(- 1 + √3)/2
rationalise the denominator by multiplying the numerator/denominator by the conjugate of the denominator.
the conjugate of 1 + √3 is 1 - √3
(1 - √3)/(1 + √3)(1 - √3) = (1 - √3)/( 1² - (√3)²) = (1 - √3)/(1 - 3) = (1 - √3)/(- 2)
multiply numerator/denominator by (- 1)
=(-1 +√3)/2
Answer:
(n-1)2.1
Step-by-step explanation:
Since it already gives you a vaariable <u>n</u>, -->
P (n-1) -->
COnvert 110% to 2.1 / decimal
--> multiply
(n-1)2.1
Hope this helps!
Answer:
D) y = -1/3x - 7
Step-by-step explanation:
This graph has a negative slope, so immediately you can eliminate A.
Let's find the slope first. One point is (0,-7) and the other can be (-3,-6).
(-6+7)/(-3-0) = 1/(-3) = -1/3
Because the slope is -1/3, you can eliminate C.
Let's look at the y-intercept next. When x = 0, y = -7.
