Answer:
top right graph
Step-by-step explanation:
because on every side of 0 the values are the same
We have this equation:
First, combine both logarithms using the multiplication property and simplify the expression.
![\log[x(x + 99)] = 2](https://tex.z-dn.net/?f=%5Clog%5Bx%28x%20%2B%2099%29%5D%20%3D%202)
![\log[ {x}^{2} + 99x ] = 2](https://tex.z-dn.net/?f=%5Clog%5B%20%7Bx%7D%5E%7B2%7D%20%2B%2099x%20%5D%20%3D%202)
Now, use the definition of logarithm to transform the equation.
Finally, use the quadratic formula to solve the equation.
With this, we can say that the solution set is:
We cannot choose x = -100 as a solution because we cannot have a negative logarithm. The only solution is x = 1.
Types of averages, they all give a general idea of the amount

Step-by-step explanation:
Answer: Y = -7X-2
Step-by-step explanation:
if there are two co-ordinates (x1,y1) and (x2,y2).
If the line is passing through these co-ordinates
Then Slopw of the line = (y2-y1)/(x2-x1)
We have one co-ordinate (-1,5) let it be (X1,Y1)
Let second co-ordinate be (X,Y)
Slope = -7 = (Y-5) / (X-(-1))
-7 = (Y-5)/(X+1)
Y-5 = -7 (x+1)
Y-5 = -7x-7
ADDING 5 ON BOTH SIDES OF THE EQUATION
Y-5+5 = -7X-7+5
Y = -7x-2
