-1/3m+1=-7
-1/3m+1-1=-7-1 subtract 1 from both sides
-3(-1/3m)=-3(-8) multiply -3 on both sides
m=24 solution
We will plug in x = 24, and y = 6:
All is wrong except:
6 = 1/4 · 24
Answer:<span> D ) y = 1/4 x</span>
81^(-1/4) is the same as the fourth root of (1/81). Which can be written as 4th root of 1 divided by the 4th root of 81.
The 4th root of 1 is 1 (because 1x1x1x1x1=1).
The 4th root of 81 is 3 (because 3x3x3x3=81).
So 81^(-1/4) = 1/3
Answer:
8 pounds of apples.
Step-by-step explanation:
5 pies need 2 pounds of apples.
so 1 pie needs 2/5 pounds
- and 20 pies needs 20 * 2/5
= 40/5
= 8 pounds of apples.
Step-by-step explanation:
a) Tangent equals sine divided by cosine. Therefore:
tan(-t) = sin(-t) / cos(-t)
b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):
tan(-t) = -sin(t) / cos(t)
tan(-t) = -tan(t)
c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function). Therefore, y = tan(t) is symmetric about the origin.
