Answer:
Chelsea spent more than $12.75
Step-by-step explanation:
To solve this problem we should understand the meaning of signs first.
sign (<) → less than
sign (>) → more than
sign (=) → equal to
sign (≤) → Not more than
sign (≥) → At least
If the statement is,
"Chelsea spent more than $12.75"
d > 12.75
Therefore, Chelsea spent more than $12.75 is the correct statement.
We conclude that the interval in which the function decreases is (1.5, 3]
<h3>
In which interval is the ball's height decreasing?</h3>
The ball is decreasing when the graph, reading from left to right, is going downwards.
Particularly, in this parabola that opens downwards, the graph will decrease after the vertex.
And we can see that the vertex is at x = 1.5
And we also see that the graph of the function ends at x = 3.
Then we conclude that the interval in which the function decreases is (1.5, 3]

Answer:
Triangle Sum Theorem
Step-by-step explanation:
Statement
2. m∠H + m∠J + m∠K = 180°
Reason
Triangle Sum Theorem
Comments
-----------
In any given triangle the sum of its interior angles must be equal to 180º.
This has to do with lines and parallelism, and if you trace a Triangle and to parallel lines one of them being the base of it, this can be proven too.
Check it out below.
If a factor is x+4, that means that the coefficient of x^2 (the number in front of it, which would be 1) and that 20 should be divisible by 20. Now, if you divide 20 by 4, you would get 5, and 1/1 = 1. So, the 2 factors you have is
(x+4)(x+5)
When you FOIL, you would get
x^2+9x+20, which means
b=9
