Answer: 65
Step-by-step explanation:
Let
x-------> the number of hours
y------> the temperature in degrees Fahrenheit
we know that
For 
For 
The domain of the function is the interval----------> ![[0,30]](https://tex.z-dn.net/?f=%5B0%2C30%5D)
The range of the function is the interval----------> ![[-10,30]](https://tex.z-dn.net/?f=%5B-10%2C30%5D)
therefore
<u>the answer is</u>
The domain is all real numbers 0 through 30
Answer:
52
Step-by-step explanation:
given that the number is a
The expression for Ten less than 5 times the value of a number is given by
5a - 10
10 times the quantity of 12 more than one-fourth of the number.
a/4 is one-fourth of number
12 more than one-fourth of the number
a/4 + 12
expression for 10 times the quantity of 12 more than one-fourth of the number. is given by
10(a/4 + 12) = 10a/4 + 12*10 = 2.5a + 120
Given that the above two expression are equal
equating them we have
5a - 10 = 2.5a + 120
adding 10 both sides
=>5a - 10+ 10 = 2.5a + 120 + 10
=> 5a = 2.5a + 130
subtracting 2.5a from both sides
=> 5a - 2.5a = 2.5a + 130 - 2.5a
=> 2.5a = 130
dividing both side by 2.5
=> a = 130/2.5 = 52
Thus, value of a is 52
3n^2+7n-6n-14+4n^2+6n= 7n^2+7n-14
Hope that helps and best of wishes!
