Solve: -6 (-2)÷4(-3)
Katen [24]

Answer:

-9

Step-by-step explanation:

Simplify the following:

-6×(-2)/4 (-3)

-6×(-2)/4 (-3) = (-6 (-2) (-3))/4:

(-6 (-2) (-3))/4

The gcd of -2 and 4 is 2, so (-6 (-2) (-3))/4 = (-6 (2 (-1)) (-3))/(2×2) = 2/2×(-6 (-1) (-3))/2 = (-6 (-1) (-3))/2:

(-6-1 (-3))/2

(-6)/2 = (2 (-3))/2 = -3:

--3 (-3)

-3 (-1) = 3:

3 (-3)

3 (-3) = -9:

Answer: -9

Does the table represent a function, -3, 6, -2,9, 0,4, -2,5
Ronch [10]

Answer:

No.  There are two solutions to the point x=-2:  9 and 5.

Step-by-step explanation:

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, for the same x position, then the graph is not a function.
