Equivalent equations are equations that have the same value
The equation in logarithmic form is 
<h3>How to rewrite the equation</h3>
The expression is given as:

Take the logarithm of both sides

Apply the power rule of logarithm

Divide both sides by log(10)

Apply change of base rule

Divide both sides by 2

Rewrite as:

Hence, the equation in logarithmic form is

The diagonals intersect perpendicularly, two consecutive angled are supplementary, and that opposite angles are equal
You need to write it out such as number 8 would be 10x10x10x10 so for every number on top you multiply the number by itself
Step-by-step explanation:
slope= -1/2
y intercept= 2
y=mx+b
m is the slope and b is the y intercept.
Answer:
<h2>
10. C. (2, -1)</h2><h2>
11. B. (-2, -4)</h2>
Step-by-step explanation:
10.

The y values cancel out if you add the equations
5x = 10
x = 2
plug in x
2 - 2y = 4
-2y = 2
y=-1
Answer: C. (2, -1)
11.

In order to get terms to cancel out, multiply the top by 3 and bottom by 2

The y values cancel out if you add the equations
10x = -20
x = -2
plug in x
6(-2) - 2y = -4
-12 - 2y = -4
-2y = 8
y = -4
Answer: B. (-2, -4)
