Answer:
<h2>x = 4</h2>
Step-by-step explanation:

Multiply through by 4 to eliminate the fraction
That's

<u>Subtract x from each side</u>
That's

<u>Subtract 8 from each side</u>

<u>Divide both sides by 3</u>

We have the final answer as
<h3>x = 4</h3>

Step-by-step explanation:
Logarithm is basically the exponent - also called power - to which a base must be raised to produce a given number.
Mathematically, it can be displayed as:
is the logarithm of
to the base
, if
, in which case we write

Lets take the first example,

as

Therefore, 4 is the logarithm of 16 to base 2.
Lets take the second example,



- Logarithmic functions are basically inverse of exponents.
Here is how they are related to each other:
Logarithm → Exponent
→ 
- Logarithms are helpful in displaying large number.
By making 80=2x+20 by corresponding angles in parallel lines you find x=30 because 2(30)+20=80
Answer: x-intercept = (3,0); y-intercept = (0,7)
Step-by-step explanation:
-3y = 7x - 21
y = -7/3 x + 7 (divide both sides by -3)
y-intercept = (0,7) (y = mx + b; b is always y-intercept)
0= -7/3 x + 7 (plug in 0 for y to get x-intercept)
-7/3x = -7 (subtract 7 from both sides)
x = 3 (divide both sides by -7/3)
x-intercept = (3,0)
