x=12
x/16-1-4=1/2
multiply by both sides
x-4=8
move constant to the right side of and change its sign
x=8+4
add the numbers
x=12
Answer:
a.) 9, -9
b.) 2(sqrt)15, -2(sqrt)15
c.) 4, -2+2i(sqrt)3, -2-2i(sqrt)3
d.) 3(sqrt)75
(some of the numbers are placed differently than I wrote them so here are screenshots- pls look at them rather than what I wrote ;w;)
The question is just a black box. I would like to help you if you could attach a pic of the problem

Answer:
The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65
Step-by-step explanation:
Let x be the number of t-shirts and y be the total pay
As we can clearly see in the table that there is a linear relationship between x and y
A linear function is given as:
![y = mx+b](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb)
Here m is the gradient of the function then
![m = \frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Taking any two pairs of x and y
(1,68) and (2,71)
![m = \frac{71-68}{2-1}\\m = 3](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B71-68%7D%7B2-1%7D%5C%5Cm%20%3D%203)
Putting in equation
![y = 3x+b](https://tex.z-dn.net/?f=y%20%3D%203x%2Bb)
Putting a pair (1,68) in the equation to find the value of b
![68 = 3(1) + b\\68 = 3+b\\b = 68-3\\b = 65](https://tex.z-dn.net/?f=68%20%3D%203%281%29%20%2B%20b%5C%5C68%20%3D%203%2Bb%5C%5Cb%20%3D%2068-3%5C%5Cb%20%3D%2065)
Putting the value of b
![y = 3x+65](https://tex.z-dn.net/?f=y%20%3D%203x%2B65)
Let p(x) be the linear function
Hence,
The linear function is: p(x) = 3x+65
