The lines intersect at (-1.8,-4.4)
Answer:
8
Step-by-step explanation:
Two different approaches:
<u>Method 1</u>
Apply radical rule √(ab) = √a√b to simplify the radicals:
√98 = √(49 x 2) = √49√2 = 7√2
√50 = √(25 x 2) = √25√2 = 5√2
Therefore, (√98 - √50)² = (7√2 - 5√2)²
= (2√2)²
= 4 x 2
= 8
<u>Method 2</u>
Use the perfect square formula: (a - b)² = a² - 2ab + b²
where a = √98 and b = √50
So (√98 - √50)² = (√98)² - 2√98√50 + (√50)²
= 98 - 2√98√50 + 50
= 148 - 2√98√50
Apply radical rule √(ab) = √a√b to simplify radicals:
√98 = √(49 x 2) = √49√2 = 7√2
√50 = √(25 x 2) = √25√2 = 5√2
Therefore, 148 - 2√98√50 = 148 - (2 × 7√2 × 5√2)
= 148 - 140
= 8

Answer:
See Explanation
Step-by-step explanation:
Let us briefly explain the terms
- Variable: This is the letter in the expression
- Coefficient: This is the number beside the letter above
- Constant: This is a number without any variable attached.
Let us take our expression with two terms to be: 3x+5
Coefficient =3
Variable =x
Constant =5
The word phrase of the expression is:
5 added to the product of 3 and a number.
The quantity of distance measures in miles depends on the quantity of time measured in hours. is your best choice.
The quantity of time is an independent variable, as it continues to go no matter how much you travel, and so it is the independent.
The quantity of distance depends on your speed and time, and because it depends on these two factors, it is the dependent.
hope this helps
