Answer:
Step-by-step explanation:
a.
2y - 3x = 5
2(-2) - 3x = 5
-4 - 3x = 5
-3x = 9
x = -3
(-3,-2) is another solution
b.
(-1,1)
2y - 3x = 5
2(1) - 3(-1) = 5
2 + 3 = 5
5 = 5
true, the point is a solution to the equation because the equation is true after substituting x and y with the point (-1,1)
(4,1)
2y - 3x = 5
2(1) - 3(4) = 5
2 - 12 = 5
-10 = 5
not true, the point is not a solution to the equation because the equation is not true after substituting x and y with the point (4,1)
c. You can use the points from the given (-1,1) and (-3,-2) to form a line. You then shade whichever half solves the solution using points on the graph.
The answer is B., valid because people were chosen randomly
This would make it a valid survey
Hope this helps!

Answer:
What is it rounded up to???
Step-by-step explanation:
I believe you just add all the numbers then divide by how many were there. You would divide by 16.
Answer:
$96
Step-by-step explanation:
if 1/4 is 24, then 1 is 6. this is like a ratio where it is like 25:24, as in 25%. if you x4 to get 100%, 24 becomes 96.
