Step-by-step explanation:
Here is some answers
1. 2x+3y=1,470
-2x -2x
---------------------
3y=-2x+1,470
---- --------
3 3
------------------
y=-2x+490
2. rise
-----
run
y=-2

1
Find 490 and either go up 2 down 1 or down 2 up 1 either way you will get a straight line.
3. f(x)=2x+490
Don-t know how to explain this :(
I'm confused after this question
Hope this helped a little
3) y^2 - 1 = 24
add 1 to each side:
y^2 = 25
Take square root of each side: y = √25
y = 5 or -5
4) y^2 - 1 =48
Add 1 to each side:
y^2 = 49
Take square root of each side:
y = 7 or -7
