If the temperature dropped to -16 degrees what is the absolute value?
Answer:
32.63 F
Step-by-step explanation:
The function:

represents sound travels s at feet per second, where t is the temperature at Fahrenheit degrees.
We know that sound traveled at a rate of 1121 ft/sec. To find the temperature we need to replace with s value and isolate t for the above function.






Answer:
<em>The values are a=6, b=8</em>
Step-by-step explanation:
<u>System of Equations</u>
We are given the system of equations:
ax - by = 4
bx - ay = 10
And it's known the solutions are: x=2, y=1.
Plugging in the solutions:
2a - b = 4 [1]
2b - a = 10 [2]
Now we have to solve the system above. Multiply [1] by 2:
4a - 2b = 8
Now we add with [2]:
3a = 18
a = 18/3 = 6
a = 6
From [2]:
2b - 6 = 10
2b = 16
b = 16/2 = 8
b = 8
The values are a=6, b=8
