Answer:
We conclude that:
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{4}{2n}+\frac{5}{3c}=1[/tex]
Let us solve for 'c'
[tex]\frac{4}{2n}+\frac{5}{3c}=1[/tex]
Least Common Multiplier of 2n, 3c: 6nc
Now multiply both sides by LCM = 6nc
[tex]\frac{4}{2n}\cdot \:6nc+\frac{5}{3c}\cdot \:6nc=1\cdot \:6nc[/tex]
Simplify
[tex]12c+10n=6nc[/tex]
Subtract 10n from both sides
[tex]12c+10n-10n=6nc-10n[/tex]
Simplify
[tex]12c=6nc-10n[/tex]
Subtract 6nc from both sides
[tex]12c-6nc=6nc-10n-6nc[/tex]
Simplify
[tex]12c-6nc=-10n[/tex]
Factor 12c - 6nc = 6c(2-n)
[tex]6c\left(2-n\right)=-10n[/tex]
Divide both sides by 6(2-n); n≠2
[tex]\frac{6c\left(2-n\right)}{6\left(2-n\right)}=\frac{-10n}{6\left(2-n\right)};\quad \:n\ne \:2[/tex]
simplify
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]
Therefore, we conclude that:
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]
This relation is an inverse variation. {(–1, 8), (4, –2), (–2, 4)} Which equation represents this relation?
Answer:
[tex]y = -\frac{8}{x}[/tex]
Step-by-step explanation:
Given
Inverse Variation:
[tex]Points: \{(-1, 8), (4, -2), (-2, 4)\}[/tex]
Required
Determine the equation of the relation
An inverse relation is represented as:
[tex]y = \frac{k}{x}[/tex]
Where k = constant of variation
Make k the subject:
[tex]k = xy[/tex]
When x = -1, y = 8
So, we have:
[tex]k = -1 * 8[/tex]
[tex]k = -8[/tex]
When x = 4, y = -2
[tex]k = 4 * -2[/tex]
[tex]k = -8[/tex]
When x = -2, y = 4
[tex]k= -2 * 4[/tex]
[tex]k = -8[/tex]
From above calculations, we've established that:
[tex]k = -8[/tex]
Substitute -8 for k in [tex]y = \frac{k}{x}[/tex]
[tex]y = \frac{-8}{x}[/tex]
[tex]y = -\frac{8}{x}[/tex]
Hence, the equation is:
[tex]y = -\frac{8}{x}[/tex]

5x - y -= 3
x + 2y = 5
Answer:
1)y=-3+5x
2)y=5/2-1/2x
Step-by-step explanation:
for both equations
1) get your y by it self (subtract -5x and your new equation is now -y=-5x+3)
2)(reminder y can't be negative if it is negative) then you divide by -1 of both sides
3) your equation should now be y=5x-3

what must be the value of a and b for PQRS to be a parallelogram?
Answer:
a = 2
b = 4
Step-by-step explanation:
In parallelogram opposite sides are equal.
4a + b = 2a + 8
4a - 2a + b = 8
2a + b = 8 -----------------(I)
b = 8 - 2a
11b - 10a = 6b
11b - 6b -10a = 0
5b - 10a = 0 ---------(II)
Substitute b = 8 - 2a in equation (II)
5*(8-2a) - 10a = 0
5*8 - 2a * 5 - 10a = 0
40 - 10a - 10a = 0
40 - 20a = 0
-20a = - 40
a = -40/-20
a = 2
Plugin a = 2 in equation (I)
2*2 + b = 8
4 + b = 8
b = 8 -4
b = 4
How many solutions does this equation have?
3x - 2(x + 4) = 5x - 8 + 4x

Answer: the equation of this parallel line would be: Answer: y = 5x - 6
Step-by-step explanation:
Slope of the parallel lines are same
So, m= 5
(3,9)
Equation: y - y1 = m(x -x1)
y - 9 = 5(x - 3)
y - 9 = 5x - 3*5
y -9 = 5x -15 {add 9 to both sides}
y - 9 + 9 = 5x - 15 + 9
y = 5x - 6

Select the correct answer.
What are the the values of x and y that satisfy this equation?
(x + yi) + (4+9i) = 9-4i
Answer: Option A; x = 5, y = -13
Step-by-step explanation:
We have the equation:
(x + yi) + (4+9i) = 9-4i
Solving the left side we have:
x + y*i + 4 + 9*i = 9 - 4*i
(x + 4) + (y + 9)*i = 9 - 4*i
The real part is x + 4, and this must be equal to the real part in the right that is 9, then:
x + 4 = 9
x = 9 - 4 = 5
x = 5
And the imaginary part in the left needs to be equal to the imaginary part in the right, then:
y + 9 = -4
y = -4 - 9 = -13
y = -13
then the solution is x = 5, y = -13
The correct option is A
