M - 536 <== ur expression
when the mass is 781 grams...
781 - 536 = 245
so the mass of the package is 781....and when it is reduced by 536 grams, it equals 245 grams
Here are the steps
put it into y=mx+b 4y=-5x+20
to isolate y divide both sides by y=-5/4+5
to find the xi
xi is when y=0 so plug it in to the equation 4y=-5x+20 4(0)=-5x+20
0=-5x+20 subtract 20 from each side -20=-5x the negatives cancel out 20=5x
to isolate x divide each side by 5 x=20/5
20/5=4
Answers:
m=-5/4
yi=5
xi=4

Step-by-step explanation:
Answer:
The 2nd and last options.
Step-by-step explanation:
By looking at the table we know that the 2nd one is an answer for sure.
Also by looking at the table we know that the 3rd and 4th are not true.
put in -1/2 in the function to see if you get -2
1/2(-1/2)+3/2
-1/4+3/2
-1/4+6/4
5/4
So The first one doesn't work either.
Now the last one:
1/2(4)+3/2
4/2+3/2
7/2
So the last one works too.
Hope this helps :)
