Graph the solution to the inequality 4x + 5y < 20. Be sure to show the x- and y-intercepts of you line clearly on the graph.
Use your cursor to draw on the image below.
Finding two points (the x and y intercepts) you can graph any line or inequality.
Hint: remember, let x = 0 and solve for y, then let y = 0 and solve for x. Is the line dashed or solid? ...test one point to determine the side of the
solution region

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
