The first table : y=4x
the second table: y=1.5x
the third table: y= 1.25x
if you want help on how to do it: plug each of those equations into the “desmos” graph! from looking at those table points (x,y) you can find which equation matches the table
for instance on table one: I put y=4x into desmos then looked at graph one, I chose the point (2,8) I went to 2 on the x axis and moved my finger up 8 and that point was directly on the line meaning that table matches the equation. be sure to also do the same thing with the other points to double check!
So first you distribute the negative to the 6x and 13 which will flip the sign of both of them to -6x and -13 so take away the parentheses and the equation is now 7x-6x-13. You combine the x’s and you get 1x-13 or x-13
X = 23
x - 7
(23) - 7 = 16
16 is your answer
hope this helps

Answer:
Approximately 35, or 34.67
Step-by-step explanation:
You can set up a cosine (adjacent over hypotenuse) equation.
cos38 = x/44
Move the 44 over and plug into the calcultaor.
x = 44cos38
(make sure the mode is on degree and not radian!)
