For this case we must resolve the following expression:
We have to:

The base change rule can be used if a and b are greater than 1 and are not equal to x.
We substitute the values in the base change formula, using 

Answer:
-4
Option A
Answer:
10 units
Step-by-step explanation:

Okay so x represents the amount of tickets sold. So first, you’d add the $40 + $70 which equals $110. So x = $110.
Now we have to solve for y. Same thing but with different numbers. $200 + $260 = $460.
The answer is (110,460)
x. y.
Answer:
y=sqrt((x+a)/-2b))
F=(5/9)C+32
Can't read the rest
Step-by-step explanation:
-2by^2=x+a
y^2=(x+a)/-2b
y=sqrt((x+a)/-2b))
F-32=(5/9)C
F=(5/9)C+32 (The actual Fahrenheit-Celcius formula)
