What is part A? I feel their is something you are missing in your answer
Intersect at where x=x and y=y
see where they have the same x and y values
that is at x=-1 and y=-5
intersect at (-1,-5)
Answer:
Sarah spent 45.76
Jack spent 38.16
Jack spent more on tax
Step-by-step explanation:
Sarahs game costs:
tax = 44 *.04 = 1.76
Total cost = game + tax
= 44 + 1.76
=45.76
Jacks game costs:
tax = 36 *.06 = 2.16
Total cost = game + tax
= 36 + 2.16
=38.16
Jack spent more on tax
5/9(f-32)=c
5/9f+5/9*-32=c: step 1
5f/9-160/9=c: step 2
5f/9-160/9+160/9=c+160/9: step 3
5f/9=160/9*9+c*9: step 4
5f/5=160/5+9c/5: step 5
f=32+(9c/5): answer
