The midpoint between (2,-5) and (4, -7) is Option D.(3-6)
Step-by-step explanation:
Given:
Points (2,-5) and (4, -7)
To Find:
Midpoint of the points=?
Solution:
The midpoint that lies between the two points is given by
Where
= coordinates of the midpoint
= coordinates of the first point
= coordinates of the second point
we have,
Substituting the values in the mid point formula,
(x,y)=(3,-6)
Answer:
80
Step-by-step explanation:
You know that 20% of the school band are 16 clarinet players, or 16 is 20% of the band.
You can set up the equation 0.2x = 16 and divide both sides by 0.2. You then get that x = 80, so there are 80 kids in the school band.
Answer:
h(x) = 2x² -8x -10
Step-by-step explanation:
In the US, a quadratic is in standard form when the terms are listed in order of decreasing degree.
In the UK, a quadratic is in standard form when it is written in vertex form.
__
<h3>US</h3>
The only function with terms in order of decreasing degree is ...
h(x) = 2x² -8x -10
<h3>UK</h3>
All of the functions <em>except the last</em> are written in vertex form:
- f(x) = (x +1)² +0 . . . . . . . . would usually be written f(x) = (x +1)²
- y(x) = -(x -6)² +16
- g(x) = -3(x -3)² +4

<em>Additional comment</em>
Since the question asks about <em>one</em> function, we assume it is from the perspective of the US understanding of <em>standard form</em>. The point here is that "standard form" may vary from one tradition to another. (The "standard form" for numerical values varies by tradition, as well.)
