X=5, y=-4
(5,-4)
do you need the work?
I believe it's the 3rd one. It's a really tricky question sorry if you get it wrong
Answer: C) Tracy spends $7 every 4 days
Graphing the function as well as x = 4 will show that there is a difference in the y-value of 7 between x=0 and x=4, meaning she spends $7 every 4 days.
4x-30=2x+50
+30 +30
4x=2x+80
-2x -2x
2x=80
/2 /2
X=40
4(40)-30=130°
2(40)+50=130°
180-130=50°
Angle 7=50°
1kg = 2.205 lbs
Therefore, 1 lb = 1/2.205 kg
Or 5.4lb = 5.4/2.205
= 2.44 kgs
Thus, this package will weigh 2.44 kgs
