Answer:
17.3
Step-by-step explanation:
tens ones. tenths hundredths thousandths
1 7 . 2 5 3
We are rounding to the nearest tenth
We are rounding the 2 so we look at the 5. If it is 5 or above we round up.
Since it is, we will round the 2 to a 3
17.3
Answer:
4:1
Step-by-step explanation:
x+20 : y+20 = 5 : 2
(x+20)/(y+20) = 5/2
2(x+20) = 5(y+20)
2x+40 = 5y+100
2x = 5y+60 (1)
x-5 : y-5 = 5:1
(x-5)/(y-5) = 5/1
x-5 = 5(y-5)
x-5 = 5y-25
x = 5y-20 (2)
Solve (1) & (2) simultaneously,
2(5y-20) = 5y+60
10y-40 = 5y+60
5y = 100
y = 20
x = 5y-20
x = 5(20)-20 = 100-20
x = 80
x:y
80:20
4:1
Answer:(6,-2)
Step-by-step explanation:
M is the midpoint of AB then ,
M = ![\frac{A+B}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BA%2BB%7D%7B2%7D)
, ![-2=\frac{y-2}{2}](https://tex.z-dn.net/?f=-2%3D%5Cfrac%7By-2%7D%7B2%7D)
, ![-4=y-2](https://tex.z-dn.net/?f=-4%3Dy-2)
, ![y= -2](https://tex.z-dn.net/?f=y%3D%20-2)
so, B= (6,-2)
Answer:
[0, infinity)
Step-by-step explanation:
A square root can only use positive numbers, otherwise it becomes imaginary. A function needs to be real to output real values. Therefore, the domain is everything from 0 onwards.
