Which of the following systems of equations has the solution (4, -1)?

3x - y = 0 and 4x + 3y = 26,

3x - 2y = 14 and 2x + 2y = 6,

-2x + 4y = 6 and -3x + 6y = 8,

4x + 9y = 1 and 4x + 6y = -2

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1

Parabolas y=−2x^2 and y=2x^2+k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.

Solve for b. ab + c= d b= a + old ob=allc-ch b= (d-c/a
