Solve the equation below using a graphing
UNO [17]

Answer:

<em>x = 0.05</em>

<em>x = 1.57</em>

Step-by-step explanation:

The given equation is:

e^x-\ln 2x = 3.7

Moving all terms to the left side:

e^x-\ln 2x - 3.7=0

Now we define a function:

y=f(x)=e^x-\ln 2x - 3.7

The solutions of the equation are the values of x such that y=0.

Since the function cannot be solved by algebraic methods, we use a graphing tool.

Those points where the graph crosses the x-axis are solutions of the equation.

Please refer to the graph in the figure below.

We can clearly identify there are two solutions at

x = 0.05

x = 1.57

Does the Commutative Property of Addition apply when you add two negative integers?
MAVERICK [17]

The commutative property of addition means we can add two integers in any order. So yes, It would still apply to two negative integers (for example, -2 + -3 and -3 + -2 both equal five)

morpeh [17]

Answer:

400 students

X stands for the total amount fo students and multiply that 0.15 becuase we know ti equals 60 and finding X will solve both problems

that’ll give you 400 students

if you check

400*0.15=60
