Answer:
(4,-3)
Step-by-step explanation:
If the line passes through a point, the coordinates of the point will verify the equation of the line.
So, let's see if each of the coordinates verifies the equation 3x - 2y = 6
A. (4,-3) means x=4 and y = -3
so 3x - 2y becomes 3(4) - 2(-3) = 12 - -6 = 12 + 6 = 18
B. (4/3, -1) means x = 4/3 and y = -1
so 3x - 2y becomes 3(4/3) - 2(-1) = 4 - -2 = 4 + 2 = 6
C. (-2,-6) means x= -2 and y = -6
so 3x - 2y becomes 3(-2) - 2(-6) = -6 - -12 = -6 + 12 = 6
Verified that the line passes by the last two points but not the first one.
So, 672 miles divided by 56 miles per hour = 12 hours
The point (4,7) is the only one that can be plugged into the equation and work. in this case when 4 is plugged in as X & Y is plugged in at 7 we get that 7=7, which is a true statement.
Answer:
A. - 4
Step-by-step explanation:
f(4) = 4(4) - 20 = 16 - 20 = - 4
Answer: 12
Step-by-step explanation:
I will assume those are coordinates.
The distance between 2 points is given by √ (x2 − x1)^2 + (y2 − y1)^2.
Replacing the values, we get √ (5 − 5)^2 + (6 − -6)^2 = √0+144 = 12
