Answer:
Step-by-step explanation:
This is asking what is A
Formula A squared + B squared = C squared
A=x
B=8
C=20
X^2+ 8^2=20^2
8 squared is 64
20 squared is 400
400-64 is 336
X*X=336 find the square root of 336 =18.3
CHECK
18.3*18.3+ 8*8=398.89 which is super close to 400
The |*| symbols take away the negative value of a number. So |-3| is just “3”. I can explain more if needed :)
Simple..
you have y which is the cost of the tickets..and you have x which is the number of tickets..
So, you have those points on the graph....find an equation!
Take any of those coordinates..and find the equation of the line...in the form of y=mx+b
(2,10) and (5,25)
Using:


Thus, you know your slope. m=5
But, remember it's in the form of y=mx+b
So, use any of the coordinates...let's use (2,10)
10=5(2)+b
10=10+b
0=b
Thus, your equation is... y=5x
Thus, your answer.
