Solve system of equations by elimination. Show all your steps. - 3x + 5y = -11
3x + 7y = -1

x and y = (2,-1)

Step-by-step explanation:

3x + 5y = -11

3x = -1 - 7y

-(-1 - 7y) + 5y = -11

y = -1

3x=-1-7x(-1)

x = 2

(x,y) = (2,-1)

-3x2+5x(-1) = -11

3x2+7x (-1) = -1

-11 = -11

-1 = -1

solution

x and y = (2,-1)

the answer is b i just did that

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
