Answer:
<u>(-1 , 7)</u>
Step-by-step explanation:
To find the midpoint, the equation used is:-
![\frac{x1 + x2}{2} , \frac{y1 + y2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx1%20%2B%20x2%7D%7B2%7D%20%2C%20%5Cfrac%7By1%20%2B%20y2%7D%7B2%7D)
Here, the values are:-
x1 = 1
x2 = -3
y1 = 9
y2 = 5
Substituting these in the equation, we get:-
![\frac{-3 + 1}{2} ,\frac{9+5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%20%2B%201%7D%7B2%7D%20%2C%5Cfrac%7B9%2B5%7D%7B2%7D)
![\frac{-2}{2} ,\frac{14}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2%7D%7B2%7D%20%2C%5Cfrac%7B14%7D%7B2%7D)
(-1, 7)
They are like a line graph but they are points in a graph to show you how much more something is compared to something else
Answer:
8x^2 + 6x + 36xy^2 + 24y^2
Step-by-step explanation:
First, multiply the two terms inside the second set of parentheses by-2x; we get 8x^2 + 6x.
Next, multiply the same two terms by -9y^2; we get 36xy^2 + 24y^2.
Now add these products together:
8x^2 + 6x + 36xy^2 + 24y^2 This is the desired product.
Answer:
37.5%
Step-by-step explanation:
Math
4/(√<em>x</em> - √(<em>x</em> - 2)) × (√<em>x</em> + √(<em>x</em> - 2))/(√<em>x</em> + √(<em>x</em> - 2))
= 4 (√<em>x</em> + √(<em>x</em> - 2)) / ((√<em>x</em>)² - (√(<em>x</em> - 2))²)
= 4 (√<em>x</em> + √(<em>x</em> - 2)) / (<em>x</em> - (<em>x</em> - 2))
= 4 (√<em>x</em> + √(<em>x</em> - 2)) / (<em>x</em> - <em>x</em> + 2)
= 4 (√<em>x</em> + √(<em>x</em> - 2)) / 2
= 2 (√<em>x</em> + √(<em>x</em> - 2))
