A)
y= 58x + 24
Change x and y and solve for y
x = 58y + 24
-24+x=58y +24-24
-24+x=58y
(x-24)/58=58/58y
(x-24)/58=y
y=(x-24)/58 (just switched around with y in front)
b)
Y=(x-24)/58
Y=(227-24)/58 (replaced x with 227)
Y=(203)/58=3.5
-8x + y = 6
in the first equation, isolate y and then it becomes...
y = 6 + 8x
use this to replace the y in the second equation.
7x - 1y = -4
let y = 6 + 8x
7x - (6 + 8x) = -4
7x - 6 - 8x = -4
-x - 6 = -4
x + 6 = 4
x = 4 - 6
x = -2
now use this x = -2 into the equation with y.
y = 6 + 8x
y = 6 + 8(-2)
y = 6 -16
y = -10
Therefore, x = -2 and y = -10

Answer:
(3, -5) (4, -5) (2, -7)
Step-by-step explanation:
An integer is any whole number that is not a fraction, they include -10204, -3, 0, 5, and 8592. (random numbers)
A coordinate with integers can be anything such as (0, 4582) and (547, 42)
However, it can not be (0.45846, 4579) or (54.42, 58).
To determine which points have coordinates that look like they are integers, you just have to select 3 points that lie at the intersection of the y and x value tic marks
You can see that (3, -5) is at the intersection of the x value 3 tic mark and the y value -5 tic mark, while also being on the parabola.
You need to post a graphic. I tried drawing my own, but I do not know where point "P" is nor where point "R" is.
23+52+34+61+30=200. Your answer of total gumballs is 200. At least I hope you meant to ask that. :)
