Based on the temperature change and the amount of time it did so, the average change in temperature per hour is -3.5°F.

The average change in temperature per hour can be found by:

= Temperature change / Number of hours

Solving would give:

= -23.8 / 6.8

= -3.5°F

We can therefore conclude that in every hour of this cold day, the temperature changed by an average of -3.5°F.

Answer:

Step-by-step explanation:

f(x) = x^3 - 3x^2 - 28x + 60

x(x^2-3x-28)+60

Factor the inside of the parenthesis

Multiples of 28: (1X28),(2X14),(4X7). 7-4=3, 7 & 4 is the correct multiple.

x(x-7)(x+3)+60

Roots: 0,7,-3,6

Also you can plug your function into Desmos and see where it crosses the x-axis.

Step-by-step explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k = 34

k = 34-14

k = 20

__________

[tex] \: [/tex]

f(x) = x² - 5x + k

f(7) = 34

Soo :

f(7) = 34

(7)² - 5(7) + k = 34

49 - 35 + k = 34

14 + k = 34

k = 34 - 14

k = 20✔

Answer:

Rs 25000

Step-by-step explanation:

Saves 40%

Spends 60%

Spending 60% = 15000

If 60% = 15000

Then divide it by 6 to get 10%

10% = 15000 ÷ 6

10% = 2500

100% = 25000

Answer:

1.5 sec by meters

Step-by-step explanation:

90 meters/60 sec=1.5

Darrel walks at a unit rate of 1.5 m/sec.

Speed is defined as the rate of change of position in unit time.

Mathematically,

Speed = Distance/Time

Now it is given that,

Distance in walk by Darrell = 90 meters

Time taken by Darell to walk 90 meters = 60 seconds

Therefore Speed i.e unit rate of walk is given as,

Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters

⇒ Unit rate of walk = 90/60 m/sec

⇒ Unit rate of walk = 3/2 m/sec

⇒ Unit rate of walk = 1.5 m/sec

Thus, Darrel walk at a unit rate of 1.5 m/sec.

Answer:

x ≥ - 1

Step-by-step explanation:

10x + 5 ≥ 2x - 3 ( subtract 2x from both sides )

8x + 5 ≥ - 3 ( subtract 5 from both sides )

8x ≥ - 8 ( divide both sides by 8 )

x ≥ - 1

Step-by-step explanation:

Answer:

y=6x-506

Step-by-step explanation:

Start by finding the slope.

Let your x-axis be temperature and you y-axis be chirps per minute.

This leaves you with your two points to find slope.

The first point would be (100,94) and your second point would be (103,112).

From here we can do the standard slope equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex].

[tex]\frac{112-94}{103-100}[/tex]=[tex]\frac{18}{3}[/tex]

[tex]\frac{18}{3}[/tex] Is your slope for the line which can be simplified to 6.

Next find your y-intercept. This can be found by moving around your

y=mx+b equation.

y-mx=b

Pick a point to substitute into the equation. Ill use (103, 112).

[tex]112-6(103)=b[/tex]

[tex]112-618=b[/tex]

[tex]-506=b[/tex]

[tex]b=-506[/tex]

Knowing slope and the y-intercept we can write the slope intercept equation

y=6x-506

Answer:     x  < - 5

Step-by-step explanation:

6-3(x+2) > 15         [substract six from both sides]      

  -3(x+2) > 15 - 6   [divide both sides by -3; flip greater than sign to less than]

         x + 2 < - 3    [subtract two from both sides]

To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.

Answer:

2 2/5.

Step-by-step explanation:

Answer:

5t - 18

Step-by-step explanation:

STEP 1: Simplify 8/5

equation at end-                                                                                                           8 (7 - 3t) -  (5 • ((0 -  (— • t)) +  5)) 5          

STEP 2:          2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  5  as the denominator :

      5     5 • 5

   5 =  —  =  —————

        1       5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

\2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-8t + 5 • 5     25 - 8t

———————————  =  ———————

EQUATION AT END:  (25 - 8t)

 (7 - 3t) -  (5 • —————————)

                      5    

STEP 3:  (7 - 3t) -  (25 - 8t)

a || b will be the correct label for the parallel line so option (A) will be correct.

Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.

Parallel lines are those lines in which slopes are the same and the distance between them remains constant.

Given the two lines a and b as parallel.

If we want to show any two lines as parallel then we use |the | sign in between them.

Now in the given figure, A B C D are points on lines a and b so they will not be used to show parallel lines.

Answer:

75% of 60 = 45

Step-by-step explanation:

In order to find the answer to this question you need to divide the percentage of the number by one-hundred and then divide that number by the number the number you are trying to find the percentage of.

60/x=100/75

(60/x)*x=(100/75)*x        

60=1.33333333333*x      

(1.33333333333) to get x

60/1.33333333333=x

45=x

x=45

75% of 60 = 45
