Explain what the equation 4h = -14 represents.
-4. Temperature dropping per hour
h , Number of hours
-14. Temperature after 'h' hours
What value of h makes the equation true?
What value of h makes the equation true

value of h makes the equation true is -3.5

Step-by-step explanation:

=> 4h = -14

multiply both side by h

=>

=>

divide -14 by 4

÷> h = - 3.5

the equation -4h=-14 represents that after h hours the temperature of the outside environment is -14°C

It means that it takes 3.5 hours for the temperature of the outside environment to be -14°C

h ≥ 3.5

Step-by-step explanation:

Since the temperature after h hours is -4h, the equation -4h=-14 represents that after h hours the temperature of the outside environment is -14°C. To calculate the value of h, we divide both sides of the equation by -4.

Since -4h=-14

Dividing through by -4:

-4h / -4 = -14 / -4

h = 3.5

It means that it takes 3.5 hours for the temperature of the outside environment to be -14°C

The inequality -4h ≥ -14

Solving by dividing through by -4:

h ≥ 3.5

This means that at 3.5 hours the temperature of the outside environment must be greater than or equal to-14°C

the equation -4h=-14 represents that after h hours the temperature of the outside environment is -14°C

It means that it takes 3.5 hours for the temperature of the outside environment to be -14°C

h ≥ 3.5

Step-by-step explanation:

Since the temperature after h hours is -4h, the equation -4h=-14 represents that after h hours the temperature of the outside environment is -14°C. To calculate the value of h, we divide both sides of the equation by -4.

Since -4h=-14

Dividing through by -4:

-4h / -4 = -14 / -4

h = 3.5

It means that it takes 3.5 hours for the temperature of the outside environment to be -14°C

The inequality -4h ≥ -14

Solving by dividing through by -4:

h ≥ 3.5

This means that at 3.5 hours the temperature of the outside environment must be greater than or equal to-14°C

⇒ Temperature dropping per hour

⇒  Number of hours.

⇒ Temperature after 'h' hours

Step-by-step explanation:

Given:

Current temperature = 0 degrees

Temperature dropping per hour = -4 degrees.

Temperature after h hours =

We need to explain what the equation represents.

Solution:

Now we know that;

Temperature after h hours =

Now we know that;

Current temperature is 0 degrees and temperature is decreasing at a rate of -4 degrees per hour so if we multiply -4 from h which number of hours it will show the temperature after h hours.

So we can say that;

-14 will be the temperature after 'h' hours in equation  .

where;

⇒ Temperature dropping per hour

⇒  Number of hours.

⇒ Temperature after 'h' hours

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

The total nom of  code that can be used is equal to 5+3 = 8

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53
