Please help me i need the medien for this

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours

x:       y:  

-1         4

0         4

1         6

2         18

3         20
