Answer:
3
Step-by-step explanation:
First equation :
x = 3 - y
Substitute into the second equation.
2(3 - y) - y = 6
6 - 2y - y = 6
6 - 3y = 6
-3y = 0
y = 0
Substitute back into the first equation.
x + 0 = 3
x = 3
The x coordinate is 3.
The equation of the inverse function is given as n(t) = (t+3)/4
<h3>Inverse of a function</h3>
Given the function that is represented as;
![t(n)=8\cdot\frac{n+3}{2}](https://tex.z-dn.net/?f=t%28n%29%3D8%5Ccdot%5Cfrac%7Bn%2B3%7D%7B2%7D)
This is further simplified to have:
t(n) = 4(n + 3)
Replace t with t(n)
t = 4n - 3
Make n the subject of the formula
4n = t+3
n = (t+3)/4
Hence the equation of the inverse function is given as n(t) = (t+3)/4

The correct answer is f(x)=-5+0.5x
Looking at the data, we can see that the data increases at a constant rate. We can find this rate, the slope, using the formula
m=(y₂-y₁)/(x₂-x₁)
Using the first two ordered pairs, we have
m=(1-0.5)/(12-11) = 0.5/1 = 0.5
Writing this in point-slope form, y-y₁=m(x-x₁), we have
y-0.5=0.5(x-11)
Using the distributive property, we have
y-0.5=0.5x-0.5*11
y-0.5=0.5x-5.5
Adding 0.5 to both sides,
y-0.5+0.5=0.5x-5.5+0.5
y=0.5x-5
