X + 2y = -6
2y = -x - 6
y = (-x - 6)/2
answer is D. Last one
y = (-x - 6) / 2
It’s an exponential function
For part A)
Let's make a function for each person, and then combine them to find total calories
Gwen burns 10 cal/min, and had already burned 100 calories when Tristan and Keith started (Yg=100 when x=0)
Yg= 10x + 100
Tristan burns 125 cal every 10 minutes, or 12.5 cal every minute.
Yt= 12.5x
Keith burns 300 calories every 30 min, or 10 calories every minute.
Yk= 10x
Add Yg, Yt, and Yk to find the general function y:
y=10x +100 + 12.5x + 10x
y = 32.5x + 100
In step 3, it is supposed to be 12 + 9 · 2, not 36 ÷ 12 · 2. (Not supposed to add 3 and 9. Do 36 ÷ 3 instead (order of operations))
