All you have to do to solve this equation is plug the equation you have that already is manipulated for y. Y=2X+3 and substitute it into the equation for y in the first equation, 2x-y=7. So it becomes 2x-(2x+3)=7. By distributing the - sign into the brackets we get 2x-2x-3=7. 0-3=7. -3 does not equal 7. Thus I would think the answer is no solution.
Logan wants to know how many skateboards have defective parts. he inspects 20,000 skateboards and keeps track of the number of defects per board. use his probability distribution table to find the expected value for defects on a skateboard.
Brainliest ! which of the coordinates are not of th vertices of the feasible region for the system of inequalities yโค4,,xโค5,x+y> 6 a(2,4) b(0,6) c(5,4) d(5,1)
What is the distance between a and b? round your answer to the nearest tenth. a coordinate plane is shown. point a is located at negative 1, 5, and point b is located at 4, 1. a line segment connects the two points.
