Step-by-step explanation:
Answer:
The coordinates of the point X:
Step-by-step explanation:
Let X be the point.
As the point X is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6
i.e.
Rise = y₂ - y₁
Run = x₂ - x₁
1 : 6 ratio means the point X lies at
Thus,
rise for X 
run for X
Thus, coordinates of X will be:
Therefore, we conclude that:
The coordinates of the point X:
Answer:
1-2y+y^2
Step-by-step explanation:
(1–y)^2
(1-y) * (1-y)
FOIL
first: 1*1 =1
outer: 1*-y = -y
inner: -y *1 = -y
last: -y*-y = y^2
Add together: 1+-y-y+y^2
1-2y+y^2
Answer:
Kim is 16 years old and her sister is 8 years old.
Step-by-step explanation:
We can use equations to represent this scenario.
Let Kim's age be 'k' and her sister's age be 's'.
Thus, k=2s (since Kim's age is double of her sister)
and k+s=24 (their ages add to 24 (from question)
Substituting the first equation:
2s+s=24
3s=24
s=8
Therefore, Kim's sister is 8 years old.
Now substitute this value into the second equation:
k+8=24
k=16
Therefore, Kim is 16 years old.
Answer:
x=-3, y=9. (-3, 9).
Step-by-step explanation:
-9x-5y=-18
4x+5y=33
---------------
-5x=15
x=15/-5
x=-3
4(-3)+5y=33
-12+5y=33
5y=33-(-12)
5y=33+12
5y=45
y=45/5
y=9
