The correct answer is 6+x-y.
This is because the other answer choice is a binomial and not a trinomial (which contains three terms). A term is always separated by - or + signs.
I'll do #6.
The axis of symmetry is the x-coordinate of the vertex, which in this case, is (0,-4). So the axis of symmetry is x=0.
The vertex is in the above answer. Since this is a quadratic function, there are no boundaries, the domain is All Real Numbers.
The range goes up forever <em>from </em><em>the vertex. </em>The vertex is (0,-4), so, the minimum y value is -4. The range is y is greater than or equal to -4, or in interval notation: [-4,infinity]
Hope this helps!
Answer:
81 students.
Step-by-step explanation:
If 10% of the 90 students were absent, then that means that 9 students were absent. To find the number of students present, simply subtract.
90 - 9 = 81.

First calculate th feet of lace she haven't used.
9 - 3 = 6 ft
now we can convert feet into yard. we can divide the amount into 3 because it says 3ft is 1yrd
6 / 3 = 2 yards
