Answer:
I don't no sorry for that
There is none except for eleven and that is it
Answer:
Step-by-step explanation:
Amari= Graph C and Solution is (-6,-2)
Bella= Graph A and Solution is (3,4)
Carl= Graph B and Solution is (0,-3)
0 solutions because the slopes are the same. The lines will never cross because they are at the exact same angle.
No, I do not agree with Joey because the lines have different slopes and will lead to the system cross which is the solution.
1st graph: y=2x-1 and y=7 solution #1= (4,7)
2nd graph: y=-2x-3 and y=1/2x solution #2= (-2,1)
3rd graph: y=x and y= -1/5+6 solution #3= (5,5)
I had this exact same assignment a few months ago, my teacher didn't use the 2nd slide but I had the 1st and 3rd slide so this should help!
Answer:
28. 120 degrees
29. 30 degrees
30. 56 degrees & 124 degrees
31. 72 degrees, 108 degrees, and 18 degrees
Step-by-step explanation:
We assign variable x for the answer we are looking for (28-29).
28.
Supplement means x + y = 180 degrees. We also know x = 2y. Substitution gives us 3y = 180 degrees, so y = 60 degrees and x = 120 degrees.
29.
Complement means x + y = 90 degrees. We are given 2x = y. Substitution brings us 3x = 90 degrees, x = 30 degrees.
30.
Supplement means x + y = 180 degrees. We are told that y = 2x + 12, so we substitute. This gives 3x + 12 = 180 degrees, x = 56 degrees. Substituting that back into the equation for y, we get 124 degrees.
31.
Supplement means x + y = 180 degrees. Complement means x + z = 90 degrees. Using our given info, we know y = 6z. We can substitute that in to get x + 6z = 180. Subtracting our second and third equations, we get 5z = 90, z = 18 degrees. Therefore, x = 72 degrees, y = 108 degrees.
Measure of angle 2 would be 130 degrees because since it forms a linear pair the two angles added together have to equal 180 degrees so
180 - 50 = 130
