Answer:
The attached image shows the graph for the given function.
Step-by-step explanation:
We are given the following function in the question:
We have to graph the given function.
Properties of the given function are:
- It is an exponential function of the form
- Here, a = 2, b = -1
- The y-intercept of the given function is (0,0.5)
- There is no x-intercept.
- The domain of the given function is all real numbers.
- The range of given function is
The attached image shows the graph for the given function.
Selling 90 would reach her goal of $135 so she would need to sell 91 to exceed her goal
135/1.5=90 so 91*1.5=136.5
Answer:
<h2>
</h2>
Step-by-step explanation:
Solve the equation for y by moving 'x' to R.H.S and changing its sign
Substitute the given value of y into the equation 5x + y = 28
Solve the equation for x
Collect like terms
Move constant to R.H.S and change its sign
Subtract the numbers
Divide both sides of the equation by 4
Calculate
Reduce the numbers with 2
Now, substitute the given value of x into the equation y = 2 - x
Solve the equation for y
The possible solution of the system is the ordered pair ( x , y )
<h2>
</h2>
-------------------------------------------------------------
Let's check if the given ordered pair is the solution of the system of equation:
plug the value of x and y in both equation
Simplify the equalities
Since , all of the equalities are true, the ordered pair is the solution of the system.
Hope this helps....
