Answer: b=4
Step-by-step explanation: Let's solve your equation step-by-step.
4b+5=1+5b
Step 1: Simplify both sides of the equation.
4b+5=5b+1
Step 2: Subtract 5b from both sides.
4b+5−5b=5b+1−5b
−b+5=1
Step 3: Subtract 5 from both sides.
−b+5−5=1−5
−b=−4
Step 4: Divide both sides by -1.
−b
−1
=
−4
−1
b=4
Answer: sqrt(19)/10
Step-by-step explanation:
sinx=0.9
x=arcsin(0.9)
Insert x for cos(x):
cos(arcsin(0.9)=

Sorry if this is confusing.
Answer:
x = 3.4
Step-by-step explanation:
Given the graphs of 2 functions, then the solutions to both are at their points of intersection, that is
where f(x) = g(x)
There are 3 possible points of intersection to f(x) = g(x)
The one on the list , however, is at x = 3.4
