Suppose we want to choose 2 colors, without replacement, from the 4 colors red, blue, green, and purple. How many ways can this be done, if the order of the choices is relevant? How many ways can this be done, if the order of the choices is not relevant?

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

because that’s us why

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
