Answer) A
Explanation) 6:7 is equal to 36:42 because you can multiply both 6 and 7 by 6 to get 36:42.
In this exercise we have assumption:
x-4>0
x>4
from this we know domain : x∈(4,+infinity)
range y∈R
Answer:
To calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. * i didnt know what to put so i put this*
X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
Its arithmetic because it adds 1o each time
