Answer:
Step-by-step explanation:
Use the midpoint formula: 
So, the Change In X is 2-8 = -6
And the Change in Y is 7-4 = 3
Once you divide both of the changes by 2, you get
X: -3
Y: 
So the midpoint is: 
-8.8 is the simplify expression and as well as the exact value
Answer: Hadassah is 12.
Explanation:
x=Hedya
y=Hannah
z=Hadassah
x+y+z=102
x=4y
y=1.5z
z=?
4x1.5z=6z (also x or Hedya's age)
z+1.5z+6z=102
8.5z=102
z=12
1.
f(x) = x
g(x) = x + 3
For each x value you use in f(x) and g(x), the corresponding y value in g(x) is always 3 more than in f(x). If each y-coordinate is 3 more, that means the graph is shifted 3 units up. The graph of f(x) is shifted 3 units up to create the graph of g(x).
2.
The first term is -0.5.
Then each term goes up by 0.25.
1st term: -0.5
2nd term: -0.5 + 0.25 = -0.5 + 0.25(1)
3rd term: -0.5 + 0.25 + 0.25 = -0.5 + 0.25(2)
4th term: -0.5 + 0.25 + 0.25 + 0.25 = -0.5 + 0.25(3)
nth term: -0.5 + 0.25(n - 1)
-0.5 + 0.25(n - 1) = -0.5 + 0.25n - 0.25 = -0.75 + 0.25n = 0.25n - 0.75
Answer is C.
Answer:
D = 9.4868
Step-by-step explanation:
The expression is the following
D = √((x2-x1)^2+(y2-y1)^2)
Where
(x1,y1) = (4,6)
(x2,y2) = (7,-3)
D = √((7-4)^2+(-3-6)^2)
D = √((3)^2+(-9)^2)
D = √(9+81)
D = √(90)
D = 9.4868
