Answer:
Step-by-step explanation:
A. 2x+3y+z
X = -2
Y= -3
Z= 5
2(-2)+3(-3)+5
-4-9+5
=8
B. X-Y
-2–3
-2+3
=1
C. 2(x+y/z)
2(-2-3/5)
2(-1)
=-2
D. 3x^2-2x+1
3(-2)^2-2(-2)+1
3(4)+4+1
=17
E.3y(x+x^2-y)
3(-3)(-2+-2^2-(-3))
-9(1)
=-9
F.-z^2(1-2x)/y-x
5^2(1-2(-2)/-3–2
25(5/5)
25(1)
=25
Answer:
![d=5](https://tex.z-dn.net/?f=d%3D5)
Step-by-step explanation:
Distance Formula: ![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Simply plug in the 2 coordinates into the formula to find distance <em>d</em>:
![d=\sqrt{(4-1)^2+(-1-3)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%284-1%29%5E2%2B%28-1-3%29%5E2%7D)
![d=\sqrt{(3)^2+(-4)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%283%29%5E2%2B%28-4%29%5E2%7D)
![d=\sqrt{9+16}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B9%2B16%7D)
![d=\sqrt{25}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B25%7D)
![d=5](https://tex.z-dn.net/?f=d%3D5)
(-4n^(2))* (5n^(7)):-20n to the power of 9
(2x)^(3)*(5x^(4 ))^(2): 200x to the power of 11
Hi! Your answer is D explain below!
12%. since this 24/ 200 if you just divide it by 2 you get 12/ 100 meaning 12%
