Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
S(-1,5) and T(7, -2)
The midpoint is
We have the final answer as
Hope this helps you
Take a quadratic equation in standard form:
If there exists a sum of two numbers that equal b, whose addends produce a product that equals c. You can rewrite the quadratic as a product of two binomials.
For example take
When thought through throughly, -5 had addends, -2 and -3 that produce 6 when multiplied
Thus, we can rewrite the quadratic as.
Looks like the equation is
Differentiating both sides yields the linear ODE,
or
Multiply both sides by the integrating factor 
:
Integrate both sides, then solve for 
:
The given answer choices all seem to be missing <em>C</em>, so I suspect you left out an initial condition. But we can find one; let 
, then the integral vanishes and we're left with 
. So
So the particular solution is
He was wrong, you cannot make 10 coins by adding 32 coins to 28 coins. If you want to obtain 10 coins from 32 coins and 28 coins, you can subtract 28 coins from 32 coins.
This can be illustrated as follows:
32-28=10
Quadrilateral. If you add the angles up on any quadrilateral, it equals 360 (it should always add to 360 for a quadrilateral)
