For this case we have to:
x: Represents the unknown number
y: Represents the exponent of base 10
So, considering a system of equations we have:
From the first equation we have:
Substituting in the second equation:
We choose the positive value:
So, the number is 0.4.
So:
Thus, the exponent is 5.
Answer:
Yara use 0.4 and
Answer:
Option D
Step-by-step explanation:
By the property of intersecting chords,
If two chords are intersecting at a point inside a circle, product of lengths of the line segments on each chord is equal.
DI × EI = HI × GI
12 × EI = 8 × 6
EI =
EI = 4
Therefore, Option D is the correct option.
When solving this equation you get x = -3.
To solve this, simply follow the order of operations for solving.
----> start by dividing both sides by 5
-----> Now you can transform the front side of the equation to use negative exponents.
Since both x and -3 are the powers of x, we can eliminate the 7 and just make the exponents equal.
-3 = x
