Answer:
c. x² + 2x -5 = 0
Step-by-step explanation:
Given expression;
= 
Unknown:
The quadratic equation equivalent to this expression:
Solution:
The common denominator here is 3x;
So, multiply both sides by 3x
x 3x = 
3x
5 x 3 = (x + 2)x
15 = x² + 2x
So;
x² + 2x - 15
The quadratic expression is x² + 2x - 15
Answer:

Step-by-step explanation:
x+15=6x-65
x+80=6x
80=5x
16=x
hope this helps :P
Just talk about the differences and similarities between exponential and logarithmic functions. Talk about how the domain and range is affected by the different functions.
2y-7x=-9
4x+6=y
2(4x+6)-7x=-9
8x-7x=-12-9
x=-21
y=4(-21)+6
y=-84+6
y=-78
