What are the solutions to the following system of equations? Select the correct answer below. y = x^2 − 4x + 3 2x + y = 6

ELEN [110]

2x+y=6

y=6-2x and y=x^2-4x+3

The solution occurs when they are equal so we can say y=y which is:

x^2-4x+3=6-2x add 2x to both sides

x^2-2x+3=6 subtract 6 from both sides

x^2-2x-3=0 factor

(x+1)(x-3)=0

So x=-1 and 3, using y=6-2x we find the corresponding y values...

y(-1)=6--2=8, y(3)=6-6=0 so the two solutions are the points:

(-1,8) and (3,0)

Which of the following are geometric series?

Temka [501]

Answer:

-256 +64 - 16 + 4 - 1

Step-by-step explanation:

A series is the summation of all the terms in a sequence.

So it is only the last three options that qualify to be a series.

The series 2 +5 + 8 + 11 + 14 + 17 has no common ratio. It is not geometric.

The series 1+1+2+3+5+ 8 +13 +21 also has no common ratio. It is not geometric.

The series -256 +64 - 16 + 4 - 1 has a common ratio of

$r=\frac{64}{-256}=-\frac{1}{4}$

There the only series that is geometric is.

-256 +64 - 16 + 4 - 1
