is the calculation: 12 ÷ (3/16) = 12 ÷ 0.1875 = 64.

Therefore, you can fit 64 albums in a 12-inch high box. Remember, this involves simple division and understanding of fractions and their decimal equivalents.
