Answer:
An inequality.
Step-by-step explanation:
This gives the range of values that y can take.
It can equal 18 or be greater than eighteen but it also could be 30 or less than thirty.
WE read the signs starting from y to the left and to the right.
So y is greater or equal to 18 and less than or equal to 30.
Answer:
21
Step-by-step explanation:
25-4=21
All of the questions are 25, he hasn't answered 4, so fron 25 you remove 4, and the answer is 21.
25% of 80
25/100 or 1/4 x 80 = 20
So $20 were spent on shorts, then $60 were left over.
65% of 60 on sandals.
so 65/100 x 60 = 39
So we can see that the sandals cost $39.
Answer:
No, the maximum height that the balloon can reach is 9ft.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
The function h(x) =-0.5(x-4)² +9, is a Quadratic Function in the Vertex form.
Vertex form: f (x) = a(x - h) 2 + k
Where:
- (h, k) is the vertex of the parabola-
- h is the horizontal shift (how far left, or right, the graph has shifted from x = 0).
- k represents the vertical shift (how far up, or down, the graph has shifted from y = 0).
In this case a = -0.5, it means that the parabola opens downward and has a maximum point at the vertex.
So, the maximum height that the balloon can reach is k=9ft.
9 ∠ 12
The balloon will not hit the ceiling 12 ft above the pool.
Feel free to ask for more if needed or if you did not understand something.
