Answer:

Step-by-step explanation:

This question is incomplete; here is the complete question.

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.

If it continues to fall at this rate, what will the temperature be:

In 2 hours ............. In 5 hours .............. In half an hour......................

If the current temperature of the mountain is b°C and it is falling at a constant rate of 3°C per hour.

Then after 'x' hours, temperature on the top of the mountain will be represented by the function,

T(x) = 0 - 3x

Therefore, temperature after 2 hours = -3(2) = -6°C

Temperature after 5 hours = -3(5) = -15°C

Temperature after half an hour = -3(\frac{1}{2})

                                                    = -1.5°C

Y=3x-5 y=6x-8 show all steps and write the solution
m_a_m_a [10]

Step 1: Set the two equations equal to each other and solve for x.

3x -5 = 6x - 8

3x + (-5+5) = 6x -8 + 5

(3x - 6x) = (6x - 6x) - 3

-3x/-3  = -3/-3

x = 1

Step 2: To solve for y take one of the given equation of your choice (for the purpose of this explanation I will only do y = 3x - 5) and replace x with 1, then solve for y

y = 3(1) - 5

y = 3 - 5

y = -2

(1,-2)

Check:

-2 = 3(1) - 5 ---> - 2 = -2

-2 = 6(1) - 8 ---> -2 = -2

Hope this helped!

Please help me !!!!!!!!!!!!!!!!

Answer: x=-10, y=13

Step-by-step explanation:

-3x+2y=56\\-5x-2y=24

+2y-2y = 0, eliminating y is much easier. So -3x-5x = -8x and 56+24 = 80

-8x=80\\x=-10

Substitute x in any equations but only 1 equation (Don't substitute in both equations.)

For me, I'd substitute x in -3x+2y=50

-3(-10)+2y=56\\30+2y=56\\2y=56-30\\2y=26\\y=13

So the answer is x = -10, y = 13
