because it makes more sense
You do 35 divide by 18 = 1.94 repeating
Answer:
5x +y = 34
Step-by-step explanation:
Since a point and slope are given, it is convenient to start with point-slope form, then rearrange the equation to put it into standard form.
For slope m through point (h, k), the point-slope form of the equation of a line is usually written ...
y -k = m(x -h)
For m=-5 and (h, k) = (6, 4), the equation is ...
y -4 = -5(x -6)
y -4 = -5x +30 . . . . . eliminate parentheses
__
Standard form looks like ...
ax + by = c
where a > 0 and GCD(a, b, c) = 1. Here's how we can get there.
5x +y -4 = 30 . . . . . . add 5x
5x +y = 34 . . . . . . . . . add 4 to get standard form.
Answer:
The answer is 9
Step-by-step explanation:
Given that a = √3 + √2 and b = √3 - √2 . To be more easier, we do it one by one :
First, a² :
(√3 + √2)(√3 + √2)
= 3 + √6 + √6 + 2
= 5 + 2√6
Second, ab :
(√3 + √2)(√3 - √2)
= 3 - √6 + √6 - 2
= 1
Third, b² :
(√3 - √2)(√3 - √2)
= 3 - √6 - √6 + 2
= 5 - 2√6
Then, evaluate a² - ab + b² :
5 + 2√6 - 1 + 5 - 2√6
= 9
