Question 4 (Multiple Choice Worth 1 points) The graph of a system of parallel lines will have no solutions. Always Sometimes Never
Always
CAN I ASK YOU ONE MORE ??
go ahead
The graph of a system of equations with the same slope will have no solutions. Always Sometimes Never
always
TY
AND ONE MORE 2x + 3y = 3 3x – 2y = 11 What is the solution to the system? (–3, 3) (–1, –7) (1, –4) (3, –1)
multiply first eqn by 3 and second by -2 6x + 9y = 9 -6x + 4y = -22 now add the two 13y = -13 y = -13/13 = -1 substitute y = -1 in first eqn 2x + 3(-1) = 3 2x - 3 = 3 2x = 6 x = 6/2 = 3 so solution is (3, -1)
both say "will have no solution"
"never mind" lol, I see now, good answer Harkirat
THANK YOU THATS WHAT I HAD JUST HAD TO MAKE SURE CAN YOU HELP ME WITH JUST ONE MROE QUESTION THEN ILL STOP PBOTHER YOU
Go ahead, I will try.
It is no bother.
Part 1: Provide a system of TWO equations in slope-intercept form, with only one solution. Using complete sentences, explain why this system has one solution. Part 2: Provide a system of TWO equations in slope-intercept form with no solutions. Using complete sentences, explain why this system has no solutions. Part 3: Provide a system of TWO equations in slope-intercept form with infinitely many solutions. Using complete sentences, explain why this system has infinitely many solutions. ** ALL I NEEED IS EXAMPLES
O.K. I'm on it.
OK THANK YOU
I GOT A ANSWER TO IT I WANT YOU TO TELL ME IS IT RIGHT
for Part 1, system with one solution, When you graph out a system of equations ( let say there is only 2). The intercept of the 2 lines, the point where they intercept is the solution. So if they intercept at only one point there is only one solution. EXP., y=x+2 y=2x+4.. For part 2, system with no solution, for 2 lines to not intersect, is when both lines are parallel. if both lines are parallel they will never intersect even when stretched to infinity. EXP.y=x+2 y=x+4 for part 3, system with infinite solution, it is when both lines intersect at every point, which means to say they are the same line An example will be x+y=2 2x+2y=4 Both are the same line when simplified. EXP y=x+1 2y=2x+2
Pt. 1:y=3x+1 y=4x-1 Pt. 2. y=-2x +9 y= -2x + 2 pt. 3 y = x -1 y= (2) .5x +(-1)
Normally when an equation is in slope intercept form, the coefficient of y is a 1. So for Pt. 3, it is the same equation (an identity) and has infinite solutions.
if you dont mind i have more quest i reallly appericate your help
