Answers
Answer:
p = 26
Step-by-step explanation:
(p+4)/6 = 5
Multiply each side by 6
(p+4)/6 *6 = 5*6
p+4 = 30
Subtract 4 from each side
p+4-4 = 30-4
p = 26

Domain refers to the permissible values of x
since the given function won't be defined at x=0 and x=9
Also the value of the given function should be greater than 0 or else the square root function won't be defined
therefore the domain of the function is :

so the quadratic formulat is (-b+/-(squrt(b^2-4ac)))/(2a)=x
subsitute
ax^2+bx+c=
9=a
12=b
4=c
(-12+/-(squrt(12^2-4(9)(4))))/(2(9))=x
(-12+/-(squrt(144^2-144)))/18)=x
(-12+/-0)/18)=x
-12/18=x

Answer:
Savannah's annual salary is $ 78260 .
Step-by-step explanation:
As given
Savannah Bryan is career coach.
Her biweekly salary is $3010.
Thus
Here
Total salary = $3010
Number of months = 2
Put all the values in the above
One week salary = $ 1505
As there are 52 weeks are in one year .
Thus
Savannah's annual salary = Number of weeks in a year × One week salary
Put all the values in the above
Savannah's annual salary = 52 × $1505
= $ 78260
Therefore Savannah's annual salary is $ 78260 .

What is the solution to the system of linear equations? Round to the nearest tenth as needed.
Answers
2x + 3y = 16.9
3y = -2x + 16.9
y = (-2/3)x + 16.9/3
5x = y + 7.4
5x - 7.4 = y
So in the graphing calculator,
Y1 = (-2/3)x + 16.9/3
Y2 = 5x - 7.4
Then find the point of intersection and the x value of that would be the solution.
You get the coordinate (2.3, 4.1). So x = 2.3, y = 4.1
Taking into account the definition of a system of linear equations, the solution to the system of linear equations is x=2.3 and y=4.1
System of linear equations
A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.
This case
In this case, the system of equations to be solved is
There are several methods to solve a system of equations, and it is decided to solve it using the graphical method, which consists of representing the equations on a graph, in the same coordinate system. The intersection of the lines representing the equations is the solution of the system.
In this case, the graph is observed in the attached figure, where it can be seen that the intersection of both lines is the point (x,y)= (2.3,4.1).
Finally, the solution to the system of linear equations is x=2.3 and y=4.1
