Based on the graph given, it can be deduced from the computation that the value of y will be -8.
Point C is given as (-10 , -2) and D = (10 , 6)
The Slope of line CD = ( 6 - (-2) /( 10 - (-10) = 8/20 = 2/5
Since EF is parallel to line CD
, the slope of EF = 2/5
Equation y = (2/5)x + c
5y = 2x + 5c
It passes through F ( 6 , -4)
= 5(-4) = 2*6 + 5c
= -20 = 12 + 5c
5c = -32
5y = 2x - 32
Point E ( - 4 , y)
5y = 2(-4) - 32
5y = -8 - 32
5y = -40
y = -8
Therefore, the value of y is -8.

Based on the calculations, the molar solubility of AgCl in 0. 500 M of NH₃ is equal to 2.77 × 10⁻² M.
<u>Given the following data:</u>
- Ksp of mg(oh)₂ = 1.8 × 10⁻¹⁰
- Concentration of NH₃ = 0.500
- Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷
<h3>How to determine the molar solubility.</h3>
First of al, we would write the properly balanced chemical equation for this chemical reaction:
Ksp = 1.8 × 10⁻¹⁰
Kf = 1. 7 × 10⁷
K = Ksp × Kf
K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷
K = 3.06 × 10⁻³
Mathematically, the Ksp for the above chemical reaction is given by:
x = 2.77 × 10⁻² M.

Answer:
Explanation:
so basically f(g(x)) is telling you to plug the entire g(x) equation into x in the f(x) equation so it will look like this
2() + 1
and then simplify
The maximum number of devices that are supported by internet access points and wireless routers corresponds to about 250 devices connected at the same time, such as internet-enabled smartphones, cameras, computers and home appliances.
<h3 /><h3>How to choose an internet plan?</h3>
It is necessary for the user to choose his internet plan based on his access needs, taking into account four essential factors:
- Speed
- Number of connected devices
- Users
- Provider characteristics
Therefore, hiring a broadband internet plan must be carried out based on the user's needs, who must also be aware of the importance of information security and the quality of the internet provider service.
