Step-by-step explanation:
we first square both sides to eliminate the square root brackets..
(√(m(y+n)/y)²= p²
m(y+n)/y = p²
(my +mn)/y =p²
so we multiply both sides by y to eliminate the denominator,
(my+mn)/y*y =p²*y
my+mn = p²y
collecting like terms,we have:
mn= p²y-my
so we seperate the y on the right hand side from the rest to have
mn = y(p²-m)
so divided both sides by the value in the bracket on the right hand side we have..
mn/(p²-m)=y(p²-m)/(p²-m)
so we have,
y= mn/(p²-m)
Answer:
y = [tex]\frac{-mn}{m-p^2}[/tex]
Step-by-step explanation:
Given
[tex]\sqrt{\frac{m(y+n)}{y} }[/tex] = p ( square both sides )
[tex]\frac{m(y+n)}{y}[/tex] = p² ( multiply both sides by y )
m(y + n) = p²y ← distribute parenthesis on left side
my + mn = p²y ( subtract p²y from both sides )
my - p²y + mn = 0 ( subtract mn from both sides )
my - p²y = - mn ← factor out y from each term on the left side
y(m - p²) = - mn ← divide both sides by (m - p²)
y = [tex]\frac{-mn}{m-p^2}[/tex]

Is y=1/2x-1 proportional
Answers
Answer: No
Step-by-step explanation: Since y=2x+1 does not pass through the origin (i.e. there exists the constant term of 1 ), the variables y and x are not directly proportional - though, they do have a linear relationship.
Which of the following polynomial functions is graphed below?
Answers
Answer: B. f(x)=(x+4)(x-2)^2(x+3)
Step-by-step explanation:
in the graph there's two negative x value and one positive x value
so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)
the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))

Which ordered pairs are solutions to the inequality y - 3x < -8?
Select each correct answer.
(1, -5)
(-3, - 2)
(0, -9)
(2, -1)
(5, 4)
Answers
Answer:
The ordered pairs which are solution to given inequality are:
(0,-9)
(5,4)
Step-by-step explanation:
In order to check if the given ordered pairs are solution of the inequality or not we will put the ordered pairs one by one in the inequality.
If the inequality is holds true for the ordered pair, the ordered pair is the solution.
The inequality is:
[tex]y - 3x < -8[/tex]
So,
For (1,-5):
[tex]y - 3x < -8\\-5-3(1) < -8\\-5-3<-8\\-8<-8[/tex]
(1,-5) is not the solution of given inequality.
For (-3,-2):
[tex]-2 - 3(-3) < -8\\-2+9<-8\\7<-8[/tex]
(-3,-2) is not the solution of given inequality.
For (0,-9):
[tex]y - 3x < -8\\-9-3(0) < -8\\-9 <-8[/tex]
(0,-9) is the solution of the given inequality.
For (2,-1):
[tex]y - 3x < -8[/tex]
[tex]-1 - 3(2) < -8\\-1-3<-8\\-4<-8[/tex]
(2,-1) is not the solution of given inequality
For (5,4):
[tex]y - 3x < -8\\4 - 3(5) < -8\\4-15<-8\\-11<-8[/tex]
(5,4) is the solution of given inequality.
Hence,
The ordered pairs which are solution to given inequality are:

0.2x+2.7x−8.1=6.9+1.1x
The answer is not x = 83 tho
and don't do it for the points
Answers
0.2x + 2.7x - 8.1 = 6.9 + 1.1x
Combine like terms on left side:
0.2x + 2.7x = 2.9x
Now you have:
2.9x -8.1 = 6.9 + 1.1x
Subtract 1.1x from both sides:
1.8x - 8.1 = 6.9
Add 8.1 to both sides:
1.8x = 15
Divide both sides by 1.8:
X = 8.3333 ( round as needed) or as a fraction = 8 and 1/3
Answer:
8.3recurring
Explanation:
0.2x+2.7x =2.9x
rewrite the questions
2.9x-8.1=6.9+1.1x
like terms together. Therefore:
2.9x-1.1x = 1.8x
8.1 will go to the other side of the equal sign. Therefore:
8.1+6.9 = 15
Therefore: 1.8x = 15
x =15/1.8 which is equal to 8.3recurring

The given graphs of the system of equations will have an infinite solution, unique solution and no solution, respectively.
What is a system of equations?The types of system of equations in mentioned below.
Inconsistent System
For a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System
1. Dependent Consistent System
For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.
2. Independent Consistent System
For a system of the equation to be an Independent Consistent System, the system must have one unique solution for which the lines of the equation must intersect at a particular.
A.) For the first graph since the lines overlap or lie on each other, therefore, the given system of equation in the first graph will be of Dependent consistent system. Thus, the system will have an infinite number of solutions.
B.) For the second graph since the lines intersect at a particular point, therefore, the given system of equations in the second graph will be an Independent consistent system. Thus, the system will have a unique solution number of solutions. Also, the solution of the equation is the point at which the lines intersect, therefore, the solution of the system of the equation will lie at (-1,2.)
C.) For the third graph since the lines are parallel to each other, therefore, the given system of equations in the third graph will be an Independent consistent system. Thus, the system will have no solutions.
