Answer: Option 3 = 4

Step-by-step explanation: f(x) = 6 - 2x

f(0) = 6 - 2(0) Range = 6

f(2) = 6 - 2(2) Range = 2

f(4) = 6 - 2(4) Range = -2

f(6) = 6 - 2(6) Range = -6

f(8) = 6 - 2(8) Range = -10

The only one that doesn't belong is 4 option 3.

You're welcome!!

Which is the graph of y = _0.4x? A. B. C. D.

cestrela7 [59]

Y = -0.4x

1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °

With all that information you can identify the graph, given that you didn't include the options.

the linear equation y=2x represents the cost y of x pounds of pears. which order pair lies on the graph of the equation? A. (2,4

Vladimir [108]

Answer:

A. (2, 4)

Step-by-step explanation:

The ordered pairs represent (x, y). Since you have y =2x, this is the same as ...

(x, 2x)

That is, the second number in the pair needs to be twice the first number in the pair. Since you know your times tables, you know that this is not the case for (1, 0), (10, 5) or (4, 12). Those values of x would give (1, 2), (10, 20), (4, 8).

It is the case that you have (x, 2x) for (2, 4).

The point (2, 4) lies on the graph of y = 2x.
