Answer: m=−y+3−x+2
x=2m+y−3m
Step-by-step explanation:
m(2−x)=3−y
Step 1: Factor out variable m.
m(−x+2)=−y+3
Step 2: Divide both sides by -x+2.
m(−x+2)−x+2=−y+3−x+2
m=−y+3−x+2
__________________________________________________
m(2−x)=3−y
Step 1: Add -2m to both sides.
−mx+2m+−2m=−y+3+−2m
−mx=−2m−y+3
Step 2: Divide both sides by -m.
−mx−m=−2m−y+3−m
x=2m+y−3m
Answer:
Sharon can paint faster
Step-by-step explanation:
210/3=70, Sharon
80/12=6.66, Zeke
Decay every two years over a period of t years:
Fourth option: f(t)=(0.75)^(t/2)
decay 2 times a year over a period of t years:
Second option: f(t)=(0.9306)^(2t)
Sixth option: f(t)=(0.8660)^(2t)
decay once per year over a period of t years:
First option: f(t)=(0.9306)^t
Third option: f(t)=(0.8660)^t
In each case, you can start by taking the antilog.
21. x = 4^(3/2)
x = 822. 81 = x^(4/3)
81^(3/4) =
x = 2724. 2x - 3 = 6^0
2x = 4 . . . . . add 3
x = 225. 5 - x = 16^(1/2)
5 - 4 =
x = 1_____
You're using the relationship of logarithms:
