In order for the data in the table to represent a linear function with a rate of change of –8, what must be the value of m?

m = 2
m = 3
m = 19
m = 35

Answers

a rate of change of –8
so
27 - 8 = 19
19 - 8 = 11

answer

m = 19

Answer:

m= 19

Step-by-step explanation:

In a linear function the rate of change of y-variable respect x-variable must be constant. In mathematical terms:

Δy/Δx = constant

Given two points of the function: (x1, y1) and (x2, y2), Δy = (y2 -y1) and Δx = (x2 -x1).  So,

Δy/Δx = (11 -27)/(12-10) = -8

(m -27)/(11-10) = -8

(m -27) = -8*(11-10)

m = -8 + 27

m = 19

During a sale,Susan grody paid $155 for a clothes dryer.The price paid reflects a 75% discount off the original price. Determine what is the original price of the dryer.

Answers

I think the answer is 155x0.25=38.75

The original price of the dryer would be; 38.75 dollars.

How to calculate the unit price of something?

Unit means 'single entity, the fundamental constructing block. Usually, it is 1 in mathematics and science. Thus, the unit price of something is the price of 1 thing.

Given that Susan grody paid $155 for a clothes dryer.

The price paid by her reflects a 75% discount off the original price.

Required the original price of the dryer.

Thus,

100 - 75 = 25%

A bathtub that holds 32 gallons of water contains 12 gallons of water. begin filling it, and after 5 minutes the tub is filled. write a standard equation

Answers

Answer:

In standard equation format, the condition can be written as [tex]V=5x+12[/tex].

Step-by-step explanation:

The capacity of the bathtub is 32 gallons.

The water already in the tub is 12 gallon.

It takes 5 minutes for the tub to be filled.

Let x be the flow rate of water through tap, in gallon per minutes.

Now, the water filled in the tank in 5 minutes will be [tex]5x[/tex] gallons.

So, in equation, the given condition can be written as,

[tex]V=5x+12\\32=5x+12[/tex]

here V represents the volume of the bathtub.

Therefore, in standard equation format, the condition can be written as [tex]V=5x+12[/tex].

For more details, refer the link:

https://brainly.com/question/22527528?referrer=searchResults

Final answer:

The standard equation for the volume of water in the bathtub at time t is V(t) = 12 + 4t, indicating the tub starts with 12 gallons and fills at a rate of 4 gallons per minute.

Explanation:

To write a standard equation for filling a bathtub, we need to find the rate at which the tub fills. Since the tub starts with 12 gallons and ends up holding 32 gallons, it needs an additional 20 gallons to be filled. If it takes 5 minutes to fill these 20 gallons, then the fill rate is 20 gallons per 5 minutes.

The equation for the volume V of water in the tub at any given time t (in minutes) is:


V(t) = 12 + r × t

where r is the rate of filling the tub. We already calculated r to be 4 gallons per minute (20 gallons/5 minutes). Therefore, the equation becomes:


V(t) = 12 + 4t

This equation represents the amount of water in the bathtub at any given time t, assuming it starts with 12 gallons and fills at a rate of 4 gallons a minute.

Final answer:

To solve this system of equations using the elimination method, we multiply one or both equations so that the coefficients of either x or y are the same or additive inverses. Then, we subtract one equation from the other to eliminate one variable. Finally, we solve for the remaining variable by substituting the value of the other variable.

Explanation:

To solve the system of equations using the elimination method, we need to eliminate one variable by multiplying one or both equations so that the coefficients of either x or y are the same or additive inverses. In this case, we can multiply the first equation by 3 and the second equation by 2:



12x + 6y = 54

4x + 6y = 30



Next, we subtract the second equation from the first:



(12x + 6y) - (4x + 6y) = 54 - 30

8x = 24



Divide both sides by 8 to solve for x:



x = 3



To find the value of y, substitute the value of x into either of the original equations:



4(3) + 2y = 18

12 + 2y = 18

2y = 18 - 12

2y = 6

y = 6/2

y = 3

Line segment JL is an altitude in triangle JKM. Which statement explains whether JKM is a right triangle? Round measures to the nearest tenth.

A) JKM is a right triangle because KM = 15.3.
B) JKM is a right triangle because KM = 18.2.
C) JKM is not a right triangle because KM ≠ 15.3.
D) JKM is not a right triangle because KM ≠ 18.2.

Answers

Answer:

C. JKM is not a right triangle because KM ≠ 15.3.

Step-by-step explanation:

We can see from our diagram that triangle JKM is divided into right triangles JLM and JLK.  

In order to triangle JKM be a right triangle [tex]KM^{2}=JK^{2}+JM^{2}[/tex].

We will find length of side KM using our right triangles JLM and JLK as [tex]KM=KL+LM[/tex].  

Using Pythagorean theorem in triangle JLM we will get,

[tex]LM=\sqrt{JM^{2}-JL^{2}}[/tex]

[tex]LM=\sqrt{8^{2}-5^{2}}[/tex]

[tex]LM=\sqrt{64-25}[/tex]

[tex]LM=\sqrt{39}=6.244997998\approx 6.24[/tex]

Now let us find length of side KL.

[tex]KL=\sqrt{JK^{2}-JL^{2}}[/tex]  

[tex]KL=\sqrt{13^{2}-5^{2}}[/tex]

[tex]KL=\sqrt{169-25}[/tex]

[tex]KL=\sqrt{144}=12[/tex]

Now let us find length of KM by adding lengths of KL and LM.

[tex]KM=12+6.24=18.24[/tex]

Now let us find whether JKM is right triangle or not using Pythagorean theorem.

[tex]KM^{2}=JK^{2}+JM^{2}[/tex]  

[tex]18.24^{2}=13^{2}+8^{2}[/tex]

[tex]18.24^{2}=169+64[/tex]

[tex]18.24^{2}=233[/tex]

Upon taking square root of both sides of equation we will get,

[tex]18.24\neq 15.264337522473748[/tex]

[tex]18.2\neq 15.3[/tex]  

We have seen that KM equals 18.2 and in order to JKM be a right triangle KM must be equal to 15.3, therefore, JKM is not a right triangle and option C is the correct choice.

A retiree invests $8,000 in a savings plan that pays 7% per year. What will the account balance be at the end of the first year?

Answers

Final answer:

To calculate the account balance at the end of the first year for an investment of $8,000 at 7% per year, the formula for simple interest is used. After applying the formula, the final account balance is determined to be $8,560.

Explanation:

The retiree invests $8,000 in a savings plan that pays 7% per year. To find out what the account balance will be at the end of the first year, we can use the formula for simple interest because it is only for one year. The formula is:

Final amount = Principal amount (1 + (Interest rate * Time))

Let's calculate:

Principal amount (P) = $8,000Interest rate (r) = 7% or 0.07Time (t) = 1 year

Now, substituting the values into the formula:

Final amount = $8,000 (1 + (0.07 * 1))

Final amount = $8,000 (1 + 0.07)

Final amount = $8,000 (1.07)

Final amount = $8,560

So, the account balance at the end of the first year will be $8,560.

Twelve less than negative nine times a number is equal to 8 minus 4 times the number find the number

Answers

Final answer:

The number that satisfies the original equation is -4.

Explanation:

A student's question involves finding a number that satisfies the equation: 'Twelve less than negative nine times a number is equal to 8 minus 4 times the number'.

To solve this, we set up the equation -9x - 12 = 8 - 4x.

Solving for 'x' involves simple algebraic steps.

First, add 9x to both sides to get the variable terms on one side:

-9x - 12 + 9x = 8 - 4x + 9x-12 = 8 + 5x

Next, subtract 8 from both sides to isolate the variable term:

-12 - 8 = 5x-20 = 5x

Finally, divide both sides by 5 to find 'x':

-20 / 5 = 5x / 5-4 = x

The number that satisfies the original equation is -4.

Answers

If we leftover 1 toothbrush, we will have:
56 tubes of toothpaste, 112 packets of floss and 84 toothbrushes.
The greatest common factor:
GCF ( 56, 112, 84 ) = 28
56 : 28 = 2, 112 : 28 = 4, 84 : 28 = 3
Answer:
The greatest number of identical dental care bags is 28.
In every bag will be 2 tubes of toothpaste, 4 packets of floss and 3 toothbrushes. One toothbrush will be leftover.
 
Greatest number of identical dental care bags is equal to the L.C.M. of 56, 112 & 85.

56 = 2 x 2 x 2 x 7
112 = 2 x 2 x 2 x 2 x 7
85 = 5 x 17

L.C.M. (56, 112, 85) = 2 x 2 x 2 x 2 x 5 x 7 x 17
= 560 x 17
= 9520

Therefore, 9520 is the correct answer.

if the inequality has the same number on both sides for the answer is that ok?

Answers

If the problem was |6y+6| < 0, then you would be able to say 0 < 6y+6 < 0 (because of the template below)

Template:
if |x| < k, then -k < x < k

----------------------------------------------------------------------------------

However, the inequality sign is not a "less than" sign. Instead its a "greater than" sign. 

So instead you should use this template

if |x| > k then x > k or x < -k

So if 
|6y+6| > 0
then
6y+6 > 0 or 6y+6 < 0

Solve each inequality for y
6y+6 > 0
6y+6-6 > 0-6 ... subtract 6 from both sides
6y > -6
6y/6 > -6/6 ... divide both sides by 6
y > -1

Do the same for the other inequality
6y+6 < 0
6y+6-6 < -6
6y < -6
6y/6 < -6/6
y < -1

---------------------------------------------------------------------------------

So overall, the two solutions are y > -1 or y < -1

The keyword "or" is important. You can only choose one inequality or the other, but not both.
