Answer:
-5a-15/4
______
6
Step-by-step explanation:
Answer:
6) No, two angles are not equal
7) yes, two angles are equal
Yes, you can see by subtracting 32 from the bottom sides and seeing that the correspondent for 20 degrees celcius is double that of the correspondent for 10 degrees celcius
To solve this problem you must apply the proccedure shown below:
1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.
2. You have the equation of the line has the following form:

Where
is the slope and
is the y-intercept.
3. Then, you have that the slope of the function
is:

Therefore, the answer is: 
Step-by-step explanation:

Given equaiton is in the form of ax^2 +bx+c=0
we apply quadratic formula to solve for x

a= 1 b = -12 and c= 59



Divide the 12 and square root terms by 2

so
and
