Answer:

C. (3, -2)

Step-by-step explanation:

x + y = 1 ➡ x = 1 - y we can use this information in the first equation to find the value of y

3x - 5y = 19 replace x with 1 - y

3 ×(1-y) - 5y = 19 ➡ 3 - 3y - 5y = 19 add like terms

-8y = 16

y = -2 if y is 2 then x is

x + y = 1 ➡ x +(-2) = 1 and x = 3

Solve the equation below using a graphing

UNO [17]

Answer:

x = 0.05

x = 1.57

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

What is the multiplicative rate of change of the function?

BartSMP [9]

Answer:

We know that the multiplicative rate of change of a function is the number by which each next term of an exponential function is increasing or decreasing. We can find multiplicative rate of change by dividing any term of the function by its previous term.
