7.) the equation of the circle is
(x - 3)^2 + (y - 4)^2 = 25
If you substitute the point in you get
(6-3)^2 + (8-4)^2 = 25
3^2 + 4^2 = 25
9 + 16 = 25
25 = 25
Both sides of the equation are the same so it proves it lies on the circle
8.) you add the x coordinates together and divide by 2
7 + 4 = 11
11/2 = 5.5
You use +7 because you need to find the midpoint.
You then add 5.5 to - 7 or - 5.5 from 4
-7 + 5.5 = - 1.5
You do the same for y coordinates
6+5 = 11
11/2 = 5.5
6-5.5 = 0.5
So the coordinates of Rachel's house are
(-1.5, 0.5)
Answer
A. 196,608
Step-by-step explanation:
-12/3 = -4
48 / -12 = -4 and -192 / 48 = -4
This is a geometric sequence with common ratio -4.
an = a1 r^(n -1) so:-
9th term (a9) = 3*(-4)^(9-1)
= 196,608
Answer
the probility is 9
Step-by-step explanation:
Answer:
Step-by-step explanation:
What two number multiply to equal 6*(-12) and add to equal -1? That is -9 and +8.
Now factor by grouping
Answer:
2 miles from your house
Step-by-step explanation:
you walked 3 miles to the store so you are now 3 miles away.
you meet a friend and walk 1 mile in the direction of your house.
now there is 2 miles left.
3 - 1 = 2
