X=3
It’s a right angle so it's equal to 90 degrees and both sides are congruent.
Answer:
y=x+5.99
Step-by-step explanation:
A poster and 2 comics cost $7.99
(2,7.99)
A poster and 11 comics cost $16.99.
(11,16.99)
Let y be the cost of package and x be the no. of comics
We will use two point slope form :
(x1,y1) = (2,7.99)
(x2,y2) = (11,16.99)
Formula :
y-y1 = y2-y1/x2-x1(x-x1)
Substitute the values:
Hence a linear function rule that models the cost y of a package containing any number x of comic books is y=x+5.99
