Answer:
see explanation
Step-by-step explanation:
The excluded values are any values of x that make the function undefined
Given

The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.
(x + 4)(x - 2)(x - 5) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 5 = 0 ⇒ x = 5
x = - 4, x = 2, x = 5 are the excluded values
Why not look up "standard deviation" yourself, to be sure? But yes, the std. dev. is the sqrt of the variance.
Magnetic power and then u can do like bold hehe
Answer:
2y=11 - 5x
Step-by-step explanation:
An equation that is parallel shares the same gradient thus
2y= -5x - 8
y = -5/2x- 4
gradient m = -5/2
substitute value of m and the co-ordinates into a new linear equation
y = mx + c
-9 = (-5/2)(8) + c
c = 20-9 = 11
thus y = -5/2x + 11
2y=11 - 5x
