All of the equations have a graph that is reflected over the x axis. So look at the maximum point/ the vertex of the graph.
1) has vertex (3,4)
2)has vertex (-3,4)
3)has vertex (4,3)
4)has vertex(-4,3)
The functions should look the same, the only difference is the vertex.
Answer:
21 divided by 2 and 2/3 = 11.1666667
Step-by-step explanation:
The answer is 3x squared -11x-10
Answer:
60
Step-by-step explanation:
There are 2+5 = 7 ratio units of students. If we multiply the numbers by 5, we can have a total of 35 ratio units of students: 10 : 25.
Now, we can substitute this into the ratio of teachers to students:
teachers : students = 3 : 35
teachers : (male students : female students) = 3 : (10 : 25)
Then the number of teachers is seen to be 3/25 of the number of female students:
(3/25)(500) = 60 . . . teachers
