the equation of the circle with center at (4 , -1) is
Solve them both simultaneously:
A line drawn through A(4,-1) parallel to the line 3x-4y+1=0. Find the coordinates of the two points on this line which are at a distance of 5 units from A.
Okay, but call out if you need help. Sorry for the typo.
never mind, i understand it
I think 3) is wrong, could you express it in slope intercept?
I am still unsure about 2) and 3)
Anyways, i have a new problem:
2) Find B-A if the graph of Ax + By = 7 passes through (2,1) and is parallel to the graph of 2x - 7y = 3
3)The "perpendicular bisector" of the line segment is the line that passes through the midpoint of and is perpendicular to .
The equation of the perpendicular bisector of the line segment joining the points (1,2) and (-5,12) is y=mx+b. Find m + b.
:cool::DYou are correct
I have a large truck and my neighbor has four identical small trucks. My truck can carry at least 800 pounds more than each of her trucks, but no more than one-third what all four of her trucks combined can carry. Knowing only these facts, what is the largest number of pounds that I can be assured of being able to carry in my truck?
