2. 3/2x²
-1/2x²
1/4x²
5. -4x²-5 moves in 5 up on the y axis
6. I'm cant remember the trick to this one
7. This one should be D.
Hope This Helps!
Answer: 54ft^6
Step-by-step explanation:
Because you add then divide 42 and 5
I think that the ballance would be 204.40$
Thhe easiest way would be to solve for y first
4x=3y-7
add 7
4x+7=3y
divide both sides by 3
(4x+7)/3=y
try each
x=4
(4(4)+7)/3=y
(16+7)/3=y
(23)/3=y
7 and 2/3=y
(4,7.66666)
x=5
(4(5)+7)/3=y
(20+7)/3=y
(27)/3=y
9=y
(5,9)
x=6
(4(6)+7)/3=y
(24+7)/3=y
(31)/3=y
10 and 1/3=y
(6,10.333)
(4,7.66666)
(5,9)
(6,10.333)
when x=4, y=7 and 2/3
when x=5, y=9
when x=6, y=10 and 1/3

Answer: C) 0.02</h3>
====================================================
Explanation:
Any r values close to -1 or +1 represent strong correlation. Specifically, anything close to r = -1 is strong negative correlation, while anything close to r = 1 is strong positive correlation.
As you move closer to r = 0, the correlation weakens. The value r = 0.02 in choice C is the closest to r = 0, so this correlation is the weakest among the group of other r values.
