Answer:
(Your answer choices were really confusing, so I just put the plain answer)
Step-by-step explanation:
To find the slope of a line with just two points, we can use the formula
. In this case,
. This is
. This reduces to 
Answer:
x = -7 and x = 4.
Step-by-step explanation:
f(x) = x^2 + 3x - 28
= (x + 7)(x - 4).
The reciprocal of f(x) can be written as
1 / (x + 7)(x - 4).
When the denominator is zero we have vertical asymptotes
so they are x = -7 and x = 4.
Answer:
x needs to be smaller or equal to -3
Step-by-step explanation:
-3x7 = -21
you get there by dividing -21 by 7
example smaller number: -4x7 = -28
54/72 gets reduced to 27/36 by the number 2 :)
