Find the midpoint of A and B where A has coordinates (2,7)<br> and B has coordinates (6,3).
Veronika [31]

Given that the coordinates of the point A is (2,7) and the coordinates of the point B is (6,3)

We need to determine the midpoint of A and B

<u>Midpoint of A and B:</u>

The midpoint of A and B can be determined using the formula,

Midpoint =(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

Substituting the points (2,7) and (6,3) in the above formula, we get;

Midpoint =(\frac{2+6}{2}, \frac{7+3}{2})

Adding the numerator, we have;

Midpoint =(\frac{8}{2}, \frac{10}{2})

Dividing the terms, we get;

Midpoint =(4, 5)

Thus, the midpoint of the points A and B is (4,5)

you deposit $7,900 in a money-market account that pays an annual interest rate of 4.3%. the interest is compounded quarterly. ho
Sladkaya [172]
<span><span>anonymous </span> 3 years ago</span>we are solving for A, A is the future amount A=? P is the present value, so we were told 7,900, so p=7900 r is the interest rate, so 4.3%, but in decimal form so r=0.043 k is the how often it is 'compounded', it says quarterly, so k=4 n is how long, 3 years, so n=3 <span>A=P(1+<span>rk</span><span>)<span>n∗k</span></span></span> plug in the values
<span>A=8981.51</span>

How do you do 43? I'm really confused.
Sunny_sXe [5.5K]
Remove parenthesis on m-2 because you don't need to distribute ( you have an invisible 1, but it won't change the values bc it's a one) Combine your like terms on the side you removed the parenthesis. m-2-5   ->   m-7. Now on  the other side distribute the 2 to the terms in the parenthesis.  once you've done that your equation should look like this 8- 2m +8. now lets look at th full equation. m-7=8-2m+8 move the -2m to the other side, by adding. you now have an equation like this 3m- 7=16. move the -7 to the other side by adding. 3m=23. divide 23 by 3. you're answer should be m= 23/3 
its best to leave your answer as a fraction.  
Hope this helped. (:
