Answer:
A: y=1/3x+5
B: y=-2x+9
C: y=-3
D:y=2x+9
E: y=-10x+80
F:y=x-2
#1 rodney's error for
y=30x+10 is that he started off at 30 but he had to start off at 10 so it starts at (0,10) (1,40) (2,70) and keep going on by adding one to the x value and 30 to the y value
#2 rodneys error for
y=-1/2x+5 is that he went up by 1/2 instead of going down. it's a negative 1/2 so he had to go down
#3 Rodneys error for
y=x-2 is that he didn't start at (0.-2)
I'm not sure about the last picture but i think that it's

Step-by-step explanation:
512 is 64/2 x 16 in the end.
3x+22=10x-41
-22 -22
----------------------
3x=10x-63
-10x -10x
-----------------
-7x=-63
divide by -7 on both sides
yep ur right its x=9
X^2 - 6x + 2 = 0
Completing the square:-
(x - 3)^2 - 9 + 2 = 0
(x - 3)^2 = 9 - 2 = 7
x - 3 = +/- √7
x = 3 + √7 and 3 - √7 Answer
Answer:
<em>Choice C is correct because -4 + 4 = 0 as required.</em>
Step-by-step explanation:
<u>Addition and Subtraction</u>
The number line shown in the image indicates the integer +4.
We need to find a number that added to 4 results in 0.
Choice A is not correct because 4 + 4 = 8
Choice B is not correct because -1/4 + 4 = 15/4
Choice C is correct because -4 + 4 = 0 as required.
Choice D is not correct because 1/4 + 4 = 17/4
