Answer:
Step-by-step explanation:
The first step is to use the Distance Formula to figure out the lengths of the two legs:
![\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D](https://tex.z-dn.net/?f=%5Csqrt%7B%5B-x_1%20%2B%20x_2%5D%5E%7B2%7D%20%2B%20%5B-y_1%20%2B%20y_2%5D%5E%7B2%7D%7D%20%3D%20D)
R(1, 1) and P(−1, −2) ↷
![\sqrt{[1 + 1]^{2} + [2 + 1]^{2}} = \sqrt{2^{2} + 3^{2}} = \sqrt{4 + 9} = \sqrt{13}\\ \\ \sqrt{13} = RP](https://tex.z-dn.net/?f=%5Csqrt%7B%5B1%20%2B%201%5D%5E%7B2%7D%20%2B%20%5B2%20%2B%201%5D%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B2%5E%7B2%7D%20%2B%203%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B4%20%2B%209%7D%20%3D%20%5Csqrt%7B13%7D%5C%5C%20%5C%5C%20%5Csqrt%7B13%7D%20%3D%20RP)
Q(2, −4) and P(−1, −2) ↷
![\sqrt{[1 + 2]^{2} + [2 - 4]^{2}} = \sqrt{[-2]^{2} + 3^{2}} = \sqrt{4 + 9} = \sqrt{13} \\ \\ \sqrt{13} = QP](https://tex.z-dn.net/?f=%5Csqrt%7B%5B1%20%2B%202%5D%5E%7B2%7D%20%2B%20%5B2%20-%204%5D%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B%5B-2%5D%5E%7B2%7D%20%2B%203%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B4%20%2B%209%7D%20%3D%20%5Csqrt%7B13%7D%20%5C%5C%20%5C%5C%20%5Csqrt%7B13%7D%20%3D%20QP)
* So, by my calculations, we have an isosceles <em>right triangle</em>, and according to the <em>45°-45°-90° triangle theorem</em>, we automatically know that the hypotenuse, <em>RQ</em>, is 
:

So now, we have to find the area of the triangle by taking half of either height or base, then multiplying that by the height or base, but since this is an isosceles <em>right</em><em> </em><em>triangle</em><em>,</em><em> </em>it does not matter:

I am joyous to assist you anytime.
3n + 4 = 7
3n + 4 (-4) = 7 (-4)
3n = 3
3n/3 = 3/3
n = 1
hope this helps
Answer:
Slope = -3/5
Step-by-step explanation:
slope (m) = y2 - y1 / x2 - x1
m = -2 - 1 / 1 - -4
m = -3 / 1 + 4
m = -3 / 5
You can check the work by counting rise (-3 which means 3 units down) over run (5 which means 5 units to the right)
Answer:
Nope
Step-by-step explanation:
y = 6x - 2
(1, 2)
2 = 6(1) - 2
2 = 6 - 2
2 = 4
(1, 2) isn’t on the line
ANSWER
3438
EXPLANATION:
<em>PARENTHESIS FIRST</em>
32 x 8 = 256
17 x 4 = 68
256 - 68 = 188
(<u>now the equation is, 6³ ÷ 4 + 2 x 9 (188))</u>
<u />
<em>EXPONENTS NEXT</em>
6³= 216
(<u>now the equation is, 216 ÷ 4 + 2 x 9 (188))</u>
<u />
<em>MULTIPLICATION AND DIVISION NEXT (left to right)</em>
216 ÷ 4 = 54
2 x 9 = 18
18 x 188 = 84
(<u>now the equation is, 54 + 3384)</u>
<u />
<em>LASTLY ADDITION AND SUBTRACTION (left to right)</em>
54 + 3384 = 3438
Ta-da!
