The formula F=1.8C+32 can be used to convert temperature units. F is degrees Fahrenheit, and C is degrees Celsius.

stich3 [128]

Answer:

-40 °F = -40 °C

Step-by-step explanation:

The formula F = 1.8C + 32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius. Complete the equation you can solve to find that temperature and then use it to find the temperature. Use the variable C to represent the number of degrees Celsius where degrees Fahrenheit and degrees Celsius are the same. The equation is . The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is °C.

F = 1.8 C + 32 (1)

There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius

Then,

F = C (2)

Substitute (2) into (1)

F = 1.8 C + 32 (1)

C = 1.8C + 32

Subtract 1.8C from each side

C – 1.8 C = 32

-0.8C = 32

Divide both sides by -0.8

C = 32 / -0.8

C = -40

Substitute C = -40 into (1)

F = 1.8C + 32 (1)

F = 1.8(-40) + 32

F = -72 + 32

F = -40

Therefore,

The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is -40

That is,

-40 °F = -40 °C

how would you say "the function is positive from -9 to 3 over the x axis but -9 is not included" using interval notation

notka56 [123]

Answer:

The function would be positive in:

Step-by-step explanation:

A function is considered positive on the X-axis when the changed values in the function are greater than zero. f(x) > 0

And is considered negative when f(x) < 0.

In this case, the numbers that make the function positive are the numbers from -9 to 3, but not including -9.

This can be written as (-9, 3]

It means that -9 is not taken but any number greater than -9 is.

Adam has x x dimes and y y nickels. He has no less than 18 coins worth a maximum of $1.50 combined. Solve this system of inequal

Dvinal [7]

Answer:

The number of nickles is 6

The number of dims is 12 .

Step-by-step explanation:

Given as :

Sum of total number of dims and nickels coins = 18

The value of total combination = $1.50

Let The total number of dims = d

Let The total number of nickels = n

1 nickles = $0.05

1 dims = $0.1

<u>According to question</u>

Total number of dims and nickels coins = number of dims + number of nickels

Or, d + n = 18 .........1

And

$0.1 ×d + $0.05 ×n = $1.50

Or, 0.1 d + 0.05 n = 1.50 .........2

Now, Solving eq 1 an eq 2

0.1 × (d + n) - (0.1 d + 0.05 n) = 0.1 × 18 - 1.50

Or, (0.1 d - 0.1 d) + (0.1 n - 0.05 n) = 1.8 - 1.50

Or, 0 + 0.05 n = 0.3

Or, 0.05 n = 0.3

∴ n = $\dfrac{0.3}{0.05}$

i.e n = 6

So, The number of nickles = n = 6

Put the value of n int eq 1

∵ d + n = 18

Or, d = 18 - n

Or, d = 18 - 6

i.e d = 12

So, The number of dims = d = 12

Hence, The number of nickles is 6 and the number of dims is 12 . Answer
