Answer:
The domain of a function is the set of all "input" or argument values for which the function is defined. This means the function provides an "output" or value for each member of the domain. Meaning a domain/input relates directly to an output.
Hope this helped :)
To solve this you just move the letters and numbers around until you get a different equation that is the same as the original equation.
You can also rule out the last two answers because they don’t have all the values.
P = pie
s=2prh can be written as s/2ph=r if we divide s by 2ph because we need to isolate r because all the answers have r isolated.
So the answer would be b s/2ph=r
Sorry that’s really badly worded and confusing, but I hope it helps.
A) Variable = x ( miles Tim walked )
B) Tim walked X miles, Molly walked 4+x miles ( 4 more than Tim)
Equation: x + x+4 = 10
C) x +x+4 = 10
2x+4 = 10
2x =6
x = 3
D)
Tim walked 3 miles, Molly walked 7 miles
Answer:
Step-by-step explanation:
4x -39 > -43 8x + 31 < 23
Add 39 to both sides Subtract 31 from both sides
4x -39 + 39 > -43 + 39 8x + 31 - 31 < 23 - 31
Simplify Simplify
4x > -4 8x < -8
Divide both sides by 4 Divide both sides by 8
4x / 4 > -4 / 4 8x / 8 < -8 / 8
Simplify Simplify
x > -1 x < -1
Answer: A
