7(2y+1)+3y
14y + 7 + 3y
17y + 7
Answer: 
<u>Step-by-step explanation:</u>
(1, 2) and (4, -3)
First, find the slope (m): 
m = 
= 
Next, choose ONE of the points and input the point and slope into the Point-Slope formula: y - y₁ = m(x - x₁)
y - 2 =
(x - 1)
y - 2 =
+ 
y =
+ 
Then, determine which inequality symbol will result in (-2, 8) being False (since it is not a solution):
y ___
+ 
8 ___
+ 
8 ___ 
8 >
so ≤ makes the statement False
⇒ y ≤
+ 
****************************************************************
If you need a "system" of inequalities, then you need another equation.
There are infinite possibilities. Graph the points to see what works.
y < 8 or x > -2 are two examples.
---> I just realized that the system can be simpler than what I did above:

17q you have to subtract to get the answer
Answer:
A) 3hrs
Step-by-step explanation:
Fission is the action of dividing or splitting something into two or more parts.
So, we're going to continuously multiply our answers by 2 until we get 360
10 x 2 = 20 30min
20 x 2 = 40 1hr
40 x 2 = 80 1hr 30min
80 x 2 = 160 2hrs
160 x 2 = 320 2hrs 30min
320 x 2 = 630 3hrs
