Answer:
35 ways
Step-by-step explanation:
7×6×5×4. 7×6×5×4
--------------. = --------------. = 35
1x2×3×4. 1×2×3×4
−8x + 4y = 24 -- (1)
−7x + 7y = 28 -- (2)
Eqn (1) & (2) are simplified as
y - 2x = 6 -- (3)
y - x = 4 -- (4)
By making y the subject of formula in (4), we have
y = x + 4 -- (5)
Substitute x + 4 for y in (3), then
x + 4 - 2x = 6
x - 2x = 6 - 4
- x = 2
x = - 2.
Substitute - 2 for x in (5), then
y = - 2 + 4
y = 2.
Therefore, (x, y) = (- 2, 2) ...Ans.
In the top the "f(x)" equals 9, now they are asking you to add onto the 9 by 1 causing it to be 10. If you did the first few you would have noticed that it takes 9 in order to get to 5 from -4.
here are the answers btw:
Answer:

Step-by-step explanation:
if you follow the points, this is the only answer choice that doesnt repeat any line segments
If you're talking about the second part of the question where it asks you which facts you included in your answer, you can choose any of them and it will be counted right.
