Answer:
See below
Step-by-step explanation:
If an expression is not dependent on x, it simplified form must not contain x. To show that this is the case for (a) and (b) we need to simplify them and assess:
(a)
Indeed, does not depend on x!
And (b)
Again, does not depend on x.
Answer:
Worst: That was the worst day of my life.
Confident : I am so confident that I will pass my exams with high grades.
Anxious : She was extremely anxious about her exams.
Bandage : Bandage the foot so that the leg is supported.
Crutches: The man with crutches is my best friend.
The lcm is 104
so
48/104+13/104
=61/104
since it is converted to decimal form
61/104=.59
its greater than 1/2 because 1/2 is only .5
Answer:
Step-by-step explanation:
d = 200 miles
B rate = x
A Rate = x + 20
Each has traveled two hours
The total distance each travels after two hours is 200 miles (they pass each other).
d = r * t
2*x + 2*(x + 20) = 200 Remove the brackets
2x + 2x + 40 = 200 Combine like terms
4x + 40 = 200 Subtract 40 from each side
4x = 200 - 40
4x = 160 Divide by 4
x = 160/4
x = 40
There B's rate is 40 miles / hour
A's rate is 40 + 20 = 60 miles / hour
The answer to your question is x is not equal to -3
f(g(x)) = 1/(x-2+5)
= 1/(x+3)
set denominator = 0
x + 3 = 0
x = -3
