The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.
Answer:
45 is um 9x+xy-4y
Step-by-step explanation:
I did it it was a simplify type thing
Step-by-step explanation:
2 × 10⁸ - 7 × 10⁷
= 200,000,000 - 70,000,000
=130,000,000
= 1.3 × 10⁸
<h3>Given:</h3>
▪ 
First, rewrite the numerator in such a way that the coefficient 2.1 becomes 21:
Divide the coefficient:
Divide the base by subtracting the exponents of the base 10.
Hence, the quotient of the given expression has a coefficient of 3 and the exponent of the base 10 is -4.
